Page 10
The repeater can be installed in a rack, bracket and cabinet or on a desk.
3. Installation Tool
Tools required for installing the repeater include a cross head screwdriver, a torx
screwdriver and a spanner.
Note: please refer to Safety Information Booklet for more information.
Before Installation
1. Voltage Check
Please check whether the voltage of DC power or external battery meets the repeater
specifications.
2. Product Check
Please check whether the repeater works properly by observing the 8 LEDs located on
the front panel.
3. Parameter Configuration
When the repeater proves to work normally, configure appropriate parameters according
to your actual requirements.And then you can proceed with on-site installation.
Installation Steps
Install the repeater as follows:
1. Install the repeater at a proper location;
2. Attach all necessary accessories;
3. Ground the repeater through the Ground Screw located on the rear panel.
Note: if the repeater needs to work with a duplexer, you should implement the
following operations before installation.

9
Page 11
2. Install the duplexer onto the bracket. Be sure to observe the specifications of two
antenna interfaces on the duplexer, to determine which one should be connected to
the transmitter. The interface connecting the transmitter should be close to PA
module to reduce RF loss, as shown below:
3. Loosen the screw at the back of the top cover, and then pull the top cover to remove
it.
4. Loosen the 6 screws locking the PA heat sink, disconnect all power, data and RF
cables, and finally remove the heat sink.

Basic Operations
Turning the Repeater On/Off
ON:turn on the repeater by connecting a DC power supply to it. During power-up process,
the Power indicator glows green and the LCD shows animation.
OFF: Disconnect the DC power supply.
Adjusting Volume
In analog mode: rotate the Volume Control knob clockwise to increase the volume or
counter-clockwise to decrease the volume.
In digital mode: the speaker is muted, so this knob does not work.

repeater coverage, enabling you to communicate with farther terminals. The TX power is
represented by the icon and respectively on the LCD.
Backlight
Activating the backlight can illuminate the LCD and all the front panel keys, so as to
facilitate your operation.
You dealer can set the backlight to operate in any of the following modes:
Timed: either key press or knob operation can activate the backlight. If no foregoing
event occurs within the specified time period, the backlight will go out automatically.
Enable: the backlight remains activated all the time.
Note: When an alarm event occurs, the backlight will remain activated until the alarm
disappears.

Alarm Information
The repeater can automatically detect its operation status in a real time way. When an
abnormality occurs, the LCD will give you a prompt message, and the Alarm Indicator will
glow red.
Over Temperature Alarm
When the temperature of PA module exceeds the normal range, the Alarm Indicator will
16
Page 18
glow red and the LCD will display the prompt message below:
Then the repeater will stop transmitting, and you need to:
1. Check whether the temperature of heat sink surface is over 80℃. If yes, proceed with
Step 2 and 3 to find out the cause.
Caution: DO NOT touch the heat sink surface to avoid burn. You can use a digital
thermometer with thermocouple to measure the temperature value.
2. Check whether ambient temperature and ventilation conditions satisfy the foregoing
installation requirements.If not, please make improvements as soon as possible.
3. Check if connection between the transmitter and RF cable or antenna feeder is loose
or damaged. Poor connection between them could cause high TX power, which would
make the temperature of heat sink rise quickly. If yes, secure or replace the cable or
antenna feeder.
4. If the above measures fail to solve the problem, contact your local dealer for technical
support.
When temperature falls into normal range, the prompt message will disappear, and the
Alarm Indicator will go out.
Fan Failure Alarm
When the fan fails to work, the Alarm Indicator will glow red and the LCD will display the
prompt message below:
17
Page 19
Then the repeater will automatically work at low TX power, to protect the transmitter from
overheating. You need to:
1. Check whether the fan is blocked by an object. If yes, remove it.
2. If you cannot solve the problem, contact your local dealer for technical support.
When the fan recovers normal operation, the prompt message will disappear, and the
Alarm Indicator will go out.
VSWR Alarm
High VSWR (voltage standing wave ratio) of TX antenna connector could result in
damage to the PA, and even failure of the transmitter. When the VSWR exceeds the
normal range, the Alarm Indicator will glow red and the LCD will display the prompt
message below:
Then the repeater will automatically works at low TX power.You need to:
1. Check if the operating frequency of repeater is in line with that of antenna. Both
frequency mismatch and improper antenna could result in poor transmitting
performance and even damage to the transmitter. If yes, please contact your local
dealer to replace the antennaor reprogram your product.
18
Page 20
2. Check if the connection between the transmitter and RF cable or antenna feeder is
loose or damaged. If yes, secure or replace the cable or antenna feeder.
3. If you cannot solve the problem, contact your local dealer for technical support.
When the VSWR falls within the normal range, the prompt message will disappear, and
the Alarm Indicator will go out.
Low Forward Power Alarm
When the forward power is below the preset value, the Alarm Indicator will glow red and
the LCD will display the prompt message below:
Then the repeater may continue transmission or terminate it, subject to the detection
result. You need to:
1. Check if the connection between the transmitter and RF cable or antenna feeder is
loose or damaged. If yes, secure or replace the cable or antenna feeder.
2. If you cannot solve the problem, contact your local dealer for technical support.
When the forward power is recovered to its normal value, the prompt message will
disappear, and the Alarm Indicator will go out.
Over/Low Voltage Alarm
When power voltage is detected to be over or below the normal range (11V-15.6V) of
repeater, the Alarm Indicator will glow red and the LCD will display the prompt message
below:
19
Page 21
Low Voltage Alarm Over Voltage Alarm
Then the repeater will automatically stop working. You need to:
1. Check whether the power voltage is too low or too high. If yes, replace the DC power
supply or external battery.
2. Check whetherthe power cord is loose or damaged. If yes, secure or replace the cord.
3. If you cannot solve the problem, contact your local dealer for technical support.
When the voltage falls within the normal range, the prompt message will disappear, and
the Alarm Indicator will go out.
Caution: If low voltage is detected when the repeater is powered by an external
battery, please charge it in time. Disconnect the battery from the repeater
before charging.
