and possibly damage the equipment.
Turn the base of the phone upside down so that
the phone base can be mounted parallel to
the wall—and then place it back on the base.
Replace the four mounting screws.
Insert the phone cord through the center of the
stand and plug it into the WHITE jack on the
bottom of the phone. Plug the other end into
the modular wall jack.
Mount the phone on the wall plate using the
screw keyholes on the base of the stand. For
proper mounting, the wall pIate must be an
AT&T 630B connecting block.
Connect the handset cord as described in “Desk
Mounting” Step 1A, and label the button sheet
as in Steps 3A and 3B.
Connecting and Testing Telephones

To connect a phone, plug the modular telephone
mounting cord into a modular wall jack or directly into a
206 module extension jack. (If you are connecting a
standard phone and its mounting cord is loose, use an
AT&T D2R mounting cord instead.)
To install two phones (or other devices) on a single
extension jack, see “Combination Extensions” earlier in
this guide.

phones only) a test pattern should appear on
the display. (If not, call for support as
instructed on the inside front cover of this
guide.)
Replace the handset; the phone is now in normal
operating mode.
