When you choose an antenna, keep in
mind that, for the best performance, you
should mount the antenna:
• as high as possible on your vehicle,
home or building
• as far as possible from sources of
electrical noise
• vertically
Once you choose an antenna, follow its
mounting instructions. Then route the
cable to the CB and connect the cable to
ANTENNA on the back of the CB.
Cautions:
• Avoid routing the cable next to sharp
edges or moving parts which might
damage the cable.
• Do not run the cable next to power
cables or other radio antenna
cables.
• Do not run the cable through a vehi-
cle’s engine compartment or other
areas that produce extreme heat.
To take advantage of your radio’s maxi-
mum range, adjust the antenna’s Stand-
ing Wave Ratio (SWR) using an SWR
meter available at your local Ra-
dioShack store.
Follow the instructions supplied with the
SWR meter and antenna to adjust your
antenna’s SWR to the lowest possible
value. SWR values of 2.0:1 are general-
ly acceptable, with readings of 1.5:1 or
lower being more desirable.
CONNECTING THE
MICROPHONE
1. Press the plastic tab on the top of
the supplied microphone’s plug and
align the 5-pin DIN microphone plug
with the corresponding pin holes in
the CB’s MIC jack. Then push the
plug into the mic jack.
2. Slide the microphone onto the
microphone holder.
To disconnect the microphone from the
CB, press the plastic tab on the side of
the plug, then pull out the plug.
Caution: Never pull on the microphone
cable.

USING VEHICLE BATTERY
POWER
Follow these steps to connect the CB to
vehicle battery power.
1. Connect the red wire (with in-line
fuse holder) to a point in your vehi-
cle’s fuse block that has power only
when the ignition is in the ACC or
ON position.
2. Connect the black wire to a metal
part of the vehicle’s frame (chassis
ground).
Caution: Do not connect the black
wire to a non-metallic (plastic) part,
or to any part insulated from the
vehicle’s chassis by a non-metallic
part.
USING THE CB AS A
BASE STATION
Although this CB radio is designed
mainly for mobile use, you can also use
it as a base station with an AC power
source. For base station installation, you
need these items:
• a 13.8V DC power supply that can
supply at least 1.5 amps — available
from RadioShack.
Caution: Most 13.8V DC power
supplies plug into a standard AC
outlet to produce DC power. Before
connecting your CB to a 13.8V DC
power supply, read and follow the
instructions included with the power
supply.
• base station antenna — available
from RadioShack.
• coaxial antenna cable and connec-
tor — available from RadioShack.
Warning: Use extreme caution when
you install or remove a base station CB
antenna. If the antenna starts to fall, let it
go! It could contact overhead power
lines. If the antenna touches the power
line, contact with the antenna, mast, ca-
ble or guy wires can cause electrocution
and death. Call the power company to
remove the antenna. Do not attempt to
remove it yourself!
