MAINTENANCE AND ADJUSTMENT
This transceiver is especially designed for the environment encouuntered in mobile
installations. The use of all solid state circuitry and its light weight result in high
reliability. Should failure occur, however, replace parts only with identical parts. Do
not substitute.
PREVENTIVE MAINTENANCE
At six to twelve month intervals, the following system checks should be made:
1. Check Standing Wave Ratio (SWR).
2. Inspect all electrical connections to ensure that they are tight.
3. Inspect antenna coaxial cable for wear or breaks on shielding.
4. Inspect all screws and other mounting hardware for tightness.
ADJUSTMENT
This transceiver is factory aligned and should not require any adjustment when used
with a 52 ohm antenna. If an antenna other than 52 ohm impedance is used,
adjustment of the transmitter output circuit may be made to obtain optimum power
transfer to the antenna. This adjustment should be made only by a licensed techni
cian using a high quality in-line RF wattmeter which will not produce standing waves
when inserted in the antenna cable.
