4 INSTALLATION PROCEDURES
This section presents the steps necessary for installing the radio and connecting it to associated equip-
ment. After completing these steps, the radio is ready for in-service operation.
4.1 Unpacking and Inspection
Check the contents against the packing list secured to the outside of the shipping box. Accessories and
spare parts kits, if any, are wrapped separately. Inspect all items for signs of damage. Save all packing
materials in case you need to ship the radio in the future.
4.2 Installation Steps
The radio should be installed in a relatively clean, dust-free environment that allows easy access to the
connectors and indicators. Air must pass freely over the rear heat sink and around the unit for proper
cooling. Follow the steps below to install the unit and prepare it for initial startup.
1 Mount the Unit. The unit may be rack-mounted (2U high) in a 19-inch rack cabinet, or may be placed
on any sturdy tabletop or other flat surface. The installation site should be free of excessive dust, and
should have adequate ventilation. The chassis should be positioned so that all interface cabling will
reach the required connectors.
When rack mounting, the rack ears can be installed in one of three positions to allow flexibility in the
mounted depth of the chassis. The unit should be mounted so as to maximize airflow around the rear
heat sink.
2 Ground the Chassis. Use the ground screw provided at the rear panel to connect the radio to a safety
ground (NEC Class 2 compliant), which bonds the Master Station, antenna system, and connected data
equipment to a single-point ground. Keep all ground leads as short as possible.
3 Connect Antenna Feedlines. All coaxial antenna connections are made to the Type-N connectors on
the rear of the unit. The number of connections depends on options ordered, including duplexer options,
as follows: Separate TX and RX; Combined TX/RX; wired for an external notch filter with RX Out,
RX In and combined TX/RX.
