4.0 INSTALLATION PROCEDURES

This section presents the steps necessary for installing the radio and connecting it to associated
equipment. 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. Accesso-
ries 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.
The rear heat-sink will get hot under continuous or high duty-cycle transmission. Use caution
handling the unit while in operation.
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 posi-
tioned so that all interface cabling will reach the required connectors.
a. 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 ra-
dio 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 or-
dered, 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.
