Water Resistant (630-5014) Care and Maintenance Faxback Doc. # 16343 Stopwatch Use and store the stopwatch only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts. Handle the stopwatch gently and carefully. Dropping it can damage the circuit boards and can cause it to work improperly. Keep the stopwatch away from dust and dirt, which can cause premature wear of parts. Wipe the stopwatch 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 recommended size and type. Always remove an old or weak battery. It can leak chemicals that can destroy electronic circuits. Modifying or tampering with the stopwatch's internal components can cause a malfunction and might invalidate its warranty. If your stopwatch is not performing as it should, take it to your local Radio Shack store for assistance. (ALL-08/04/95)
