Concertmate (420-4020) Care and Maintenance Faxback Doc. # 7654 Your Radio Shack Concertmate-1000 is an example of superior design and craftsmanship. The following suggestions will help you care for the keyboard so you can enjoy it for years. Keep the keyboard dry. If it gets wet, wipe it dry immediately. Some liquids contain minerals that can corrode the electronic circuits. Use only fresh batteries of the recommended size and type. Always remove old or weak batteries. They can leak chemicals that destroy electronic circuits. Handle the keyboard gently and carefully. Dropping it can damage circuit boards and cases and can cause it to work improperly. Use and store the keyboard only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts. Keep the keyboard away from dust and dirt, which can cause premature wear of parts. Wipe the keyboard with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean it. Modifying or tampering with the keyboards internal components can cause a malfunction and might invalidate the keyboard's warranty and void your FCC authorization to operate it. If your keyboard is not performing as it should, take it to your local Radio Shack store for assistance. (br/all-9/29/94)
