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.
Make necessary electrical and cabling connections, including the following:
- DC power cord
- Coaxial cables to TX and RX antennas (if you use two antennas)
Perform a post-installation function check test of the equipment, to verify proper installation. Before Installation Before you install the repeater at the site, you are suggested to power on the repeater and check it for proper operation. 1. Applying Power Before applying power to the repeater, make sure the voltage of DC power supply or battery is compliant with the operating voltage range of the repeater. Then connect the DC power supply or battery to supply power to the repeater. 2. Verifying Proper Operation Operation of the repeater can be indicated by the 8 LEDs located on the front panel. After proper operation is verified, you can configure parameters for the repeater. Caution: Some repeater components can become extremely hot during operation. Turn off all power and wait until the repeater is sufficiently cool before touching the repeater. 3. Configuring Parameters 7 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.
Operating Temperature
-30 to +60 This is the temperature measured in close proximity to the repeater. For example, if the repeater is mounted in a cabinet, the temperature within the cabinet is measured.
Humidity Humidity conditions should not exceed 95% relative humidity @ 50C.
Air Quality For equipment operating in an area which is environmentally controlled and with the repeater rack mounted, the airborne particle level must not exceed 25g/m3. And for equipment operating in an area which is not environmentally controlled and with the repeater cabinet mounted, the airborne particle level must not exceed 90g/m3. Caution: If the repeater is to be installed in an area which is usually dusty, dirty, or does not meet the air quality requirements, then the air used to cool the repeater modules must be treated using appropriate filtering devices. Dust or dirt accumulated on the internal circuit boards and modules is not easily removed, and can cause malfunctions such as overheating and intermittent electrical connections. 2. Equipment Ventilation The PA heatsink is equipped with a cooling fan used to provide forced convection cooling. When planning the installation, observe the following ventilation guidelines:
Customer supplied cabinets must be equipped with ventilation slots or openings for 8 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.
When multiple cabinets (each equipped with several repeaters) are installed in an enclosed area, ensure appropriate ventilation and consider air conditioning or other climate control equipment, to satisfy the temperature requirements stated above. 3. Equipment Installation Methods The RD980 repeater may be mounted in a rack, bracket or cabinet, and may be placed on your desk. 4. Site Grounding and Lightning Protection Caution: Proper site grounding and lightning protection are vitally important considerations. Failure to provide proper lightning protection may result in permanent damage to the repeater. The ground and lightning protection system is one of the most important considerations when designing a communication site. Proper grounding techniques and lightning protection are closely related, and the general category of site grounding may be divided into the following two sections:
Electrical Ground Ground wires carrying electrical current from circuitry or equipment at the site are included in the category of electrical ground. Examples include the AC and DC power used to source equipment located at the site, and wires or cables connected to alarms or sensors located at the site.
Lightning Ground Providing adequate lightning protection is critical to a safe reliable communication site. The repeater is equipped with a ground screw located on the rear panel. This screw is used to connect the repeater to the site grounding. All antenna cables, and AC and DC power cords, should be properly grounded and lightning protected by following the rules and guidelines provided in the above sections. 9 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. If a duplexer needs to be mounted If the repeater needs to work with a duplexer, your will need to implement the following installation steps prior to the above steps 1 and 2. 1. Loosen the three screws on the bracket with a Philips screwdriver. 2. Install the optional duplexer and the bracket. Be sure to observe the specifications of the two antenna connectors on the duplexer, to determine which connector should be connected to the transmitter. Ensure the antenna connector connected to the transmitter is beside the rear panel of the repeater. Take Hytera supplied duplexer as an example. If the transmitter is connected to the low cavity connector, the duplexer should be mounted with the front side facing upwards (see the following figure on the left); and if it is connected to the high cavity connector, the duplexer should be mounted with the front side facing downwards (see the following figure on the right). 10 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. 11 Ensure RF cables are properly connected between the duplexer and RF connectors. TX signal:

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. DC Power Supply or Battery Backup Connection 13 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. Since high current consumption is required for transmitting, improper setting of the current limit may cause transmission failure. Caution: The repeater is to be connected to a battery that is in accordance with applicable electrical regulations for the end use country. If battery power is exhausted, you are recommended to charge the battery with an external charger. Remove the battery from the repeater when charging. RF Antenna Connections TX and RX antennas are connected to two separate connectors (shown in the rear panel view), and there must be adequate isolation of 75 dB UHF or 85 dB VHF between them. If only one antenna through a duplexer is connected, at least 75 dB UHF or 85 dB VHF isolation between the TX and RX antenna ports is required. Caution: Please ensure that all power is switched off before disconnecting the TX antenna. 1. Duplexer Selection The selection of duplexer is critical to system performance. The use of a notch (band reject) duplexer is possible in some systems that are not located at high RF density sites. If the repeater is used in high RF density sites, the use of a pass-notch duplexer is recommended. The duplexer must be able to handle at least 50W continuously. For the best system performance, the insertion loss should be less than 2dB. 14 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). The line must have connectors to match the connectors on the duplexer and antenna. Caution: It is important that all antenna cables are grounded at the point they enter the building. All aspects of the antenna design must comply with the relevant local regulations. Post-Installation Checklist After the repeater has been mechanically installed and all electrical connections have been made, power may now be applied and the repeater should be checked for proper operation. 1. Applying Power Before applying power to the repeater, make sure all boards are securely seated in the appropriate connectors on the rear panel and all RF cables are securely connected. Turn on the DC power source to supply power to the repeater. 2. Verifying Proper Operation Operation of the repeater can be indicated by the 8 LEDs located on the front panel and also by LCD prompts. Caution: Some repeater components can become extremely hot during operation. Turn off all power and wait until the repeater is sufficiently cool before touching the repeater. 15 Status Indications LCD Icons The LCD of your repeater displays the repeater status and menu items.
