NOTES:

Wall mounting

If there are two separate one-line wall jacks, use two telephone

line cords. Plug one end of the clear telephone line cord into the jack

labeled L1 or L1/L2 on the back of the telephone. Plug one end of

the black telephone line cord into the jack labeled L2 on the back of

the telephone. Route the cords through the channel on the bottom of

the telephone. For line 2 you will need to lift up the bracket and put

the cord through the hole in the bracket. Then, route the cord through

the channel so it comes out at the bottom of the phone and return the

bracket to the wall mount position. Plug the free end of the telephone

line cord for Line 1 into the Line 1 wall jack. Plug the free end of the

telephone line cord for Line 2 into the Line 2 wall jack. Make sure the

telephone line cords snap firmly into place at both ends. Place the

telephone on the wall mounting plate and pill down until it is held

securely.
