							For Home Use (Desktop Installation)
1. Insert the DC plug end of the AC Adapter into the DC
13.8V jack on the rear panel.
2. Plug the AC Adapter into a standard 120V AC wall outlet.
3. Plug the Telescoping Antenna into the ANT connector.
Extend the antenna to its full height. For frequencies 
higher than 406 MHz, shortening the antenna may improve
the reception.
4. Use the desktop stand for a better viewing and operating
angle.
Helpful Hints
•If strong interference or electrical noise is received, relocate
the scanner or its antenna away from the source.
•If you are operating the scanner in a fringe area or need to
improve reception, use an optional antenna designed for
multi-band coverage. (You can purchase this type of 
antenna at a local electronics store.)
•If the optional antenna has no cable, use 50-70 ohm coaxial
cable for lead-in. A mating plug may be necessary for the
optional antennas.
For Mobile Use (In-Car Installation)
Installation for Temporary Use:
A Cigarette Lighter Power Cord is provided for easy, 
temporary installation.
Warning:Do not use the cigarette lighter power cord in a 
positive ground vehicle.
Plug one end of the Cigarette Lighter Power Cord into the 
cigarette lighter jack and the other end into the DC 13.8V jack
on the back of the scanner.

Installing the BC350C
UB317Z (BC350C) 0916  9/16/03  12:42 PM  Page 8 
						

							Connecting the Antenna Plug
Connect the mobile antenna plug into the ANT connector on
the rear panel. (For more information on antenna installation,
please refer to the instruction guide that came with your
antenna.)
Mounting the Radio for Everyday Use
The BC350C can be mounted using the mounting bracket
(optional).
This bracket is available from the Uniden parts department
(see page 5)
1. Select an ideal location in your vehicle to mount the
BC350C. Avoid a location that could interfere with your
driving. In a passenger car, the ideal location is underneath
the dashboard on the passenger side.
2. Use the mounting bracket (optional) as a template for
marking the location of the mounting screws.
Note: If there are screws already holding the dashboard, you
can use the same screw holes to mount the bracket.
3. Drill the necessary holes and secure the mounting bracket
in place using the screws provided.
4. Mount the radio to the bracket only after the wiring has
been connected to the rear panel.
Connecting the Power Cord
Note:If you are not experienced in connecting accessories to
the vehicle fuse box, please see your automotive dealer for
advice on proper installation.
Installation for Everyday Use:
1. Check the vehicle battery connections to determine which
battery terminal (positive or negative) is grounded to the
engine block or chassis. Most of today’s vehicles use a
negative ground. If your vehicle has a negative ground, 
follow Steps 2 and 3. Otherwise, skip to the note following
Step 3.
2. Connect the RED wire of the DC power cord to the 
accessory contact in your vehicle’s +13.8 VDC fuse box.
3. Connect the BLACK wire of the DC power cord to the 
negative side of the vehicle (usually the chassis).
Note:In vehicles with a positive ground, the RED wire
connects to the chassis and the BLACK wire connects to
the 
accessory contact in the fuse box.
4. Insert the DC plug into the DC 13.8V jack on the back of
the scanner.
