INSTALLATION INSTRUCTIONS
Your new MCB-30 is designed to be installed
under the dash or anywhere inside your vehicle.
It can be mounted horizontally or vertically. Safety
and convenience should be your primary consider-
ations in deciding exactly where to locate your
Maxon MCB-30 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. The radio's power or
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
it's connecting cables may contribute to the loss
of control of the vehicle.
Installing the MCB-30:

Mechanical Mounting
1) Determine the mounting location of your
MCB-30.
2) Use the CB cabinet mounting bracket as a
template for marking the location of the screw
holes when mounting the CB under the dash,
or at another selected location.
3) Drill the necessary holes and secure the
mounting bracket with the self-tapping
screws provided.
CAUTION: EXTREME CARE SHOULD BE
EXERCISED WHEN DRILLING UP INTO
THE DASH to avoid any damage to in-dash
electronic ignition wiring, cruise control,
instruments or accessory wiring.
4) Position the CB unit between the mounting
bracket arms (in line with the retention knobs).
Set the CB unit angle for the best operating
comfort and control accessibility. Tighten the
two retention knobs to secure the CB unit in
place.
5) Install the microphone hanger bracket utilizing
the pre-drilled mounting holes in the MCB-30
cabinet, or attach the bracket to the vehicle
dash or another convenient location.
6) If you choose to mount the CB in a location
where self-tapping screws cannot be used,
determine the most secure method of fastening
the CB cabinet.

Power Supply Connection
The MCB-30 is designed for 12V DC operation in
vehicles with NEGATIVE (-) GROUND electrical
systems. Most domestic and foreign made cars and
trucks use a negative ground system. NOTE: If your
negative (-) battery terminal is connected to the
motor block of your vehicle, it is a negative ground
system.
CAUTION: Do not attempt to connect your
MCB-30 to a POSITIVE (+) ground vehicle
as damage may occur to the CB unit and/or
to your vehicle's electrical system.
NOTE: Check your vehicle's ground requirements
before you begin the installation!
Your MCB-30 should be connected using the
following steps:
1) Move the off/on-volume control to the "off"
position. CAUTION: If the off/on-volume
control is in the "on" position without an
antenna hook-up, it could result in damage
to the transmitter circuitry.
2) Disconnect the cable from your vehicle
battery's negative (-) terminal.
3) Connect the black GROUND wire to a metal
part of your vehicle's frame.
NOTE: Be sure the metal part is not insulated from
the vehicle's frame by a plastic part.
4) Connect the red (to switched accessory) wire
to a source of voltage that turns on and off with
