UNIDEN Model uh089sx UHF CB Radio
Introduction
The Uniden uh089sx is designed to provide you with years of trouble free service. Its rugged
components and materials are capable of withstanding harsh environments. Please read this
Operating Manual carefully to ensure you gain the optimum performance of the unit
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.
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
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.
The citizen band radio service is licenced in Australia by ACMA Radio-communications
(Citizen Band Radio Stations) Class Licence and in New Zealand by MED General
User Licence for Citizen Band Radio and operation is subject to conditions contained in
those licenses.
Blackening may occur on the Liquid Crystal Display if the uh089sx 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
operating condition (0-55°C).
