INSTALLATION INSTRUCTIONS
Mechanical Mounting
CAUTION: Be sure the unit is mounted 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 and/or antenna
connecting cables must be routed and secured so
that they do not 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.
1) Use the power/antenna connector box as a
template for marking the location of screw
holes (self-tapping screws provided).
2) Drill the necessary holes and secure the
power/antenna connector box with the
self-tapping screws.
NOTE: EXTREME CARE SHOULD BE EXERCISED
WHEN DRILLING UP INTO THE DASH to avoid
damage to in-dash electronic ignition wiring, air
bag or air bag sensors, cruise control, instruments
or accessory wiring.
3) If you choose to mount the power/antenna
connector box under the vehicle seat or at an
alternate location where self-tapping screws
cannot be used, determine the most secure
method of fastening the power/antenna
connector box. Use strong mounting tape,
plastic tie wraps, etc.
4) Use the three included screws to mount the
transceiver hanger bracket onto the vehicle's
dash.

5) To connect an optional external speaker, locate
the external speaker jack on the power/antenna
connector box and firmly insert the speaker
plug into the jack. The radio speaker will be
disconnected when the external speaker is
engaged.
DC Power Supply Connection
The MCB-10A is designed for 12V DC operation
in vehicles with NEGATIVE (-) electrical systems.
Most domestic and foreign-made vehicles use a
negative ground system.
NOTE: Check your vehicle's ground requirements
before you begin radio installation. If the battery
terminal marked negative (-) is connected to the
motor block of your vehicle, it is a negative ground
system.
CAUTION: DO NOT attempt to connect the
MCB-10A to a positive (+) ground vehicle. Doing
so may cause damage to the CB unit and to your
vehicle's electrical system.
Connecting the MCB-10A Power Cord
1) Make sure the off/on-volume control is in the
off position before proceeding.
2) Remove the fuse located in the MCB-10A DC
power cord. To do this, grasp each end of the
white fuse casing, push together and twist the
ends away from one another.
3) Connect the red lead wire of the DC power
cord to a positive (+) 12V DC source, either
the engine fuse block, the internal fuse box, or
directly to the positive (+) post of your battery.
7

8
Usually the internal fuse box is the most
convenient connecting point. You may wish
to connect the red lead wire to the accessory
terminal on the engine fuse block or in the
ignition switch so your CB radio will automati-
cally turn off when the ignition is disengaged,
preventing any accidental battery drainage.
4) Connect the black lead wire to the metal
chassis of the vehicle. For the best connection,
remove any paint from the grounding point. A
good, direct metal-to-metal ground is essential
for best performance.
5) Replace the fuse into the white casing on the
MCB-10A DC power cord.
Antenna Installation
Your Maxon MCB-10A requires a mobile mount
antenna for operation. Because of varying vehicle
applications, individual needs and owner cost
preferences, an antenna is not included with
your MCB-10A.
Maxon's model WTA-4WP mobile mount antenna
may be obtained from a local Maxon CB distributor,
or you may use any standard 50 Ohm mobile mount
CB antenna with a PL-259 connector.
NOTE: Please carefully follow the antenna manu-
facturer's installation instructions. Never operate
your CB radio without an antenna or with a broken
antenna cable. Doing so could cause internal
damage to the CB circuitry. Always:
•Connect the antenna securely at the antenna
receptacle of the unit.
• Mount the antenna as high on the vehicle as

9
possible - the more the antenna extends above
the roof, the better the reception will be.
•If possible, mount the antenna in the center of
the chosen surface.
•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
Most antennas are factory tuned. However, radio
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 tuning procedure. You can
purchase an SWR meter or have your antenna
checked by your CB Dealer's service department.

OPERATING INSTRUCTIONS
1) Turn the power on and adjust to a comfortable
volume level.
2) Select any one of the 40 channels by pressing
the channel up/down buttons.
3) Adjust the squelch control knob to reduce
any undesirable background noise. 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 clock-
wise to a point where the background noise
ceases.
When the squelch is set properly, the speaker will
remain quiet until a signal is received. Do not set
the squelch too high, or you will not be able to
receive weaker signals.
To Transmit: Hold the transceiver microphone area
2-3 inches from your mouth and press the push-to-
talk (P-T-T) bar located on the side of the transceiver.
Speak into the microphone slowly and in a normal
tone of voice. When transmitting, the TX LED will
glow.
To Receive: Release the push-to-talk bar.

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".
