the clear cord into the jack labeled L1 or L1/L2 on the back of the telephone.
Then, plug the other end into the wall jack for Line 1. Plug one end of the black
line cord into the jack labeled L2 or DATA on the back of the telephone base.
Then, plug the other end into the wall jack for Line 2. Make sure the telephone
line cord are plugged firmly into the telephone base and the wall jack.
L2 or DATA
NOTE: This product is designed to operate optimally with two telephone lines.
If you choose to install only one telephone line, the telephone will continue to
operate normally as long as the unused line is not selected. If you experience diffi-
culty, make sure you have pressed the correct LINE button.
1. Connect the line cords to the
telephone and wall jacks.
2. Plug one end of the handset cord
into the handset. Plug the other
end into the jack on the left side
of the telephone base.
3. To determine which line is in
use, press LINE 1 and call one
of the telephone numbers. If
there is a busy signal, Line 1 is
the number you called. If Line
2 rings, it is the number you
called.
