CARE AND MAINTENANCE
Your RadioShack PRO-90 300-Channel TrunkTracker
Scanner is an example of superior design and crafts-
manship. 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 min-
erals that can corrode the electronic cir-
cuits.
Use only rechargeable batteries of the rec-
ommended 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 electronic
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 occa-
sionally 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 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.
