STATION WALL MOUNTING
No conversion is required to prepare a digital
telephone to be hung on the wall. Two keyhole
shaped slots are available on the bottom housing
which enable a digital telephone to be either mounted
directly on a wall using two, 
#lo, panhead screws
(obtained locally), or mount on a wall jack cover plate.
if mounted using a wail jack cover plate, an AT&T
type 6308 wail plate is recommended for best
results.

If #lO screws are used, thread them into the wall
within 
l/8-inch of the surface. Refer to Figure 6-l
for the spacing dimensions.
Turn the telephone over and remove the plastic tab
that is molded into the housing. It is located at the
lower right-hand comer of the housing.
Position the keyhole shaped holes in the bottom of
the station over the 
#lO screws or the cover plate
studs. Slide the station down until a slight click is
fett.
Insert the plastic tab that was removed from the
lower housing in step 2 into the handset 
cavity.
This tab provides a secure retention for the handset
when it is hung up.
To remove the station, lift up to unsnap both screws
or studs from the bottom housing, and iii the
station away from the wall.
