Table/desk 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 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. Install the telephone
as shown below.
NOTE: For Handset
installation, please see page 12.
1. Write your telephone number
on the THIS NUMBER label
on the telephone base.
2. Plug one end of the
telephone line cord into the
telephone line jack at the
bottom of the telephone
base.
3. Thread the cord through
the channel and out of the
telephone as shown.
4. Connect the other end to a
modular telephone wall jack.
