Introduction
UNIDEN UH089NB UHF CB Transceiver
Preventive Maintenance
The following system checks should be made every six to twelve months:
• ChecktheStandingWaveRatio(SWR).
• Inspectthetightnessofallelectricalconnections.
• Inspecttheantennacoaxialcableforwearorbreaksontheshielding.
• Inspectthetightnessofallscrewsandothermountinghardware.
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.
NOTE
Blackening may occur on the Liquid Crystal Display if
the UHF CB Radio has been subjected to extreme high
temperature (above 60°C). This is not a fault. Normal LCD
operation resumes when the temperature stabilizes back to
standard operating condition (0-55°C).

Operation
UNIDEN UH089NB UHF CB Transceiver
Think of the squelch control as a gate. If you
turn Squelch fully clockwise it raises the
‘Squelch gate’ so high that no signals get
through.
If you turn the Squelch fully counterclockwise
it lowers the ‘Squelch Gate’ to the extent that
all signals get through - weak, medium and
strong signals and noise.
To set the ‘Squelch Gate’ to the
desired level, turn the squelch knob
counterclockwise until you hear noise.
Then carefully turn the Squelch knob
clockwise until the noise fades. Now only
strong signals get through.
