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.

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.

	Blackening may occur on the Liquid Crystal Display. If the UH-090 has been subjected to extreme
NOTE	high temperature (above 60°C). This is not a fault. Normal LCD operation resumes when the
	temperature stabilizes back to standard operating conditions (0 to 55°C).
