Getting started
If you subscribe to high-speed Internet service (DSL - digital subscriber line) 
through your telephone line, you must install a DSL filter between the 
telephone line cord and the telephone wall jack. The filter prevents noise and 
caller ID problems caused by DSL interference. Please contact your DSL service 
provider for more information about DSL filters.
The telephone base comes ready for tabletop use. If you want to mount your 
telephone on a wall, refer to Wall mount installation on page 7 for details.
