Introduction

NOTE

Blackening may occur on the Liquid Crystal Display if the UH013 has been subjected to extreme high
temperature (above . This is not a fault. Normal LCD operation resumes when the temperature
stabilizes back to standard operating conditions (0 to 55°C).

60°C)

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.
