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:
5

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
7

the ignition switch, such as a spare accessory
terminal in your vehicle's fuse box.
5) Connect the orange (Batt +) wire to your
vehicle's battery positive (+) terminal or to
a point in the vehicle's fuse box that provides
a continuous source of 12 Volts even when
the ignition is turned off. This connection
provides last channel memory feature.
6) Reconnect the cable to the vehicle's battery
negative (-) terminal.
MOBILE ANTENNA INFORMATION
Your Maxon MCB-30 requires a vehicle mount CB
antenna for operation. An antenna is not included
with your MCB-30 because of varying vehicle
applications, individual needs, and owner cost
preferences.
You may use any standard 50 Ohm vehicle mount
CB/weather antenna system with a PL-259 connec-
tor. Maxon antenna model WTA-4WP may be
obtained from your local Maxon CB distributor/
retailer.
NOTE: When installing a mobile antenna, please
follow the antenna manufacturer's installation
instructions completely. Never operate your
CB radio without an antenna or with a broken
antenna cable. This can result in damage to your
CB transmitter circuitry.
•Connect the antenna securely to the unit's
antenna receptacle
8

9
•Mount the antenna as high on the vehicle
as possible - the more the antenna extends
above the roof, the better the reception
•If possible, mount the antenna in the center
of the surface you have chosen
•Keep the antenna cables away from noise
sources such as the ignition system, gauges,
etc.
•Make sure you have a solid, metal-to-metal
ground
ANTENNA TUNING INFORMATION
Most antennas are factory tuned, but performance
can usually be improved by slightly lengthening
or shortening the antenna using a Standing Wave
Ratio (SWR) meter (not included). Refer to the
antenna manufacturer's installation manual for
the exact procedure to tune the antenna. You
can purchase an SWR meter, or have your antenna
checked by your CB Dealer's service department.
OPERATING INSTRUCTIONS
Once you have properly wired your new CB and
connected the antenna, you are now ready to adjust
your radio for optimum reception and voice trans-
mission.
For proper operation, the radio's microphone must
be connected to the unit. Insert the microphone
plug into the microphone jack (MIC). The plug has
a spring loaded locking pin. When inserting the
plug into the jack, push inward until pin is locked
into place. When removing, hold pin in and
withdraw the plug.

10
1) Turn the off/on-volume control clockwise and
adjust to a comfortable volume level.
2) Select the desired CB channel by pressing the
!" button to scroll up or the #button to scroll
down.
3) Adjust the squelch control knob to reduce any
undesirable background noise when no signal
is being received. To do this, select a channel
where no signals are present, or wait until
signals cease on your channel. Then, rotate
the squelch control knob clockwise to a point
where the background noise ceases.
NOTE: When the squelch is set properly, the
speaker will remain quiet until a signal is received.
In order to receive weak signals, do not set the
squelch too high.
To Transmit: Press and hold the push-to-talk bar.
Speak slowly and clearly in a normal voice, two
to three inches from the microphone. When trans-
mitting, the TX LED will glow red.
To Receive: Release the push-to-talk bar.
External Speaker Operation
To connect an optional external speaker, locate
the external speaker jack on the rear of the unit
and insert the speaker plug into the jack. The
radio's internal speaker will be silenced when
an external speaker is engaged.

RADIO COMMUNICATION CODES
Citizens Band radio operators have universally adopted
the "10" Code for standard questions and answers. It
enables them to communicate faster, easier and more
understandably in noisy surroundings.
The following are some of the most common codes and
their descriptions.
When using the code 10-1, you would say, "Ten one",
not "One zero dash one".
