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-talki e 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 cor­rode the electr onic circuits.

Use and store the walkie-t alkie 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 cir­cuit boards and cases and can cause
the walkie-talkie to work improperly.

9

Use only a fresh battery of the required
size and rec ommended 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 deter­gents to clean t he walkie-talkie.

Modifying or tampe ring with the walkie- talki e’s in ter­nal component s can cause a malfunct ion and might
invalidate your walkie-talkie’s warranty and void
your FCC authorization to operate it. If your walkie­talkie is not perf orming as it shoul d, take it to your l o­cal RadioShack st ore for assistance.

THE FCC WANTS YOU TO KNOW

Your walkie-talkie might cause TV or radio interfer­ence even when it is operating properly. To deter­mine whether your walkie-talkie is causing the
interf erenc e, turn off y our wa lkie- talkie . If th e inter ­ference goes away, your walkie-talkie is causing it.
Try to eliminate the i nterference by:

• Moving your walkie-talkie away from the

receiver.

• Contacting your local RadioShack store for

help.

If you cannot elim inat e the interf erence , t he FCC re­quires that you stop using your walkie-talkie.
