The following suggestions will help you care for your mixer so you can enjoy it for years. Keep the mixer dry. If it gets wet, wipe it dry immediately. Liquids might contain minerals that can corrode the electronic circuits. Use and store the mixer only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, and distort or melt plastic parts. Keep the mixer away from dust and dirt, which can cause premature wear of parts. Wipe the mixer with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean it. Use only a fresh battery of the required size and type. Always remove an old or weak battery. It can leak chemicals that can destroy electronic circuits. Modifying or tampering with the mixer's internal components can cause a malfunction and might invalidate its warranty. If your mixer is not performing as it should, take it to your local Radio Shack store for assistance. (LB-10/18/95)
