Your RadioShack 40 Channel Mobile CB is a 
great way to communicate with other CB 
radio operators. You can mount it in a vehicle 
for mobile use, or in your home for use as a 
base station.

Your CB has these advanced features:

LCD display with EL backlight on display 
and controls
 — lets you see the CB’s 
operating status at a glance and helps you 
easily see the display and controls when you 
use the CB at night.

Digital Compass — aids navigation on the 
road.

Emergency Channel One Touch Access 
— lets you quickly switch to Channel 9 or 19 
so you can monitor or report emergency 
situations.

3 Channel Memories — let you easily 
access your favorite channels.

Last Channel Recall (RCL) — Lets you 
quickly recall the last channel used.

Dual Channel Controls — let you tune the 
channel from the transceiver or the 
microphone.

RF Gain Control — lets you adjust the 
receiver’s gain to match the strength of the 
signal.

Phase-Locked Loop (PLL) Frequency 
Synthesizer
 — provides highly accurate and 
stable tuning.

Two Built-In Ceramic Filters — ensure 
superior channel selectivity and freedom 
from adjacent channel interference.

Automatic Modulation Control — prevents 
the transmitter signal from over-modulating 
and distorting.

Automatic Noise Limiter — reduces 
impulse-type noises while receiving.

Built-In PA (Public Address) Amplifier — 
lets you use your CB as a public address 
system when you add an optional PA 
speaker.

Universal Mounting Bracket — lets you 
mount your CB securely in your vehicle.

Note: To use this CB, you must connect a 
mobile or base station antenna. Your local 
RadioShack store has a wide variety of 
antennas. For more information, see 
“Connecting an Antenna” on Page 4.

FCC INFORMATION

The Federal Communications Commission 
(FCC) does not require you to have a license 
to operate this CB radio. However, you must 
know Part 95 of 

FCC Rules. It explains the 

proper operation of a Class D citizen’s band 
transceiver. We enclosed a copy of Part 95 
with your CB radio.

Warning: Do not open the CB radio to make 
any internal adjustments. A CB radio is set 
up to transmit a regulated signal on an 
assigned frequency. It is against the law to 
alter or adjust the settings inside the unit to 
exceed these limitations.

To be safe and sure:

• Never open your CB radio’s case.

• Never change or replace anything in 

your CB radio.
