CARE AND MAINTENANCE

Your RadioShack 200Ch VHF/Air/UHF Home Scanner is an example of superior de- sign and craftsmanship. The following suggestions will help you care for your scan- ner 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 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 mal- function and might invalidate its warranty and void your FCC authorization to oper- ate it. If your scanner is not performing as it should, take it to your local RadioShack store for assistance.
