2.1.1 SCOPE OF INSTRUCTIONS

Since each installation is somewhat unique, the following installation instructions are intended only as a general guide to installing this transceiver.

2.1.2 PERFORMANCE TESTS

Although each transceiver is carefully tested at the factory before shipment, it is good practice to ver- ify proper operation before it is placed in service. Important checks are receiver sensitivity and transmit- ter frequency, deviation, and power output.

2.1.3 TRANSCEIVER PROGRAMMING

The transceiver needs to be programmed before it is placed in service. Programming instructions are located in Section 4. Transceivers normally contain

factory test channels and other test parameters when they are shipped. The included labels should be attached to the option keys to indicate the function.

2.1.4 POWER SOURCE

This transceiver must be connected to a nominal 12 VDC, negative ground vehicle electrical system (negative battery terminal connected directly to the chassis). If the vehicle has some other type of electri- cal system, a suitable voltage converter is required.
