CARE AND MAINTENANCE
Your RadioShack PRO-91 150-Channel Handheld
Trunking Scanner 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 immediately. Liquids can contain
minerals that can corrode the electronic
circuits.
Use only batteries of the recommended
size and type. Always remove old and
weak batteries. They can leak chemicals
that destroy electronic circuits.
Handle the scanner gently and carefully.
Dropping it can damage circuit boards
and cases and can cause the scanner to
work improperly.
Use and store the scanner only in normal
temperature environments. Temperature
extremes can shorten the life of electron-
ic devices, damage batteries, and distort
or melt plastic parts.
Keep the scanner away from dust and
dirt, which can cause premature wear of
parts.
Wipe the scanner with a damp cloth oc-
casionally to keep it looking new. Do not
use harsh chemicals, cleaning solvents,
or strong detergents to clean the scan-
ner.
Modifying or tampering with the scanner’s internal com-
ponents can cause a malfunction, invalidate your scan-
ner’s warranty and void your FCC authorization to
operate it. If your scanner is not operating as it should,
take it to your local RadioShack store for assistance.
