Introduction
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 radio 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 radio ts in the desired mounting area and you have
all the necessary materials to complete the task.

DIN Installation
11
UNIDEN PRO5050 AM-CB Transceiver
Installing the DIN Bracket
1. Remove the 4 front mounting screws to separate the front frame from the DIN
sleeve.
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 PRO5050 into the front frame. Ensure the threaded holes on PRO5050 line
up with holes on the front frame.
4. Secure PRO5050 onto the front frame using 4 pieces of 6mm screws.
5. Attach the DC power leads to PRO5050 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 PRO5050 if
using.
7. Make sure all the connections are routed away from any potentially pinching or
slicing sheet metal.
8. Slide the front frame (with PRO5050 attached and all cable connections done) back
into the DIN sleeve and secure it using 4 front mounting screws.
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.

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 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.
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.
