WARNINGS, CAUTIONS AND NOTES

The following notations are used to place special emphasis on procedures, or to call attention to precautionary measures.

WARNING

An operating procedure, practice and so forth, which if not followed correctly, could result in personal injury, or loss of life.

CAUTION

An operating procedure, practice and so forth, which if not followed correctly, could result in damage to, or destruction of equipment.

NOTE

An operating procedure, condition and so forth, to which special attention should be paid.

GENERAL SAFETY PRECAUTIONS

During transmission, high RF voltages may appear at the RF connectors of the transceiver, antenna tuner (ATU), the antenna cable, and on the antenna itself.

Avoid touching the antenna and the RF connectors of a radio set while it operates.

Make sure the antenna is not located near high-voltage lines.

Operating and maintenance personnel must be familiar with the applicable safety requirements and regulations before attempting to install or operate the radio set.

The following are general safety precautions that are not related to any specific procedures and therefore do not appear elsewhere in this publication. These are recommended precautions that personnel must understand and apply during various phases of operation and maintenance.

KEEP AWAY FROM LIVE CIRCUITS. Operating personnel must at all times observe all safety regulations. Do not replace components or make adjustments inside the equipment with the high voltage supply turned on. Under certain conditions, dangerous potentials may exist even when the power control is in the OFF position, due to charges retained by capacitors. To avoid casualties, always remove power and discharge and ground a circuit before touching it.

DO NOT SERVICE OR ADJUST ALONE. Under no circumstances should any person reach into the equipment enclosure for the purpose of servicing or adjusting the equipment except in the presence of someone who is capable of rendering aid.

RESUSCITATION. Personnel working with or near high voltages should be familiar with modern methods of resuscitation.

USE SAFETY APPROVED EQUIPMENT. When cleaners and primers are being applied, approved explosion-proof lights, blowers, and other equipment shall be used. Insure that firefighting equipment is readily available and in working order.

GIVE CLEANERS SPECIAL CARE. Keep cleaners in special polyethylene bottles or in safety cans and in minimum quantities. Discard soiled cleaning cloths into safety cans.

Product Safety and RF Exposure for Mobile Two-Way Radios Installed in

Vehicles or as Fixed Site Control Stations

Compliance and Control Guidelines and Operating Instructions for Mobile Two-Way Radios

Installed in Vehicles

To control your exposure and ensure compliance with the occupational/controlled environment exposure limits, always adhere to the following procedures:

• To transmit (talk), push the Push-To-Talk (PTT) button; to receive, release the PTT button. Transmit only when people outside the vehicle are at least 7 feet from a properly installed, externally-mounted antenna.

• In as far as possible, install mobile antennas at the center of the roof or the center of the trunk deck.

Compliance and Control Guidelines and Operating Instructions for Mobile Two-Way Radios

Installed as Fixed Site Control Stations

If mobile radio equipment is installed at a fixed location and operated as a control station or as a fixed unit, the antenna installation must comply with the following requirements performance and compliance with the RF energy exposure limits in the standards and guidelines:

• The antenna should be mounted outside the building on the roof or a tower if at all possible.

• As with all fixed site antenna installations, it is the responsibility of the operator to manage the site in accordance with applicable regulatory requirements and may require additional compliance actions such as site survey measurements, signage, and site access restrictions in order to ensure that exposure limits are not exceeded.

Electromagnetic Interference/Compatibility

NOTE

Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately shielded, designed, or otherwise configured for electromagnetic compatibility. It may be necessary to conduct compatibility testing to determine if any electronic equipment used in or around vehicles or near fixed site antenna is sensitive to external RF energy or if any procedures need to be followed to eliminate or mitigate the potential for interaction between the radio transmitter and the equipment or device.

Facilities

To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio in any facility where posted notices instruct you to do so. Hospitals or health care facilities may be using equipment that is sensitive to external RF energy.

