INSTALLATION INSTRUCTIONS
Your new MCB-100 WXD is designed to be installed
in-dash, under/over the dash or anywhere INSIDE your
vehicle. Safety and convenience should be your primary
considerations in deciding exactly where to locate
your CB radio.
CAUTION: Be sure the unit is located where it will
not interfere with the driver or impair access to any
controls necessary for the safe driving of the vehicle.
Before permanently installing the CB radio, connect
the wiring temporarily and make sure it is connected
properly and the CB unit is functioning. (Wiring instruc-
tions for power and antenna are located in this manual).
The radio's power and antenna connecting cables must
be routed and secured in such a manner as not to
interfere with the operation of the brake, accelerator
or other controls. Interference from either the CB unit
or its connecting cables may contribute to the loss of
control of the vehicle.
Hardware is provided for in-dash or under/over dash
installations. Use only the parts included with the CB
unit to ensure proper installation. The use of unautho-
rized parts can cause malfunctions.
In-Dash Installation
In-dash installation requires the following provided
hardware: mounting collar, front faceplate trim ring,
rear metal mounting strap, and microphone hanger
bracket.
4

The in-dash CB unit requires a rear support. Use the
provided metal mounting strap (fig. 4) or a rear
support bushing (not included).
DO NOT remove the factory pre-installed screws
from the sides of the radio (fig. 1). They lock the CB
unit securely into the mounting collar.
fig. 1
1. Before inserting the mounting collar into the dash,
push the side tabs inward with a slight pressure
(fig. 2a). Insert the mounting collar into the dash-
board opening (fig. 2b). Select the proper tabs
according to the thickness of the dashboard material
(fig. 3) and bend them up slightly for a secure hold.

2. Connect power plug, external speaker, and mobile
antenna cable and slide the CB unit into the mounting
collar. The side tabs will expand and lock the CB
unit into place. Secure rear support with provided
metal mounting strap (fig. 4) or use a rear support
bushing (not included).
fig. 4
3. Install the front faceplate trim ring around the face
of the CB unit. Insert the faceplate trim ring tabs into
the grooves on the bottom of the CB unit. Then slide
the top side of the faceplate trim ring back into
position and snap tabs securely into grooves.
4. Mount the microphone hanger bracket wherever it is
most convenient.
Removing the In-Dash CB Unit
1. Remove the front faceplate trim ring by lifting the
tabs on the top of the trim ring out of the grooves in
the CB unit. Then slide the faceplate trim ring down
and off.
