TROUBLESHOOTING

We do not expect you to have any problems with your CB, 
but if you do, the following suggestions might help.

If these tips do not solve the problem, do not attempt repairs 
or adjustments yourself. The CB should be serviced only by 
a qualified radio technician. If you still have problems, take 
your CB to your local RadioShack store for assistance.

CARE

Keep the CB dry; if it gets wet, wipe it dry immediately. Use 
and store the CB only in room temperature environments. If 
used in a boat, do not expose CB to extreme heat or cold for 
prolonged periods of time. Handle the CB carefully; do not 
drop it. Keep the CB away from dust and dirt, and wipe it 
with a damp cloth occasionally to keep it looking new.

If your CB is not performing as it should, take it to your local 
RadioShack store for assistance. To locate your nearest 
RadioShack, use the store locator feature on RadioShack's 
website (www.radioshack.com), or call 1-800-The Shack 
(843-7422) and follow the menu options. Modifying or 
tampering with the CB's internal components can cause a 
malfunction and might invalidate its warranty and void your 
FCC authorization to operate it.
