To take full advantage of the phone’s capabilities, you must
have two phone lines with separate phone numbers. If you
have only one line, you can order a second from your phone
company.

You can connect the phone to the lines in one of three
ways:

• connect two lines through a two-line modular phone

jack

• connect two lines through two one-line modular phone

jacks

• connect one line through a one-line modular phone

jack.

Your telephone connects directly to a modular telephone
line jack. If your telephone wiring does not have a modular
jack, you can update the wiring yourself using jacks and
adapters (available at your local RadioShack store or online
at RadioShack.com), or have the telephone company
update the wiring for you. You must use compatible modular
jacks that are compliant with Part 68 of FCC Rules.

Connecting to Phone Lines

The line that connects a two-line
phone jack to the phone
company wiring must be
twisted-pair cable. Otherwise,
you might hear interference
(crosstalk) between the two
lines.

The USOC number of the two-
line jack to be installed is RJ14C
(RJ14W for a wall-plate). The
USOC number of a single-line
jack is RJ11C.

On a Desk Top

If you connect the phone to a
two-line phone jack with a two-
line cord, do not connect a cord
to the TEL LINE 2 jack or the
phone will not operate properly.
Instead, you can connect
another phone device, such as
a fax machine or modem.

If you connect the phone to a
single one-line phone jack,
avoid pressing the unused line
button or you might hear
feedback.

You must use a Class 2
power source that supplies
9V AC and delivers at least

350 mA. Its center tip must be set
to positive and its plug must fit the
phone's DC IN 9V jack. The
supplied adapter meets these
specifications. Using an adapter
that does not meet these
specifications could damage the
phone or the adapter.

Always connect the AC adapter
to the phone before you
connect it to AC power. When
you finish, disconnect the
adapter from AC power before
you disconnect it from the
phone.
