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 UHF CB Radio or
Remote SPK/MIC 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).

Mounting Using the DIN-E Sleeve
If you are unsure about how to install your UH500SX in your vehicle using the DIN-E sleeve,
consult your automobile manufacturer, dealer, or a qualified installer. Before
installing, confirm that your UH500SX fits in the desired mounting area and you have all the
necessary materials to complete the task. Your UH500SX requires a 53 x 183 x 135 mm
mounting area. Allow an additional 60 mm space behind the unit for connectors and wires.
DIN-E Installation (UH500SX, UH500SX-RM Only)
1. Remove the bracket if previously attached.
2. Install the DIN-E sleeve into the opening in your dashboard, lip facing out.
3. Push out the top and bottom tabs to hold the sleeve firmly in place.
4. Remove the flat rubber ring fitted around the cabinet sides near the front of the UH500SX.
Fit the supplied DIN-E rubber ring in it’s place. When fitted the rubber ring will act as a
seal against the DIN-E sleeve. At the left and right sides of the ring there will be a slot space.
The slots in the fitted DIN-E Rubber Ring will enable proper removal of radio from the
DIN-E sleeve.
5. Before inserting the UH500SX in the sleeve, attach the cable from the
previously mounted antenna. Attach the DC Power leads. RED goes to a positive (+)
connection on your fuse block while BLACK connects to the vehicles chassis
ground (-). Be sure all the connections are routed away from any potentially
pinching or slicing sheet metal.
6. Slowly slide the UH500SX into the sleeve until it locks in place.
If you plan to use the Rear MIC Jack or connect an external speaker at a later time,
expect to remove the unit for ease of making those connections.

Removing the UH500SX from the DIN-E Sleeve
If you plan to use the Rear MIC Jack or connect an external speaker, at a later time, you should
plan to remove the UH500SX from the DIN-E sleeve. This is easily done using the provided
Removal Keys.
Fully insert both Removal Keys straight into the slot spaces provided by the DIN-E rubber ring
on the left and the right edges of the radio’s dress panel. You cannot remove the radio if only one
key is available.
Press in fully and the radio will unlock from the sleeve making withdrawal from the
sleeve possible. Store the keys in a safe place for future use.

Connecting the Microphone
FRONT MIC JACK
Push the MIC plug at the end of the microphone into the MIC jack until the connection locks into
place. Gently tug the MIC cord to test that the connection is locked. Use the Front MIC Jack
cover which is threaded onto the MIC cord to seal the MIC jack entry from dust.
Disconnecting the MIC from the Front MIC Jack
Pull away the threaded rubber collar and move it down along the cord. Using the flat blade
of a screwdriver or similar object carefully press the lock tab at the bottom (UH500SX) or left
(UH400SX) side of the MIC plug and push it upwards (UH500SX) or to the right (UH400SX). At
the same time tug on the MIC cord to draw back the MIC plug.
REAR MIC JACK
Use the Rear MIC Jack if the main base is mounted where a front MIC connection is intrusive or
if you wish to use the Remote LCD Speaker MIC with an optional extension cable.
Peel the dust cover from the rear MIC jack. Push the MIC plug at the end of the microphone
into the MIC jack until the connection locks into place. An optional 2m extension cable kit is
available to enable mounting the main base in a hidden location.
The Front and Rear MIC JACKs can not be used at the same time.

Mounting the MIC Hanger
The Microphone Hanger comes in two parts. How and where you mount the MIC hanger will
determine which parts to use.
Conventional Mounting with Screws
Use the front part of the MIC Hanger only.
Locate a suitable mounting position and mark and drill two 3mm holes.
Fix the MIC Hanger into place with screws.
Conventional Mounting with Double Sided Tape (not supplied)
High quality Double-Sided tape can be found at good retail stores.
Secure the front and back pieces of the MIC Hanger using the supplied binding screws.
Locate a suitable mounting position.
Apply high quality Double-Sided tape onto the flat area of the MIC Hanger back piece and then
press firmly to the mounting position.

16
Mounting the MIC Hanger
MIC Hanger mounted over MIC Cable
The curly cord of the Standard MIC and Remote SPK/MIC can extend up to 1.5m.
For practical mounting of the MIC Hanger using the threaded cord technique it is highly
recommended to use this technique with the optional Extension Cable.
Using the second part of the MIC Hanger as a template mark
and drill a single 13mm hole. The hole needs to be large
enough (13mm min) to allow for the MIC plug of the
microphone to fit through.
Feed RJ45 MIC plug through the hole and connect to the
optional Extension Cable. Connect the other end of the
Extension Cable to a MIC Jack on the radio.
Mount the MIC Hanger using the Screw (single part) or
Double Sided Tape (two part) option described on the
previous page, making sure the MIC Hanger is centred over
the hole where the MIC cable is fed through. The single or two
part MIC assembly has a routing cavity to allow fitting over the
MIC cable.

Turning on the Power
Press and hold the ON/OFF control at the
base or the [POWER] button on the Remote
SPK/MIC.
Setting the Manual Squelch (base only)
Turn the outer ring of the SQ control at the base to adjust the Squelch.
You must select a channel which is not in use before setting the SQUELCH control.
(see p.19 for “Selecting a Channel”).
Operation
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.

Setting the Auto Squelch
The Auto Squelch feature is available only when the Remote SPK/MIC is connected. It has an
Off setting and 3 preset squelch levels:
oFF - Auto Squelch OFF
1 - max sensitivity (min squelch)
2 - med sensitivity (med squelch)
3 - min sensitivity (max/tight squelch)
It requires no adjustment.
1. Press [SQL/MON] on the Remote SPK/MIC. The squelch setting flashes.
2. Rotate the channel knob at the base or press on the Remote SPK/MIC to change
the setting. RSQ icon displays when Auto Squelch is active. If tight squelch is
selected SQT icon will also flash.
3. Press [MENU/ENTER] to store the setting.
