information
2Available frequencies & channels
are within 400-520MHz Band only
in 12.5kHz steps. Police, Fire &
Ambulance reception is unencrypted
analogue.
3AVS - Automatic Volume Stabilizer
detects and manages incoming
audio to comparable levels.

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.

DIN Installation
Mounting Using the DIN Bracket
If you are unsure about how to install your UH9050 in your vehicle using the DIN
bracket, consult your automobile manufacturer, dealer, or a qualied installer. The DIN
bracket is made up of a sleeve and a frame.
Before installing, conrm that your UH9050 ts in the desired mounting area and you
have all the necessary materials to complete the task.

BEZEL
FRONT FRAME

DIN Installation
13
UNIDEN UH9050 UHF CB Transceiver
Installing the DIN Bracket
1. Remove the front frame if previously attached.
2. Install the DIN sleeve into the DIN slot of your dashboard and secure it by bending
the top and bottom folding tabs.
3. Slide the front frame into the UH9050. Ensure the threaded holes on UH9050 line up
with holes on the front frame.
4. Secure UH9050 onto the side of the front frame using 2 pieces of 6mm screws.
5. Attach the DC power leads to UH9050 and your vehicle. RED goes to a positive (+)
connection on your fuse block while BLACK connects to the vehicle chassis ground
(-).
6. Attach the antenna cable, rear MIC and rear speaker to the back of UH9050 if using.
7. Make sure all the connections are routed away from any potentially pinching or
slicing sheet metal.
8. Slowly slide the front frame (with UH9050 attached and all cable connections done)
into the DIN sleeve until it locks in place.
9. Install the bezel on the radio.
NOTE
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 UH9050 from the DIN Sleeve
If you plan to use the Rear MIC Jack at a later time, you should plan to remove the
UH9050 from the DIN sleeve. This is easily done using the provided Removal Keys.
Remove the Bezel before fully insert both Removal Keys straight into the slots 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.
REMOVAL KEYS
REMOVAL KEYS

Connecting the Microphone
Front MIC Jack
Remove the MIC cover using a at blade screwdriver. 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 threaded rubber
collar 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 at
blade of a screwdriver or similar object carefully press the lock tab at the bottom of the
MIC plug and push it upwards. 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.

UNIDEN UH9050 UHF CB Transceiver
NOTE
The unit will not function if connected to two Remote LCD Microphones
(optional RM-980) at the same time.

Mounting the MIC Hanger
16
UNIDEN UH9050 UHF CB Transceiver
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 at area of the MIC Hanger
back piece and then press rmly to the mounting position.
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.

17
UNIDEN UH9050 UHF CB Transceiver
MIC Hanger mounted over MIC Cable
NOTE
The curly cord of the Remote LCD Speaker MIC can extend up to 2m.
For practical installation of the MIC Hanger mounted over MIC Cable use
this method with the Extension Cable.
The plug of the extension cable connects to the Radio. The socket end of the extension
cable connects with the microphone plug.
1. The rubber collar (dust cover) on the microphone cable is not required and can be
cut away or pushed out of the way along the cable.
2. Drill a 13mm hole at the MIC hanger location.
3. Thread the microphone plug through the hole and connect with the extension cable.
4. Mount the MIC Hanger over the hole and cable.
5. At the Radio: Connect the extension cable plug to the MIC Jack. Fit the rubber
bushing over the MIC jack.

Mounting the MIC Hanger

Turning on the Power
Press and hold PWR/VOL control at the base or the [POWER] button on the optional
Remote SPK/MIC.
NOTE
Low-Voltage/High-Voltage Alert
The UH9050 can operate on 12VDC (13.8V) or 24VDC (27.6V) power
supply, with the range between 10.2VDC to 28.8VDC.
If the power supply voltage exceeds 28.8VDC, an alert tone sounds and
HI DC ashes for 5 seconds. The power source must not exceed 32VDC
otherwise permanent damage may occur to your radio, which may not be
covered by the manufacturer’s warranty.
If the input voltage falls below 10.2VDC, LO DC ashes for 5 seconds. The
power turns off automatically if voltage falls below 9.0VDC.
Switch your UH9050 OFF and disconnect it from the power source, before
locating the cause of the power supply problem.
