CARE AND MAINTENANCE
Your RadioShack 200-Channel VHF/UHF/Air Handheld Scan-
ner is an example of superior design and craftsmanship. The
following suggestions will help you care for your scanner so you
can enjoy it for years.
Keep the scanner dry. If it gets wet, wipe it dry immedi-
ately. Liquids might contain minerals that can corrode
the electronic circuits.
Use and store the scanner only in normal temperature
environments. Temperature extremes can shorten the
life of electronic devices and distort or melt plastic
parts.
Keep the scanner away from dust and dirt, which can
cause premature wear of parts.
Handle the scanner gently and carefully. Dropping it
can damage circuit boards and cases and can cause
the scanner to work improperly.
Wipe the scanner with a damp cloth occasionally to
keep it looking new. Do not use harsh chemicals,
cleaning solvents, or strong detergents to clean the
scanner.
Modifying or tampering with the scanner’s internal components
can cause a malfunction and might invalidate its warranty and
void your FCC authorization to operate it. If your scanner is not
performing as it should, take it to your local RadioShack store
for assistance.