Vehicles

To avoid possible interaction between the radio transmitter and any vehicle electronic control modules, for example, ABS, engine, or transmission controls, the radio should be installed only by an experienced installer and that the following precautions be used when installing the radio:

1. Refer to the manufacturer's instructions or other technical bulletins for recommendations on radio installation.

2. Before installing the radio, determine the location of the electronic control modules and their harnesses in the vehicle.

3. Route all radio wiring, including the antenna transmission line, as far away as possible from the electronic control units and associated wiring.

OM-E 2072-09566-00

iii

Driver Safety

Check the laws and regulations on the use of radios in the area where you drive. Always obey them.

When using your radio while driving, please:

• Give full attention to driving and to the road.

• Pull off the road and park before making or answering a call if driving conditions so require.

Operational Warnings

WARNING

For Vehicles with an Air Bag

Do not mount or place a mobile radio in the area over an air bag deployment area. Air bags inflate with great force. If a radio is placed in the air bag deployment area and the air bag inflates, the radio may be propelled with great force and cause serious injury to occupants of the vehicle.

Potentially Explosive Atmospheres

Turn off your radio prior to entering any area with a potentially explosive atmosphere. Sparks in a potentially explosive atmosphere can cause an explosion or fire resulting in bodily injury or even death.

The areas with potentially explosive atmospheres include fueling areas such as below decks on boats, fuel or chemical transfer or storage facilities, and areas where the air contains chemicals or particles such as grain, dust or metal powders. Areas with potentially explosive atmospheres are often, but not always, posted.

WARNING

Blasting Caps and Blasting Areas

To avoid possible interference with blasting operations, turn off warning your radio when you are near electrical blasting caps, in a blasting area, or in areas posted: "Turn off two-way radio". Obey all signs and instructions.

For radios installed in vehicles fueled by liquefied petroleum gas, refer to the (U.S.) National Fire Protection Association standard, NFPA 58, for storage, handling, and/or container information. For a copy of the LP-gas standard, NFPA 58, contact the National Fire Protection Association, One Battery Park, Quincy, MA.

1-2. MICOM-3 CAPABILITIES

1-2.1 Overview

Micom-3 is a state-of-art family of HF/SSB radio sets designed to meet the demanding requirements of HF communications operational environment. Using advanced digital signal processing (DSP) techniques, Micom-3 offers reliable long-range communication for voice, fax, data, E-mail and telegraphy (CW) traffic. Micom-3 supports upper sideband (USB), lower sideband (LSB), amplitude modulation equivalent (AME), and pilot modes of operation. It supports both simplex (same transmit and receive frequency) and duplex (different transmit and receive frequencies) communication.

As an option, Micom-3 can also support the independent sideband (ISB) mode, which enables to simultaneously communicate on both the upper sideband (USB) and the lower sideband (LSB) of the selected channel (RF carrier frequency), thereby essentially providing two independent channels, each capable of carrying a separate voice call. When using the ISB option with an external modem, the maximum data rate is 19.2 kbps.

Extensive use of digital signal processing (DSP) ensures high performance; a built-in voice quality system with proprietary DSP algorithms filter out background noise and elevates sound bytes providing exceptional communication clarity and voice quality. Many advanced features are standard, such as digital noise blanking and voice-activated digital squelch.

Optional features such as an internal (embedded) data modem supporting data rates up to 4800 bps, embedded vocoder, embedded privacy (by means of AES encryption), internal GPS receiver, etc., are also available. Moreover, the addition of new features and upgrading to future technologies are easily made by software updating.

OM-E 2072-09566-00

To ensure the best possible communication reliability, Micom-3 implements the Automatic Link Establishment (ALE) protocol, and is certified by the Joint Interoperability Test Center (JITC) to MIL-STD-188-141B. In addition, the ALE function also provides Automatic Message Display (AMD), that enables operators to exchange preprogrammed messages while establishing a link. The AMD function is also used in several advanced optional features, such as automatic position reporting (either operator-initiated or in response to queries) when a GPS receiver is installed, and automatic adoption of the privacy key used by the transmitting station (provided the necessary key is available at the receiving station).

