Powering Your CB Radio
You can power your CB radio from one of these four sources:
• The rechargeable Ni-MH battery pack
• Eight AA batteries (not included) using the supplied battery
case
• AC power using an AC-to-DC power supply (not included)
• Vehicle power using a DC power cord (not included)
Using the Ni-MH Battery Pack
Charge the Ni-MH battery pack (using the supplied AC charger)
for about 18 hours prior to using it for the first time. Afterward,
it takes 14-16 hours to charge the battery pack when it is fully
discharged.
You can charge the battery pack while it is installed or removed.
But the CB radio does not work during charging.
To charge the battery pack:
Connect the AC Charger to the
CHG Jack, then plug it into an AC
outlet. The CHARGE Indicator
lights red and charging starts.
Note: The supplied AC charger
is for charging only, not for
directly powering the CB.
To install the battery pack:
Latch
Slide the battery pack onto the
CB radio until it clicks. The battery
pack fits onto the CB radio only
one way. Do not force it.

the AC charger to a ceiling outlet. After charging, disconnect
the AC charger.
You must use a Class 2 power supply that provides 16V DC
and delivers at least 200mA. The barrel plug’s center must
be positive and the barrel plug must fit the CB’s CHG jack.
The supplied AC charger meets these specifications. Using
an adapter that does not meet these specifications could
damage the CB radio or adapter.
Always connect the AC charger to the battery pack before
you connect it to an AC outlet, and disconnect the AC
charger from the AC outlet before you disconnect it from the
battery pack.
Overcharging your battery pack could shorten its life.
Do not charge your battery pack at temperatures below 14°F
(–10°C) or above 131°F (55°C).
You cannot recharge the Ni-MH battery pack using DC
power.
Recycle Rechargeable Batteries
Placing rechargeable batteries into the trash or the municipal
waste system can be harmful to the environment and may be
illegal in your area. RadioShack participates in an industry
program to collect and recycle rechargeable batteries at the end
of their useful life.
You can return your rechargeable batteries to your local
RadioShack store for recycling (at no cost to you). Or call
1-800-THE-SHACK (1-800-843-7422) for information on
rechargeable battery recycling in your area. RadioShack’s
involvement in this program is part of the
company’s commitment to preserving our
environment and conserving our natural
resources.

Safety Precaution
Your wireless hand-held portable transceiver contains a low
power transmitter. When the Push-to-Talk (PTT) button is
pushed it sends out radio frequency (RF) signals. The device is
authorized to operate at a duty factor not to exceed 50%. In
August 1996, the Federal Communications Commissions (FCC)
adopted RF exposure guidelines with safety levels for hand-held
wireless devices.
To maintain compliance with the FCC’s RF exposure guidelines
hold the transmitter and antenna at least 1 inch (2.5 centimeters)
from your face and speak in a normal voice, with the antenna
pointed up and away from the face. If you wear the handset
on your body while using the headset accessory, use only the
supplied belt clip for this product and when transmitting, take it
out of the belt to ensure that the antenna is at least 1 inch (2.5
centimeters) from your body.

Understanding Digital Weather Alert
The weather service precedes each weather alert with a digitallyencoded SAME (Specific Area Message Encoding) signal, then
a 1050 Hz tone. When your local weather station broadcasts
a weather alert signal, the CB radio sounds an alert tone and
displays a message showing the alert level.
SAME Event Code
Alert Tone
Message
A (Watch)
Watch alert
10 seconds
WCH (Watch)
W (Warning)
TOR (Tornado)
SVR (Severe)
S (Statement)
RWT (Test)
Warning alert
10 seconds
WRN (Warning)
Statement alert
10 seconds
ADV (Advisory)
Notes:
• The CB radio does not display the actual location referenced
by SAME messages. It uses only the message portion of the
SAME signal.
• If severe weather threatens, do not wait for an alert tone;
tune to the weather broadcast and monitor the weather
information.
• If a weather signal ends, the CB radio beeps three times
(when the key tone is turned on) and only when the weather
signal ends the first time, then WX flashes to indicate there is
no signal.

Transmission Courtesy
• Wait for a pause in someone else’s transmission before you
ask for a break.
• If you do not receive an answer to your call after a second
attempt, sign off and wait several seconds before trying again.
• Do not hold down PTT when you are not talking. (This is
called dead keying.)
• Assist callers with directions, information about road
conditions, and any other reasonable requests.
Transmission Range
The maximum range and quality of CB transmissions vary
depending on the following conditions:
14
21-1679A_En_111207.indd 14
11/12/2007 17:32:58
• Type and quality of the antenna.
• Height of the antenna’s mounting location (the higher the
antenna, the better the signal’s range).
• Surrounding terrain (mountains and tall buildings limit the range).
• Weather conditions.
• Number of nearby CBs operating on the same channel.
Note: Your CB radio’s transmission range is generally line-ofsight. To ensure maximum range, always keep the battery
pack fully charged or use fresh batteries.
