Telephone base installation

Install the telephone as shown below. Choose a location where the telephone
is not exposed to excessive heat, cold, dust or moisture.
If you subscribe to high-speed Internet service (digital subscriber line - DSL)
through your telephone lines, you must install a DSL filter between the
telephone base 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.
1. Plug one end of the telephone
line cord into the telephone
jack at the back of the