When the ALE option is not used, Micom-3 can be configured to automatically scan selected channels, organized in up to five groups, thereby enabling the operator to manually select a good quality channel.

Micom-3 radio sets provide a complete solution to traditional HF communication problems while allowing user-friendly, easy operation even for unskilled users. Micom-3 radio sets have been specifically designed to satisfy all the needs of short, medium and long range communication in the crowded HF band. To simplify installation, the transceivers can also provide DC power through the RF cable to a compatible ATU.

1-2.2 Micom-3 Versions

Three flexible Micom-3 transceiver versions are offered, to fit both fixed and mobile installations.

NOTE

The audio accessories are for illustration purposes only, and may vary in accordance with preferences.

1-2.3 Micom-3 Main Characteristics

The main characteristics of the Micom-3 family are described below:

• User-Friendly Operation. The Micom-3 has an intelligent, state-of-the-art, menu-driven man-machine interface (MMI) that is easy to master and intuitive to use, and has optional support for multiple languages.

The MMI is based on a large digital front-panel display with four soft keys, four navigation keys, and a 16-key keypad; the only additional front-panel control is a volume control, integrated with the ON/OFF switch.

The MMI enables the operator to perform any desired action easily and efficiently, for example, select the desired operating mode, define or modify the parameters to be used on each preset channel, etc. Many improvements based on user feedback have been incorporated in the MMI, as a part of an ongoing evaluation program.

Micom-3 can store 200 channels in its memory, each with a complete set of parameters. In addition, Micom-3 radio sets enable control and programming via an RS-232 interface, using a PC running the Micom Radio Control (MRC) application or the Radio Service Software (RSS). The same interface can be used to update in the field the radio software, thereby enabling to add new features and capabilities as they become available.

• Robust, Reliable Link Establishment. Micom-3 radio sets support Automatic Link Establishment (ALE) per MIL-STD-188-141B (the required software is supplied embedded as a standard), ALE operation is very simple, and can be easily used even by unskilled operators.

The ALE AMD function is also used in several advanced optional features, such as automatic position reporting (either operator-initiated or in response to queries) when a GPS receiver is installed, and automatic adoption of the privacy key used by the transmitting station (provided the necessary key is available at the receiving station).

Micom-3 radio sets also support MultiNet, a function that enables seamless integration of nets, by enabling each Micom-3 to receive and transmit ALE calls in several different nets (up to 20).

In addition to the standard ALE capabilities, Micom-3 radio sets supports two enhancements:

Quick Net index-based calling (option). Quick Net is an adaptive multiple networking mode, which expands the capabilities available in the standard (net-based) ALE mode by adding a central index with a capacity of up to 1000 stations (these stations are in addition to the stations defined in the ALE directory for net-based operation). Within this index, each station has a unique index number (000 to 999): this enables the operator to initiate an ALE call simply by providing the destination index number.

Global call mode (option). This option provides operators of large HF networks with the capability to reliably make a call to another station using the global call option. Unlike other ALE calling modes, in the global call mode the purpose is to reliably make contact as rapidly as possible with another station, a useful feature for urgent calls or emergency situations. In each ALE net, you can define different global call characteristics, i.e., for each ALE net, you can select from the ALE directory up to 20 stations to be global call members, irrespective of the stations included in the corresponding ALE net.

For the call to be effective in emergencies, the group of stations that may be contacted by making a global call is a selected subset of the stations included in the ALE directory (the global call members). For operator's convenience, this subset is assigned its own name (the global call name). When you make a global call, Micom-3 automatically selects the global call member station having the channel with the best LQA score, out of the specified subset. In the event all the LQA scores are equal, you can instruct the transceiver which station to call: this station is called the global call priority station (a priority station can be configured for each ALE net). After the call is ended and the link is disconnected, the Micom-3 returns to scan the ALE net channels.

• Internal GPS Receiver. Micom-3 can be ordered with an optional integral Global Positioning System (GPS) receiver, using a compact, light-weight patch antenna with magnetic mount. In addition to presenting the GPS information on the display, the ALE AMD call messaging platform can be used to enable any station to generate a request for GPS location from any other station in the network.

