Installing a Line Filter or DSL Filter A telephone line filter or DSL filter prevents services that use the phone line from causing interference on your phone. To get a line filter, contact your service provider or look in an electronics store. Plug the filter into the telephone wall jack and plug the base into the filter. Make a test call to make sure the noise is gone. Liquid Damage CAUTION: If the base is covered in liquid, disconnect the adapter & phone cord from the wall before touching it. If the liquid is only on the exterior housing of the base or handset, wipe it off and use as normal. If you can hear liquid inside the housing: 1. Remove all compartment covers, and disconnect all cables and cords. 2. If liquid is leaking from any vent or hole, turn the phone so that vent faces down. If not, place the largest vent face down. 3. Let dry for at least 3 days. Check for liquid inside the phone before replacing compartment covers & reconnecting cords. Resetting Handsets If you have trouble with a handset or if you want to replace one, clear the registration information from the base and the handset: 1. Press & hold END/CLEAR and # at the same time until you see the System Reset menu. 2. If you still have the base the handset is registered to, select Deregister HS, then select the handset you want to reset. If you don't have that base anymore, select Base Unavailable. 3. To confirm, select Yes. The handset displays Handset not registered. Registering Handsets If you see a "not registered" message on a handset, you must register it to a base before using it. 1. Place the handset in the base; the display should say Handset Registering. 2. Wait until the display says Registration Complete (about 30 seconds), then pick up the handset and press HOME/FLASH. 3. If you don't hear a dial tone or the display says Registration Failed, charge the battery completely, then try again. 22 - English
