HS-149 (430-0192) Care and Maintenance Faxback Doc. # 9708 The HS-149 Telephone Headset is an example of superior design and craftsmanship. The following suggestions will help you care for the headset so you can enjoy it for years. Keep the headset dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that can corrode the electronic circuits. Use and store the headset only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts. Handle the headset gently and carefully. Dropping it can damage circuit boards and cases, and can cause the headset to work improperly. Keep the headset away from dust and dirt, which can cause premature wear of parts. Wipe the headset 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 fresh batteries of the required kind and type. Modifying or tampering with the headset's internal components can cause a malfunction and might invalidate its warranty. If your headset is not operating as it should, take it to your local Radio Shack store for assistance. If the trouble is affecting the phone lines, the phone company might ask you to disconnect the headset until you have resolved the problem. (LB/all-02/24/95)