• High Reliability and Cost-Effective Logistics. The modular, 3-board design of the Micom-3 family, with its high MTBF and low MTTR, offers outstanding reliability in field conditions and cost-effective logistic support.

A comprehensive multilevel built-in test (BIT) subsystem helps the user to identify faulty modules in the field, and ensures complete functional testing after module replacement. The BIT also provides valuable information to higher echelon maintenance personnel, without requiring module-level test equipment.

1-2.4 Transmitter Features

The maximum output power of the Micom-3 transmitter is 125 W PEP (Peak Envelope Power). The average transmission duty cycle is up to 1:4, thus enabling even CW (Continuous Wave) signals to be transmitted at the maximum available power.

The transmit power can be selected by the operator for optimum transmission performance (125 W PEP for maximum range; 100 W, 60 W or 25 W to reduce interference to nearby stations, and decrease power dissipation). Accurate sensors are used to keep the output power at the selected value.

The nominal output impedance is 50 Ω, and therefore Micom-3 can be directly connected to broadband antennas (dipoles, traveling wave antennas, delta and semi-delta antennas). For other types of antennas, and for mobile service using whip antennas, an external antenna tuning unit (ATU) is necessary.

The transmitter includes thermal protection. If, for any reason, the transmitter internal temperature exceeds the maximum permitted temperature, the output power is automatically reduced to avoid any fault due to excessive heat. Antenna mismatch protection is also included. If the VSWR (Voltage Standing Wave Ratio) rises to more than 2:1, the transmission will be inhibited to avoid damage and a message will be displayed.

1-2.5 Receiver Features

The receiver has a wide dynamic range and high selectivity, and is protected against overloading and damage by strong RF signals reaching the antenna.

The radio utilizes digital signal processing for implementing most of the receiver functions, e.g., demodulation, narrow band filtering with user-selectable bandwidth to match the service type, automatic gain control, noise blanking, tunable notch filter, squelch, etc. A clarifier with a range of ±200 Hz can be used to shift the actual receive frequency for best voice clarity, and an automatic digital noise blanker is activated whenever repetitive noise (e.g., ignition spikes) is encountered in the received signal.

The digital syllabic (speech identifier) squelch is activated whenever speech is identified, thus opening the audio path. However, if speech is not received, the audio path is muted, thus preventing background noise from disturbing the operator.

1-2.6 Internal GPS Receiver (Option)

The internal GPS receiver is a standard L1-band C/A SPS receiver that can provide navigation and time-of-day data. The minimum number of satellites that must be received is four, but the receiver can simultaneously receive and process a larger number of satellites to improve the positioning accuracy.

The optional GPS receiver is supplied with an omnidirectional GPS antenna with magnetic mount, which can be located at up to 5 meters (15 feet) from Micom-3.

1-2.7 Internal Modem (Option)

The internal modem is a 4800 bps modem that uses the waveforms specified by MIL-STD-188-110B Section 5.3.2 and STANAG 4539 Annex B Section 3. The connection to the data equipment (for example, a PC running the MicomNet Email/Internet Gateway software) is made via an RS-232 asynchronous port, and requires only a transmit line and a receive line, both referenced to a common signal ground.

To cope with the multipath fading characteristics of HF radio channels, the modem uses advanced proprietary DSP algorithms that provide outstanding, robust performance.

Advanced error correction and ARQ techniques are used to provide the highest throughput possible over the HF channel, and therefore the actual user data rate can vary in the range of 75 to 2400 bps, in accordance with the propagation conditions. The receiving end automatically detects the incoming data rate, and the modem at the transmitting end automatically detects the source data rate (Autobaud mode): therefore, no operator intervention is needed for reliable communication. Moreover, the modem transmit path automatically detects data activity and provides the PTT signal to the radio.

