Care and Maintenance

Notice

If the UH-099 has been subjected to extreme high .temperature (above 60°C) for a prolonged period of time, blackening of the Liquid Crystal Display (LCD) may occur. This is not a fault. Normal LCD operation resumes when the temperature stabilises back to proper operating conditions (0 to 55°C).

Preventive Maintenance

The following system checks should be made every six to twelve months:

1.Check the Standing Wave Ratio (SWR).

2.Inspect the tightness of all electrical connections.

3.Inspect the antenna coaxial cable for wear or breaks on the shielding.

4.Inspect the tightness of all screws and other mounting hardware.

Troubleshooting

Should the unit malfunction or perform poorly, follow the procedures indicated below:

1.If the transceiver is completely inoperative ...

*Check the power cord and fuse.

2.If there is trouble with receiving ...

*Check the VOLUME control setting.

*Be sure the SQUELCH is adjusted properly. Possibly the radio is over- squelched.

*Check that the radio is in an operational mode.

3.If there is trouble with transmitting ...

*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.

Memory Backup

A built-in capacitor protects the channels stored in the SUNDOWNER UH-099 memory for up to 2 weeks after the DC power cable is disconnected.
