Installation Overview The information below is an overview for installing the repeater and auxiliary equipment. Unpack and inspect the equipment. Perform a pre-installation function check test of the equipment, and configure parameters. Pay particular attention to environmental conditions at the site, ventilation requirements, and grounding and lightning protection. Install the equipment at the site.
You may customize repeater parameters such as TX/RX frequency, TX power and signalling, according to user needs. After configuration of parameters is complete, you may perform site installation. Installation Requirements 1. Environmental Conditions at Intended Installation Site The repeater may be installed in any location suitable for electronic communication equipment, provided that the environmental conditions do not exceed the equipment specifications for temperature, humidity and air quality.
air to enter and exit. If several repeaters are installed in a single cabinet, ensure ventilation openings surrounding each repeater allow for adequate cooling. All cabinets must have at least 10cm of open space between the air vents and any wall or other objects.
Installation Steps You will need a Philips screwdriver (cross head screwdriver), a Torx (T10) screwdriver and a spanner, to install the repeater. Caution: Be sure to observe proper electrostatic discharge precautions if any part must be removed from the repeater. The installation steps are as follows: 1. Mount the repeater in a rack, bracket or cabinet. 2. Connect accessories such as antenna cables and power cords to the repeater.
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 heatsink, remove all power, data and RF cables from the PA, and finally remove the PA heatsink. 5. Mount the duplexer, and fasten the 2 screws inside the housing and on the side panel respectively. Then mount the PA heatsink, and connect all the lines and cables.
Ensure RF cables are properly connected between the duplexer and RF connectors.
Screws RF cables Screws Duplexer Mounted with Front Side Facing Downwards Electrical Connections After the repeater has been mechanically installed, electrical connections must be made. This involves making the following connections: DC power cord Antenna cables See the rear panel view for the positions of connectors. Power Supply Connections 1. Ground Connection The repeater is equipped with a ground screw located on the rear panel. Connect ground wires to the screw. 2.
The repeater may be connected to a regulated DC power supply or a backup battery. The DC source or battery backup system is connected to the repeater through the DC power inlet at the rear of the repeater (see rear panel view). Caution: Before you make the connection, ensure the DC power supply or battery backup system is capable of supplying a minimum of 200W, and check if the DC power supply has current limit.
2. Antenna Selection The selection of antenna is also critical to system performance. The selected antenna must be 50 Ohm impedance and capable of at least 50W. High gain antennas may be used to increase system coverage. Please take note of licensing restrictions when selecting high gain antennas. Some services or regions may have antenna gain or system radiation limitations. The antenna must be connected to the duplexer with a high grade 50 Ohm transmission line (e.g. Andrew HELIAX cables).

Over Temperature Alarm When temperature of the PA module exceeds the normal range, the Alarm Indicator will glow red and the LCD will display the prompt below: Then the repeater will disallow transmission, and you will need to: 1. Check if the surface temperature of PA heatsink exceeds 80℃. If yes, implement the following steps 2 and 3 to locate the failure. Caution: The PA heatsink can become extremely hot at this moment, so DO NOT touch the repeater.
prompt below: Then the repeater will automatically switch to low TX power, to protect the transmitter from overheating. You will need to: 1. Check if the fan is blocked by any solid object. If yes, please remove it. 2. If you cannot solve the issue, please contact your local dealer for technical support. When the fan recovers normal operation, the LCD prompt will disappear, and the Alarm Indicator will go out.
result in poor transmitting performance, and even damage to the transmitter. 2. Check if connection between the transmitter and RF or antenna cables is loose or lost. If yes, please secure the connection or replace the cables. 3. If you cannot solve the issue, please contact your local dealer for technical support. When the VSWR falls within the normal range, the LCD prompt will disappear, and the Alarm Indicator will go out.
Low Voltage Alarm Over Voltage Alarm Then the repeater will automatically shut off, but the LCD prompt will remain. You will need to: 1. Use a voltmeter to check if the input voltage of DC power supply is normal, especially if the voltage will run below the normal range while transmitting. If yes, please replace the DC power supply or backup battery. 2. Check if connection between the repeater and the DC power cord is loose or lost. If yes, please secure the connection or replace the cable. 3.
