Install the telephone base close to a telephone wall jack and an electrical 
outlet not controlled by a wall switch. The telephone base can be placed on a 
at surface or vertically mounted on the wall (page 13). For optimum range 
and better reception, place the telephone base in a central and  
open location.
If you subscribe to high-speed Internet service (DSL- digital subscriber 
line) through your telephone line, you must install a DSL lter between 
the telephone line cord and the telephone wall jack (page 7). The lter 
prevents noise and caller ID problems caused by DSL interference. Please 
contact your DSL service provider for more information about DSL lters.
Your product may be shipped with a protective sticker covering the handset 
or telephone base display - remove it before use.
