Power Supply Co ectio
The MCB-45W 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 (-) attery terminal is connected to the
motor lock of your vehicle, it is a negative ground
system.
CAUTION: Do ot attempt to co ect your
MCB-45W to a POSITIVE (+) grou d vehicle
as damage may occur to the CB u it a d/or to
your vehicle's electrical system.
NOTE: Check your vehicle's ground requirements
efore you egin the installation!
Your MCB-45W should e connected using the
following steps:
1) Move the off/on-volume control to the "off"
position. CAUTION: If the off/o -volume
co trol is i the "o " positio without a
a te a hook-up, it could result i damage
to the tra smitter circuitry.
2) Disconnect the ca le from your vehicle
attery'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 ot i sulated 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
the ignition switch, such as a spare accessory
terminal in your vehicle's fuse ox.

5) Connect the ora ge (Batt +) wire to your
vehicle's attery positive (+) terminal or to
a point in the vehicle's fuse ox 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 ca le to the vehicle's attery
negative (-) terminal.
MOBILE ANTENNA INFORMATION
Your Maxon MCB-45W requires a vehicle mount
CB antenna for operation. An antenna is not included
with your radio ecause of varying vehicle applica-
tions, individual needs, and owner cost preferences.
Maxon antenna model WTA-4WP may e o tained
from your local Maxon CB distri utor / retailer or
you may use any standard 50 Ohm vehicle mount
CB/weather antenna with a PL-259 connector.
NOTE: When installing a mo ile antenna, please
follow the antenna manufacturer's installation
instructions completely. Never operate your CB
radio without a a te a or with a broke a te a
cable. This can result in damage to your CB trans-
mitter circuitry.
•Connect the antenna securely to the radio's
antenna receptacle.
•Mount the antenna as high on the vehicle as
possi le - the more the antenna extends a ove
the roof, the etter the reception. If possi le,
mount the antenna in the center of the surface.
•Keep the antenna ca les away from noise sources
such as the ignition system, gauges, etc.
•Make sure you a have solid, metal-to-metal
ground.

ANTENNA TUNING INFORMATION
Most antennas are factory tuned, ut performance
can usually e improved y 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 y
your CB Dealer's service department.

USING THE WEATHER CHANNELS
The National Weather Service uses several special
radio frequencies to provide continuous reports of
local weather conditions and forecasts throughout
the United States. Taped weather messages are
repeated every four to six minutes on a 24-hour

asis and are routinely revised every one to three
hours, or more frequently if needed.
During severe weather, the routine weather road-
casts will e interrupted with special weather
warning messages.
The MCB-45W is designed to receive all of these
special weather frequencies plus three international
marine frequencies. A NOAA Weather Radio
Network Frequency card is enclosed to identify
the frequencies specifically roadcast for your
geographical area. The MCB-45W receives CB,
National Weather Service and international marine
weather roadcast frequencies as listed:
CB Cha els 1 - 40 (26.965 - 27.405 MHz)
Weather Cha el 01 WX 162.550 MHz
