PREPARATION  
INSTALLING/REPLACING THE  
BATTERY  
Your walkie-talkie uses one 9 volt battery (not sup-  
plied) for power. For the longest life and best perfor-  
mance, we recommend you use an alkaline battery  
such as RadioShack Cat. No. 23-553.  
Caution:  
Use only a fresh battery of the required  
size and recommended type.  
Follow these steps to install a battery.  
1. Slide the battery compartment cover in the  
direction of the arrow to remove it.  
Fig. 1  
2. Snap the battery onto the battery connector  
inside the compartment. The connector only  
fits on the battery one way.

3. Replace the cover.  
When the BATTERY LOW indicator lights, replace  
the battery.  
Cautions:  
• Always remove an old or weak battery. Batter-  
ies can leak chemicals that can destroy elec-  
tronic parts.  
• Dispose of old batteries promptly and properly.  
Do not bury or burn them.

CARE AND MAINTENANCE  
Your RadioShack TRC-509 FM Walkie-Talkie is an  
example of superior design and craftsmanship. The  
following suggestions will help you care for your  
walkie-talkie so you can enjoy it for years.  
Keep the walkie-talkie dry. If it gets  
wet, wipe it dry immediately. Liquids  
might contain minerals that can cor-  
rode the electronic circuits.  
Use and store the walkie-talkie only in  
normal temperature environments.  
Temperature extremes can shorten  
the life of electronic devices, damage  
batteries, and distort or melt plastic  
parts.  
Keep the walkie-talkie away from dust  
and dirt, which can cause premature  
wear of parts.  
Handle the walkie-talkie gently and  
carefully. Dropping it can damage cir-  
cuit boards and cases and can cause  
the walkie-talkie to work improperly.

Use only a fresh battery of the required  
size and recommended type. Batteries  
can leak chemicals that damage your  
walkie-talkie’s electronic parts.  
Wipe the walkie-talkie with a damp  
cloth occasionally to keep it looking  
new. Do not use harsh chemicals,  
cleaning solvents, or strong deter-  
gents to clean the walkie-talkie.  
Modifying or tampering with the walkie-talkie’s inter-  
nal components can cause a malfunction and might  
invalidate your walkie-talkie’s warranty and void  
your FCC authorization to operate it. If your walkie-  
talkie is not performing as it should, take it to your lo-  
cal RadioShack store for assistance.

THE FCC WANTS YOU TO KNOW  
Your walkie-talkie might cause TV or radio interfer-  
ence even when it is operating properly. To deter-  
mine whether your walkie-talkie is causing the  
interference, turn off your walkie-talkie. If the inter-  
ference goes away, your walkie-talkie is causing it.  
Try to eliminate the interference by:  
• Moving your walkie-talkie away from the  
receiver.  
• Contacting your local RadioShack store for  
help.  
If you cannot eliminate the interference, the FCC re-  
quires that you stop using your walkie-talkie.
