3.1 WARNINGS AND ALERTS

Radio Frequency energies

There may be situations, particularly the workplace environments near high-powered RF sources,where recommended limits for safe exposure of human beings to RF energy could be exceeded. Insuch cases, restrictive measures or actions may be necessary to ensure the safe use of RF energy.

High voltage

The equipment has been designed and constructed as to prevent as far as reasonably practicabledanger. Any activity, such as installation, operation and maintenance, on or near the equipment mustbe as far as reasonably free from danger.

Where there is a risk of damage to electrical systems due to adverse weather, extreme temperatures,wet, corrosive or dirty conditions, flammable or explosive atmosphere, then the system must besuitably installed to avoid such a danger.

Protective Earthing

Equipment provided for the purpose of protecting individuals from electrical risk must be properly usedand maintained.

Handling Precautions

Precautions should be taken in equipment handling activities including lifting, lowering, pushing, pulling,carrying, moving or holding, or the activities to restrain an object, animal or a person from theequipment, or the activities when extra efforts are needed such as pulling a lever, or operating powertools.

10 / 29


ESD

Take necessary precautions when handling ESD-sensitive devices. Assume that all solid-state electronicdevices are ESD-sensitive. Do use a grounded wriststrap or the like while working with ESD-sensitivedevices. Transport, store, and handle ESD-sensitive devices in static-safe environments.

3.2. SITE CONSIDERATIONS

The repeater is designed to be used for indoor coverage, so temporary protection should be takenwhen the equipment enclosure is opened for installation or maintenance. The equipment must not beopened for installation or maintenance in bad environment (e.g. gale, storm, extreme temperatures andhigh humidity).

3.3 INSTALLATION LOCATION

Mounting surface shall be suitable to support the equipment weight: for this equipment, the weight is about9kg and the necessary installation space is about 420*300*100mm. The downlink maximum input signalpower at Repeaters donor port should be not more than - 25dBm.

3.4 ISOLATION

Commonly, to prevent repeater from oscillation, the isolation between donor antenna and serviceantenna should Max gain + 15dB. For the GSM900 pico repeater, onsite isolation between donorantenna and service antenna should be not less than 75dB.

Isolation is not usually a problem when a directional antenna is used for the Donor and/or theCoverage antenna. Of course, pointing either antenna at the other would cause a problem and shouldnot be done. In addition, since directional antennas have a narrow pattern, compared to anomni-directional antenna, it is unlikely they will overlap when the directional Donor antenna is high upon the building and the Coverage antenna is low inside the building (in most cases).

Lastly, isolation can be eliminated by the same things that cause reception problems in the first place.Those things being concrete, steel, brick, aluminum, etc. Placing these materials between theantennas prevents their signal patterns from overlapping. For example, your building has a metal roofand you install the Donor antenna above the roof and the Coverage antenna below the roof. Theantennas are effectively isolated.

11 / 29


3.5 ENVIRONMENTAL

Humidity can affect the reliability of the equipment. It is recommended to install the equipment in thelocation having stable temperature and un-restricted air-flow. This equipment is designed to operatewithin the air temperature range of 0C to +50C when the relative humidity 95%. The barrier deviceshould be installed to protect the equipment from sunlight exposure.

3.6 POWERING

The power supply adapter provides power to repeater. It operates at 110V-250V/45Hz-55Hz.

3.6.1 Grounding requirement

Verify the equipment has been well grounded, this includes antennas (especially the donor antennas)and all cables connected. Ensure lightning arrester protection for the antennas is properly grounded.

3.6.2 Manual handling

During transportation and installation, take necessary handling precautions to avoid potential physicalinjury to the installation related personnel or damages to the equipment.

3.7 INSTALLATION PROCEDURES

3.7.1 Goods inspection

Verify the number of packages received according to the packing list. Check all packages for external damage; report any external damage to the shipping carrier. If

there is damage, a shipping agent should be present before unpacking and inspecting thecontents because damage caused during transit is the responsibility of the agent.

Open and check each package against the packing list. If any items are missing, please contactGrentech.

Do not remove items from antistatic packing until installation. If damage is discovered at the timeof installation, please contact the shipping agent.

lightning arrestor must be used to between coaxial cable and the repeater output port.3. Connect the power line to repeater, and can control repeater power supply by 10A power brake.

