D LocationSelect a location which can support the weight of the trans-ceiver and does not interfere with driving. We recommend the

locations shown in the diagram below.

NEVER place the transceiver or remote controller where nor-

mal operation of the vehicle may be hindered or where it

could cause bodily injury.NEVER place the transceiver or remote controller where air

bag deployment may be obstructed.

DO NOT place the transceiver or remote controller where hot

or cold air blows directly onto it.

AVOID placing the transceiver or remote controller in direct

sunlight.

D Separation cable connectionA separation cable (3.5 m; 11.5 ft) is supplied with the IC-2720H.

Connect the controller and the main unit using with the sepa-

ration cable as follows.

IMPORTANT! For the USA version

A ferrite core is supplied within the separation cable. Connect

the cable connector with the ferrite core into the main unit

[CONTROLLER] socket as below.

DMicrophone connectionTwo microphone connectors are available for the IC-2720Hone is on the controller side panel, and another is on the main

D Battery connectionRWARNING NEVER remove the fuse holders from theDC power cable.

NEVER connect the transceiver directly to a 24 V battery. DO NOT use the cigarette lighter socket for power con-

nections. (See p. 6 for details)

Attach a rubber grommet when passing the DC power cable

through a metal plate to prevent a short circuit.

CONNECTING TO A DC POWER SOURCE

D DC power supply connectionUse a 13.8 V DC power supply with at least 15 A capacity.

Make sure the ground terminal of the DC power supply is

grounded.

I Your first contactNow that you have your IC-2720H installed in your car or

shack, you are probably excited to get on the air. We would

like to take you through a few basic operation steps to make

your first On The Air an enjoyable experience.

1. Turning ON the transceiver

Before powering up your IC-2720H, you may want to make

sure the audio volume and squelch level controls are set in

910 oclock positions.

Although you have purchased a brand new transceiver, some

settings may be changed from the factory defaults because

of the QC process. Resetting the CPU is necessary to start

from factory default.

While pushing both bands [M/CALLMW], push [PWR] for1 sec. to reset the CPU.

2. Selecting the main band

The IC-2720H displays 2 frequencies on left and right bands

simultaneously. However, transmission, some switches and

microphone keys operation are accepted for the main band

only.

Push the desired bands (left or right) [MAINBAND] to se-lect the main band.

Q appears for the main band.

Using the HM-133You can select the main band from the HM-133.

3. Selecting the operating frequency band

The IC-2720H has 2 m and 70 cm bands for each left and

right band. The operating band can be exchanged between

them, and the same bands, V/V and U/U settings are also

possible.

Push the desired bands (left or right) [MAINBAND] for1 sec. then rotate the appropriate bands [DIAL]. Push the [MAINBAND] momentarily to return to frequency indi-

cation.

4. Tune the frequency

The tuning dial will allow you to dial in the frequency you want

to operate. Pages 13 and 14 will instruct you on how to set

the tuning speed.

Using the HM-133You can directly enter the frequency with the HM-133 keypad

for the main band.

I Repeater operation1. Setting duplex

Push desired bands [MAINBAND] to select the main band.Push [DUPMONI] once or twice to select minus duplex orplus duplex. The USA version has an auto repeater function, therefore, setting

duplex is not required.

2. Repeater tone

Push [TONEDTMF] several times until T appears, if the re-peater requires a subaudible tone to be accessed.

Using the HM-133Plus or minus duplex selection and the repeater tone setting

can be made easily via HM-133.

Push [DUP 7(TONE)] for minus duplex; [DUP+ 8(TSQLS)]

for plus duplex selection, push [FUNC] then [DUP 7(TONE)]

to turn the repeater tone ON.MAIN

I Programming memory channelsThe IC-2720H has a total of 212 memory channels (including10 scan edges and 2 call channels) for storing often used op-

erating frequency, repeater settings, etc.

Any memory channel can be recalled from either left or right

band.

1. Setting a frequencyIn VFO mode, set the desired operating frequency with re-

peater, tone and tuning steps, etc.

