WIRING

Refer to Chapter 3, Sectlon 4, Checkout and Failure Isolation, for instructions for testing the system wiring and components for possible failure.

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.

1.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.

2.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.

3.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.

4Insert 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.

5. To remove the station, lift up to unsnap both screws or studs from the bottom housing, and iii the station away from the wall.
