Telephone base installation
If you have a 2-line wall jack, install the telephone base as shown in
Figure One: Installation with 2-line jack on below.
If you have separate wall jacks for each line, install the telephone base as
shown in Figure Two: Installation with separate line jacks on page 3.
Make sure that the electrical outlet is not controlled by a wall switch.
If you subscribe to digital subscriber line (DSL) high-speed Internet service
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. Contact your DSL service
provider for more information about DSL ﬁlters.