Step 7

Power up the system and check for signal inside the building. If needed, tune system by moving and orpointing the Donor and Coverage antennas until they get the most signal possible.

Step 8

Secure all antennas and cables, securely mount the repeater and clean up the installation.

Step 9

Ground connection: To ensure safe operation of the product, a ground (earth) connection is required.For single phase AC power source, the product must be grounded by connecting the earth wireof thepower cord to the ground terminal of the AC supply. For operating this product with DC power system(such as rectifiers), the product should not be connected to power systems that switch open the returnlead because the return lead could function as the ground (earth) connection for the equipment. Ingeneral, do not connect the supply before establishing an adequate ground (earth) connection.

Power failure alarm: When the repeaters have abnormal power supply due to a poweroutage or other reasons, the monitoring module will send the power failure alarmto the

NMS by using the backup battery. For GreTech power modules, the normal input voltage

range is 180~260V, and the normal output voltage range is 7~11V. Alarms will occur

beyond this range.

Power module status alarm: This is reserved for the solar energy battery, and currentlyour devices do not support this interface.

Self-excitation alarm: The device experiences self-excitation and fails to work normally.This will affect the device and the wireless network and may even interfere with the BTS in

the worst case. When self-excitation occurs, the GrenTech devices will automatically shut

down the power amplifier and report an alarm. When the NMS receives the alarm and the

self-excitation temporarily clears since the power amplifier is turned off. Self-excitation that

occurs after it is put into service may be due to the following reasons: 1) The location of

the antenna is deviated and this reduces the isolation, which needs on-site check; 2) The

host BTS or the surrounding radio environment changes, in which case the device

parameters need to be adjusted accordingly; 3) The gain and attenuation of the device are

not set properly, in which case you can query the history records in the NMS and modify

accordingly.

Door control alarm: The chassis of the device is opened; the door of the chassis is notclosed properly after site upgrade or debug, or the door is closed properly but the door

control switch is damaged. All these could cause such alarm.

Failure of the uplink low-noise amplifier: The device fails to work normally, the uplinksignals are affected, and the calls may be not available in the coverage area. On-site

handling is required.

Failure of the downlink low-noise amplifier: The device fails to work normally, thedownlink signals are affected, and the calls may be not available in the coverage area.

On-site handling is required.

Overpower of the uplink power amplifier: The output power of the uplink poweramplifier is above the set threshold and this may cause interference to the BTS. You can

increase the attenuation of the uplink power amplifier to adjust the uplink output power by

remote control on the NMS.

Overpower of the downlink power amplifier: The output power of the downlink poweramplifier is above the set threshold and this may affect the coverage area of the repeater.

You can increase the attenuation of the downlink power amplifier to adjust the downlink

output power by remote control on the NMS.

Over-temperature of the uplink power amplifier: The temperature of the uplink poweramplifier is too high (the threshold for GrenTech device is 70 C), and this may cause the

power amplifier module to work abnormally.

Over-temperature of the downlink power amplifier: The temperature of the downlinkpower amplifier is too high (the threshold for GrenTech device is 70 C), and this may

cause the power amplifier module to work abnormally.

VSWR alarm of the uplink power amplifier: The RF signals of the uplink power amplifierof the repeater are not effectively outputted via the antenna, and calls cannot be

connected normally in the coverage area. The possible reason is that the antenna feeder

connector is in loose contact or flooded.

SWR alarm of the downlink power amplifier: The RF signals of the downlink poweramplifier of the repeater are not effectively outputted via the antenna, and the signals are

weak in the coverage area.

Rx/Tx signal alarm: This is mainly for the front/back-end communication of the divideddevices, for example, abnormal communication of the monitoring signals between the

input end of the fiber repeater and the coverage end, abnormal communication of the

monitoring signals between the indoor coverage unit and the trunk amplifier. Such alarms

cause the failure of the back-end devices to be monitored on the NMS. Possible causes: 1)

The front-back-end monitoring data cable fails or the connector gets loose or the optical

path attenuation is so large that causes high BER; 2) The front and back-end programs do

not have the same version or the DIP switches are not set correctly on one end.