The PC running MicomNet provides the interface to the user’s side, and therefore it can support any standard interface for connecting to other equipment (serial RS-232, USB, Ethernet, etc.). Moreover, MicomNet can automatically perform data compression for the user’s payload before transferring it to the modem, thereby increasing the effective data rate (for example, for e-mail the effective rate can reach 9000 to 10000 bps).

1-2.8 Internal Vocoder (Option)

The internal vocoder operates at a fixed channel data rate, 1200 bps. The vocoder algorithm provides good voice quality and high intelligibility even over weak or noisy channels, and strong interfering signals: in many cases, vocoder communication is possible even when analog voice is unintelligible.

When both the modem and vocoder are installed, the communication mode is automatically selected in accordance with operator’s requirements:

• Pressing the PTT of the audio accessory connected to the front panel while Micom-3 is idle starts transmission of voice using the vocoder. In this case, data (modem) transmission is possible only after the PTT is released.

• Detection of data activity by the internal modem starts data transmission using the modem. Pressing the PTT during data transmission is ignored.

1-2.9 Encryption Options

Modem and vocoder transmissions can be protected using AES, a widely used encryption standard.

Encryption can be ordered as an option for the internal modem, the internal vocoder, and both the modem and the vocoder. Up to seven keys can be downloaded and stored in Micom-3, using the Micom Key Loader (MKL) software. The operator can select the active key, and can disable encryption and switch to plain transmission. The operator can also erase the stored keys.

1-2.10 Frequency Sources

Two types of frequency sources are available for Micom-3 radio sets:

• Standard 0.6 ppm frequency source, which ensures a frequency accuracy of better than ±18 Hz (for frequencies lower than 10 MHz, the frequency accuracy is better than ±6 Hz)

• When higher frequency accuracy is required, an 0.1 ppm optional frequency source can be ordered, to achieve a frequency accuracy better than ±3 Hz at 30 MHz.

1-2.11 Power Source

The radio is designed for 13.8 V negative-ground operation, for connection to a standard 12 V battery.

1-3.2 Typical System Configurations

Figure 1-1 shows a typical Micom-3F mobile installation. Mobile installations require using a whip antenna, and the ATU illustrated in this application is the F2265 ATU, which is well suited for used with Micom-3 radio sets.

In the application shown in Figure 1-1, Micom-3F (equipped with an internal modem) is also used for data communication, using a portable PC running the MicomNet E-mail/Gateway to Internet software package. Equipping the Micom-3F with the optional GPS receiver provides the mobile user with the option to implement a mobile office environment.

When the extent of data communication requires prolonged transmission periods, the basic mounting tray illustrated in Figure 1-1 should be replaced by the optional Continuous Duty Tray, FLN2294, which includes cooling fans, powered by Micom-3 through a short cable connected to its rear accessories connector. The tray also includes four 25-pin accessory connectors, which provides access to all the signal and control lines in the rear 44-pin accessories connector of Micom-3, and front jacks for connecting a headphone set and a Morse key.

The use of a heavy-duty ATU, for example, FLN2818, is also recommended.

The system configuration shown in Figure 1-1 can also be used in a fixed station application: in this case, an AC-powered DC power supply/battery charger, for example, FPN5590C, can be used to provide power to the radio set and charge the 12V battery, with the battery serving as backup.

2-3. FAMILIARIZATION WITH MICOM-3 OPERATING PROCEDURES

This section provides general procedures that will help you start using your radio and get the most of its advanced features. Most of the activities that can be performed by you (selection of operating mode, programming, testing, etc.) are done using the keypad together with the navigation and function keys, and the front panel display.

To simplify operation, Micom-3 function keys operate as soft keys and therefore they permit you control the radio simply and efficiently, using a menu-driven mode that guides you and helps you make the required selections. “Menu-driven” simply means that whenever you must select a parameter, an operating mode, etc., you select it from a list of allowed values displayed on the front panel display, thereby reducing the chance of error:

• To make a selection, you use navigation keys to reach the desired parameter value or action, and

then confirm the selection by pressing the ENTER key.

• To go back to previous options, or cancel the current selection or action, press the ESC P.ESC

key.

