Troubleshooting

Memory Backup

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 all other mounting hardware.

Should the unit malfunction or perform poorly, follow these procedures:

Check the power cord and fuse.

Check the VOLUME control setting. Be sure the SQUELCH is adjusted properly. Possibly the radio is

over squelched.

Check that the transmission line (coaxial cable) is securely connected to the ANTENNA connector.

Check that the antenna is fully extended for proper operation.

Check that all transmission line (coaxial cable) connections are secure and free of corrosion.

A built in EEPROM protects the channels stored in the uh088sx memory after the DC power cable is

disconnected
