Selection of a frequency pair is done by rotating the rotary selector switch on top of the radio. See Table 1 for a listing of the Air Test transmit and receiver frequencies, and transmitter power output levels associated with the rotary selector switch.
- Page 12 2. PERFORMANCE CHECKS IN AIR TEST MODE Tables 3 and 4 outline a series of performance checks that can be done without any disassembly of the radio. If there is an indication of a malfunction, these checks should be the first step in the fault isolation process. The FCC requires that the frequency and deviation of the transmitting device be checked before the device is placed in service and once annually thereafter.
