Duplexer

• Duplexer is a device that allows bi-directional communication. Its role is to isolate the TX signal from the RX signal to ensure that the transmitter and receiver can work normally.

Feed Line

• Feed Line is the cable or transmission line that connects the antenna with the radio transmitter or receiver.

Voltage Standing Wave Ratio (VSWR)

• VSWR is a value that measures how well a load is impedance-matched to a source.

Installation Guide

• Proper installation can ensure optimum performance and reliability of the repeater. Therefore, be sure to read the following instructions before installation.

Installation Requirements

• Installation Environment
• The repeater must be installed in a dry and well-vented l a ted place with an ambient temperature of -30℃~+60℃ and relative humidity of less than 95%.
• Installation Location
• The repeater can be installed in a rack, bracket, cabinet, or on desk.

Installation Tools

• 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

• Voltage Check
• Please check whether the voltage of the DC power or battery meets the repeater specifications.
• Product Check
• Please check whether the repeater works properly by observing the 8 LEDs located in the front panel.
• 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.

Installing the Duplexer
If the repeater needs to work with a duplexer, you should implement the following operations before installation.

1. Loosen the three screws on the bracket with a cross-head screwdriver. See the figure below.

2. Install the duplexer onto the bracket. Be sure to observe the specifications of two antenna connectors on the duplexer, to determine which one should be connected to the transmitter. The connector connecting the transmitter should be close to the 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, remove all power, data, and RF cables from the PA, and finally remove the PA heat sink. See the figure below.

5. Connect the RF cable. See the figure below.

6. Install the duplexer to the repeater.
   After the duplexer is mounted properly, fasten it with the 2 screws inside the housing and on the side respectively.

Alarm Information

The repeater can automatically detect its operation status in real-time. If the appropriate alarm indication option is checked in the CPS by your dealer, the LCD will give you a prompt message, and the Alarm Indicator will glow red in the case of a corresponding abnormality.
Over Temperature Alarm
When the temperature of the PA module exceeds the normal range, the Alarm Indicator will 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 the 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 sur face 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 feed line is loose or damaged. Poor connection between them could cause high TX power, which would make the temperature of the heat sink rise quickly. If yes, secure or replace the cable or antenna feed line.

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:

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 a foreign 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 the 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 the repeater is in line with that of the 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 antenna or reprogram your product.
2. Check if the connection between the transmitter and RF cable or antenna feed line is loose or damaged. If yes, secure or replace the cable or antenna feed line.
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 feed line is loose or damaged. If yes, secure or replace the cable or antenna feed line.
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 range (11V-15.6V) of the repeater, the Alarm Indicator will glow red and the LCD will display the prompt message below:

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 whether the 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.
TX/RX Unlock Alarm
When the TX PLL or RX PLL is unlocked, the Alarm Indicator will glow red and the LCD will display the prompt message below:

Then the repeater will automatically stop partial operations. You need to:

1. Disconnect the power supply, open the chassis and check whether the cabling is right or damaged. If yes, please secure or replace the cable.
2. If you cannot solve the problem, contact your local dealer for technical support. When the PLL recovers normal operation, the prompt message will disappear, and the Alarm Indicator will go out.
   Caution: Disconnect the power supply before opening the chassis!