Make sure to press the next key in a sequence within a few seconds of the previous key pressing. If the interval between consecutive key pressings exceeds the time-out interval, the whole sequence is aborted, and the Micom-3 returns to its previous state.

LSB Using lower sideband for transmission and reception

ISB-U Independent sideband (ISB) mode (option) is enabled, and the main sideband is USB

ISB-L Independent sideband (ISB) mode (option) is enabled, and the main sideband is LSB

SQ Squelch is active: the speaker is turned on only when the radio identifies speech, to prevent reception noise from being heard. For Micom-3R, the squelch function also effects the handset

MON When using ALE, indicates that the speaker is normally off, and is automatically turned on when the link is established. For Micom-3R, the monitor function also effect the handset

AGC Non-standard AGC mode (AGC off, or fast AGC) has been selected

BW Non-standard bandwidth has been selected that is, any bandwidth except 2.7 kHz (the bandwidth appears next to the BW indicator, for example, 3.3 (3.3 kHz) in the screen shown above)

NB Noise blanker is active

CLAR Clarifier is active (you selected a frequency deviating from the nominal channel frequency)

NF Notch filter is active

2-3.1.3 RF Level Indications

Indication Meaning

Strong received signal

Weak received signal

Received RF signal strength indication, displayed when the radio is in the receive mode. The height provides a relative indication, which may fluctuate as a result of fading, etc.

– Full transmit power – Relative transmit power

– Low transmit power

– Reflected power

Transmit bar, appears when the radio is switched to the transmit mode (for example, when the PTT is pressed). Its length indicates the maximum radio transmit power in the selected mode (MAX, HIGH, MED or LO). The triangle height indicates the instantaneous relative transmit output power, and therefore it fluctuates as a result of modulation.

The relative reflected power is indicated by the base line: its length indicates the fraction of power reflected because of antenna VSWR (the length should be small relative to the total height of the transmit bar, which is proportional to the forward power)

OM-E 2072-09566-00

2-12

Use the following description with Figure 2-5, which shows the details of the main menu.

Menu item ... and its purpose

CHAN Channel mode: the radio uses a set of preset parameters. Up to 200 sets of parameters can be defined and stored in the Micom-3, where each set is assigned a channel number (1 to 200). You can use Figure 2-6 to find details on the selections available on the CHAN menu.

FREQ Frequency mode: you can select manually the frequency (free tune mode) and the other parameters to be used. You can use Figure 2-7 to find details on the selections available on the FREQ menu.

ALE ALE mode: when you want to call other radio, the radio automatically sets up a link on the best free frequency that can be found. You can also call specific radio sets, a group of radio, or broadcast to all the radio sets. The sets of parameters needed for this operation mode are stored under net numbers (1 to 20), the radio sets are identified by addresses stored by the radio in a directory supporting up to 100 addresses.

SCAN SCAN mode: when neither the ALE, nor the CCIR mode, is used, you can define a set of channels to be scanned before starting a call. The scan parameters are always loaded by the MRC together with the other operational parameters, and cannot be changed using the Micom-3 panel.

BIT BIT mode: lets you check that the Micom-3 is OK.

LOCK Lock the radio to prevent unauthorized use. To lock and unlock, you enter a password.

PROG Programming mode: lets you program (select and store) the required parameters. Refer to Chapter 4 for details on the selections available on the PROG menu.

PSW Used to change the password.

DIM Used to adjust LCD lighting.

2-3.8 Notational Conventions

In this manual, the following conventions are used to simplify the description of the steps you need to carry out actions using the keys and the LCD:

When a procedure begins with a sequence of steps, that sequence is represented in an abbreviated format, with the > symbol indicating the next key to be pressed.

For instance, the following represents a sequence of steps that involves five key pressings: MENU > MORE > PROG > RAD > CHAN.

2-4. GETTING STARTED

This section provides basic operating instructions: it covers issues such as turning the radio on and off, selecting a channel or a frequency, receiving and transmitting, etc.

