CARE AND MAINTENANCE

Your RadioShack PRO-72 50-Channel Portable 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 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 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.

Handle the scanner gently and carefully. Dropping it can damage circuit boards and cases and can cause the scanner to work improperly.

Use only fresh batteries of the required size and type. Batteries can leak chemi- cals that damage your scanner’s elec- tronic 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.
