Getting started
Telephone base installation
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 will prevent noise 
and caller ID problems caused by DSL interference. Please contact your DSL 
service provider for more information about DSL filters.
Install the telephone base as shown below.
