Preventive Maintenance: The following system checks should be made every six to twelve months:
Check the Standing Wave Ratio(SWR)
Inspect the tightness of all electrical connections.
Inspect the antenna coaxial cable for wear or breaks on the shielding
Inspect the tightness of all screws and other mounting hardware.
Troubleshooting: Should the unit malfunction or perform poorly, follow these procedures;
If the transceiver is completely inoperative
Check the power cord and fuse.
If there is trouble with receiving
Check the VOLUME control setting. Be sure the SQUELCH is adjusted properly. Possibly the radio is over
squelched.
