CARE AND MAINTENANCE

To enjoy your RadioShack PRO-70 50-Channel Portable Scanner for a long time:

Keep the scanner dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that can corrode the electronic circuits.

Use only fresh batteries of the recommended size and type. Always remove old and weak batteries. They can leak chemicals that de- stroy electronic circuits.

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

Use and store the scanner only in normal tem- perature environments. Temperature ex- tremes 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 occasion- ally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong deter- gents to clean the scanner.

Modifying or tampering with the scanner’s internal compo- nents can cause a malfunction and might invalidate its 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.
