The following suggestions will help you care for your metal detector so you can enjoy it for years. Handle the metal detector gently and carefully. Dropping it can damage circuit boards and cases and can cause the metal detector to work improperly. Use and store the metal detector only in normal temperature environments. Temperature extremes can shorten the life of electronic devices and distort or melt plastic parts. Wipe the metal detector with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the metal detector. The coil is waterproof and can be submerged in either fresh or saltwater. Be careful to prevent water from entering the chassis. After using the coil in saltwater, rinse it (the coil) with fresh water to prevent corrosion of the metal parts. Modifying or tampering with the detector's internal components can cause a malfunction and might invalidate your detector's warranty. If your detector is not performing as it should, take it to your local Radio Shack store for assistance. (JC/all-11/02/95)
