PREPARATION  
INSTALLING  
BATTERIES  
Your radio requires three AAA bat-  
teries for power. For the best per-  
formance and longest life, we  
recommend RadioShack batteries.  
Cautions:  
• Use only fresh batteries of the  
required size and recommend-  
ed type.  
• Do not mix old and new batter-  
ies, different types of batteries  
(standard, alkaline, or re-  
chargeable), or rechargeable  
batteries of different capacities.  
1. Rotate VOLUME/OFF fully coun-  
terclockwise to turn off the ra-  
dio, then slide the battery  
compartment cover off in the  
direction of the arrow.  
5
 
21-1825.fm Page 6 Friday, March 3, 2000 12:2 PM  
2. Slide CHARGE ON/OFF inside  
the battery compartment to  
OFF (for alkaline batteries) or  
ON (for Ni-Cd or Ni-MH re-  
chargeable batteries).  
3. Install three AAA batteries ac-  
cording to the polarity symbols  
(+ and –) marked inside.  
4. Slide the battery cover back  
on.  
When the batteries weaken, two  
beeps sound and the radio will not  
transmit or receive and  
appears.  
When this happens, replace the  
6
 
21-1825.fm Page 7 Friday, March 3, 2000 12:2 PM  
batteries. To ensure maximum  
range, keep fresh batteries in the  
radio.  
Warning: Dispose of old batteries  
promptly and properly. Do not burn  
or bury them.  
Caution: If you do not plan to use  
the radio for a month or longer, re-  
move the batteries. Batteries can  
leak chemicals that can destroy  
electronic parts.  
RECHARGING  
NI-CD OR NI-MH  
BATTERIES  
Warning: Do not attempt to charge  
alkaline batteries. Non-recharge-  
able batteries can get hot or ex-  
plode if you try to recharge them.  
7
 
21-1825.fm Page 8 Friday, March 3, 2000 12:2 PM  
If you use rechargeable Ni-Cd or  
Ni-MH batteries, you can recharge  
them in the radio using an optional  
AC or DC adapter (both available  
from your local RadioShack store).  
The radio’s CHRG jack is only for  
charging Ni-Cd or Ni-MH batteries.  
Connecting an adapter will not  
power the radio.  
You can recharge Ni-Cd or Ni-MH  
batteries inside the radio using a  
6V, 60 mA AC or DC adapter and a  
size H Adaptaplug® (neither sup-  
plied). Both adapters and Adapta-  
plugs are available at your local  
RadioShack store.  
Cautions:  
You must use  
Class power  
source that supplies  
a
2
!
6V DC and delivers at least 60  
mA. Its center tip must be set  
to positive and its plug must fit  
8
 
21-1825.fm Page 9 Friday, March 3, 2000 12:2 PM  
the radio's CHRG jack. Using  
an adapter that does not meet  
these specifications could  
damage the radio or the adapt-  
er.  
• Always connect the adapter to  
the radio before you connect it  
to an external power source  
(such as an AC outlet or a ve-  
hicle cigarette-lighter socket).  
When you finish, disconnect  
the adapter from power source  
before you disconnect it from  
the radio.  
To connect an adapter to the radio,  
follow these steps.  
1. Rotate VOLUME/OFF fully coun-  
terclockwise to turn off the ra-  
dio, then slide the battery  
compartment cover off in the  
direction of the arrow.  
2. Set CHARGE ON/OFF to ON.

21-1825.fm Page 10 Friday, March 3, 2000 1:32 PM  
3. Attach the Adaptaplug to the  
adapter so TIP reads positive  
(+).  
4. Connect the charger’s barrel  
plug to the radio’s CHRG jack  
and plug its other end into a  
standard AC outlet or a vehicle  
cigarette-lighter socket.  
5. Complete charging takes about  
15 hours. When charging is  
complete, unplug the AC  
adapter from the AC outlet,  
then disconnect it from the  
CHRG jack.  
Note: Ni-MH batteries take  
longer to charge than Ni-Cd  
batteries.

QUIET CODES  
Quiet codes let you talk and listen  
to people who are using other radi-  
os set to the same channel and qui-  
et code. This is like having a sub-  
channel within a channel, giving  
you greater communication flexibili-  
ty. When you set a quiet code  
(there are 38 to choose from) and  
turn on this feature, you can com-  
municate with anyone who has a  
radio set to the same channel and  
code.  
1. Hold down QUIET until QUIET  
appears and the quiet code  
flashes.  
14  
 
21-1825.fm Page 15 Friday, March 3, 2000 1:32 PM  
2. Repeatedly press (or hold  
down) 8 or 9 until you see  
the code number you want to  
use. (See the “Quiet Codes”  
chart on Page 16 for a com-  
plete list of quiet codes.)  
3. Press QUIET to store the code.  
4. To turn on the quiet code fea-  
ture, press QUIET. QUIET ap-  
pears. To turn off the feature,  
press QUIET until QUIET dis-  
appears.  
Note: We recommend that you se-  
lect a quiet code in the range 7–30.  
If you select a code below or above  
that range, you must wait 1 to 2  
seconds after holding down PUSH  
TO TALK before you start talking.

FCC INFORMATION  
Important: Do not open your radio  
to make any internal adjustments.  
Your radio is set up to transmit a  
regulated signal on one of 14 as-  
signed frequencies. It is against the  
law to alter or adjust the settings in-  
side the radio to exceed those limi-  
tations. Any adjustments to your  
radio must be made by a qualified  
technician using the proper test  
equipment.  
To be safe and sure:  
• Never open your radio’s case.  
• Never change or replace any-  
thing in your radio except the  
batteries.  
Your radio might cause TV or radio  
interference even when it is operat-  
ing properly. To determine whether  
your radio is causing the interfer-  
21  
 
21-1825.fm Page 22 Friday, March 3, 2000 1:32 PM  
ence, turn it off. If the interference  
goes away, your radio is causing it.  
Try to eliminate the interference by:  
• moving your radio away from  
the receiver  
• calling your local RadioShack  
store for help  
If you cannot eliminate the interfer-  
ence, the FCC requires that you  
stop using the radio.  
This device complies with Part 15  
of the FCC Rules. Operation is sub-  
ject to the following two conditions:  
(1) This device may not cause  
harmful interference, and (2) this  
device must accept any interfer-  
ence received, including interfer-  
ence that may cause undesired  
operation.