Push the desired bands [V/MHzSCAN] to select VFO. Rotate the same bands [DIAL] to set the desired frequency.

Set other data, such as repeater tone, duplex information, tuning

step), if desired.

2. Selecting a memory channel

Push the same bands [M/CALLMW] for 1 sec., then rotatethe [DIAL] to select the desired memory channel. ! indicator and memory channel number blink.

3. Writing a memory channel

Push and hold the [M/CALLMW] for 1 sec. to program. 3 beeps sound

Return to VFO mode automatically after the program.

Memory channel number automatically increases when continuing

to push the [M/CALLMW] after programming.

ating frequency via the keypad. Set other data, such as repeater tone, duplex information,tuning step, if necessary.

For radio communications, the antenna is of critical impor-

tivity. The transceiver accepts a 50 antenna and less

than 1:1.5 of Voltage Standing Wave Ratio (VSWR). High

SWR values not only may damage the transceiver but alsolead to TVI or BCI problems.

About extra frequency bands

USA and General versions only

In addition to the 2 m and 70 cm ham bands, the IC-2720H

USA and General versions have extra frequency bands for

each left and right bands as follow.

See the specifications for the available frequency bands fordetails.

*The frequency band initials are default indication only. Once the op-

erating frequency is set in the band, the initial indication will be

changed. : Available, : Not available

ISquelch attenuatorThe transceiver has an RF attenuator related to the squelch

level setting. Approx. 10 dB attenuation is obtained at maxi-

mum setting.

The squelch attenuator allows you to set a minimum signal

level needed to open the squelch. The attenuator function can

be deactivated in initial set mode.

Rotate [SQL] clockwise past the 12 oclock position to ac-tivate the squelch attenuator. Attenuation level can be adjusted up to 10 dB (approx.) between

12 oclock and fully clockwise position.

When setting the squelch from the microphone, a level greater

than 19 activates the squelch attenuator.

too loudly. This may distort the signal.

tRelease [PTT] to return to receive.

ISelecting output powerThe transceiver has 3 output power levels to suit your oper-

ating requirements. Low output powers during short-distance

communications may reduce the possibility of interference to

other stations and will reduce current consumption.

the power amplifier circuit from high SWR (Standing Wave

Ratio) and temperature. When a high SWR antenna or no

antenna is connected, or when the transceiver temperature

becomes extremely high, the transceiver reduces transmitoutput power to 15 W (approx.) automatically.

IGeneral

Repeaters allow you to extend the operational range of your

radio because a repeater has much higher output power than

the typical transceiver.

Normally, a repeater has indipendent frequencies for each re-

ceiver and transmitter.A subaudible tone may also be required to access a repeater

Reference amateur radio hand books and local ham maga-

zines for details of local repeaters such as repeater input/out-

put frequencies and locations.

Repeater operation flow chart

The IC-2720H USA version has the auto repeater function. Thus the

steps 3 and 4 may not be necessary, depending on the setting. Repeater settings can be stored into a memory channel.

Step 3:

Set the duplex (shifting) direction ( duplex or +duplex).- Set the offset frequency (shifting value), if required.

Step 4:Set the subaudible tone (repeater tone) encoder function ON.- Set the subaudible tone frequency, if required.

Step 1:

Set the desired band to operate the repeater.

Step 2:

Set the desired receive frequency (repeater output frequency).

Repeater example;

Receives the 444.540 MHz signaland the detected audio signals aretransmitted on 449.540 MHz simul-taneously.

I General descriptionThe transceiver has 212 memory channels including 10 scan

edge memory channels (5 pairs), and 2 call channels. Each of

these channels can be individually programmed with operating

frequency (pgs. 1113), duplex direction (p. 23) and offset

(p. 27), subaudible tone encoder or tone squelch and its tone

frequency (pgs. 23, 25, 52, 53) and skip information* (p. 44).

In addition, a total of 10 memory banks, A to J, are availablefor usage by group, etc.

*except for scan edge memory channels.