You can use these instructions to start using your Micom-3 radio. To become familiar with all the radio capabilities and features, refer to the following sections:

• The information needed to use the Micom-3 CHAN mode appears in para. 2-5 .

• The information needed to use the Micom-3 FREQ mode appears in para. 2-6.

• The information needed to use the Micom-3 SCAN mode appears in para. 2-7.

• The information needed to use Micom-3 in the ALE mode appears in para. 2-8.

• The information needed for data communication appears in para. 2-9.

• The information needed to use the Micom-3 vocoder appears in para. 2-10.

• The information needed to use the Micom-3 GPS receiver appears in para. 2-11.

In most cases, the radio reaches you after being configured for use in your radio net. However, if you need to make changes, refer to Chapter 4.

2-4.1 General Information

The radio can receive and transmit in response to four different types of PTT signals:

• MIC PTT – PTT from the microphone or handset connected to the front panel connector; transmits your voice.

• Voice PTT – PTT from an accessory connected to the radio set through its rear panel accessories connector; it causes the radio to transmit the voice signal provided by the accessory device.

• Data PTT – PTT from an accessory connected to the radio set through its rear panel accessories connector; it causes the radio to switch to the data mode and transmit the modem signal.

• CW PTT – PTT from a Morse key connected to the radio set through its rear panel accessories connector; it causes the radio to switch to the CW (Morse) transmission mode.

NOTE

For CW communication, the squelch should be set to OFF.

When using the internal modem, data transmission is controlled by an internal PTT line.

The radio operating mode is automatically adapted for best performance with the signal expected for the active PTT type. This includes two main issues: optimal signal processing, and optimal selection of filter bandwidth.

The filter bandwidth depends on the type of signal to be transmitted and received. A default filter bandwidth can be configured for each channel. The following table, and the associated notes, will help you to select the correct bandwidth, in accordance with the required communication service. If no particular filter is set for the current channel, the radio retains the previously used filter.

Service type Set bandwidth to:

Data 2.1 K

Clear (analog) voice 2.7 K

Data 3.0 K

High speed data or digital voice (vocoder) 3.3 K

Morse CW

Low speed data LSM

OM-E 2072-09566-00

2-14

NOTES

• When the filter bandwidth is set to CW, the following CW bandwidths can be configured using MENU > MORE > PROG > RAD > PRMT: 0.25 K, 0.5 K or 0.8 K.

• When the internal modem is installed or either the digital (DIG) or privacy (PVT) mode is enabled, the radio automatically selects the 3.3 kHz bandwidth.

• When the channel bandwidth is configured to 2.7 kHz, the radio uses the 2.7 kHz bandwidth when operating in the clear (CLR) mode, and the 3.3 kHz bandwidth when operating in the digital (DIG) or privacy (PVT) mode. If the channel bandwidth is configured to 3.3 kHz, the radio uses the 3.3 kHz bandwidth irrespective of the selected mode.

2-4.2 Turning the Radio On and Off

To turn the radio on:

1. Turn the ON/OFF/VOLUME knob clockwise to midrange. You may hear a click as the radio is turned on.

2. The display turns on and shows SELF TEST for a few seconds.

NOTE

If the display is too dim, adjust its brightness using MENU > MORE > DIM > LEVEL. However, this change is temporary: the dimming level returns to the default setting (1) after 10 seconds. Each key pressing will extend the time-out interval by 10 seconds.

If automatic dimming is enabled (DIM is YES), the display may turn off after a few seconds of inactivity. To cancel this feature, use MENU > MORE > PROG > RAD > PRMT > MORE > MORE > DIM to select NO for DIM.

SELF TEST

3. If the self-test procedure is successfully completed, the radio automatically resumes operation in the last used mode (CHAN, FREQ, ALE, or SCAN).

If a problem is detected during self-test, the display shows ERR and a code number, followed by a concise description of the error (if the description does not fit in one row, its parts alternate in the display). If the detected problem does not prevent using the radio, press EXIT to cancel the display and continue.
