PRO-27 20-Channel Programmable Scanner (200-0507) Care and Maintenance Faxback Doc. # 31200 Your new Radio Shack PRO-27 20-Channel Direct-Entry Programmable 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 fresh batteries of the required 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 occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the scanner. Modifying or tampering with your scanner's internal components can cause a malfunction and might invalidate the scanner's warranty and void your FCC authorization to operate it. If your scanner is not operating as it should, take it to your local Radio Shack store for assistance. (SP 3/12/96)
