Pocket Tone Dialer (430-0145) Care and Maintenance Faxback Doc. 3 15951 The Radio Shack Pocket Tone Dialer is an example of superior design and craftsmanship. The following suggestions will help you care for the dialer so you can enjoy it for years. Keep the dialer dry. If it gets wet, wipe it dry immediately. Liquids might contain minerals that can corrode the electronic circuits. Use and store the dialer only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts. Handle the dialer gently and carefully. Dropping it can damage circuit boards and cause the dialer to work improperly. Keep the dialer away from dust and dirt, which can cause premature wear of parts. Wipe the dialer with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the dialer. Use only fresh batteries of the required size and type. Always remove old or weak batteries. They can leak chemicals that can destroy electronic circuits. Modifying or tampering with the dialer's internal components can cause a malfunction and might invalidate its warranty. If the dialer is not performing as it should, take it to the local Radio Shack store for assistance. (TE/all-07/18/95)
