Telephone installation
Connect the telephone line cord(s) and the power cord to the telephone base.
If you subscribe to high speed Internet service (DSL - digital subscriber line)
through your telephone line, you must install a DSL filter between each
telephone line cord and 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.
Option 1: If you have a two-line wall jack, install your telephone base as
shown below.
2.
Plug the other end of the
coiled handset cord into the
jack at the left side of the
telephone base.

of the power adapter
into the power jack
on the back of the
telephone base.

black telephone line
cord (4-conductor)
into the jack labeled
LINE 1/L1+L2 on
the back of the
telephone base.
Plug the other end of the black
telephone line cord (4-conductor)
into the wall jack.
Plug the large
end of the power
adapter into an
electrical outlet
not controlled by
a wall switch.
If you have DSL high
speed Internet service, a
DSL filter (not included)
is required. The DSL filter

telephone wall jack.
