REJ RECORDING JACK
Using the REJ Recording Jack
Use the REJ Recording Jack to connect a telephone to an external
tape recorder or speaker. There are two versions of the REJ record-
ing jack. The REJ P/N 92265 can only be connected to a Super
Display Telephone (P/N 92663 or 92283x), while P/N 80175 (for the
i-Series phones) can be connected to 28- or 34-Button i-Series
phones. The REJ output is a standard RCA jack which you can con-
nect directly to an AUX level input on a recorder or page amplifier.
Installing the REJ (Figures 4-22 - 4-26)
CAUTION
Be sure the connected audio device provides a standard AUX
level input.
The handset is alwaysrecording, even when the handset is
idle and in the cradle. This may result in recording undesiredconversations.
To connect the REJ Recording Jack:
1. Turn the telephone upside down and remove the four screws
from each corner of the telephone set.
2. Lift the upper housing off of the telephone base.
3. On the side of the lower housing, use a blunt object to remove
the plastic molding that covers the hole for the REJU connector.Figure 4-22  PUNCHING OUT FOR THE REJ

WALL-MOUNT KIT
Using the Wall-Mount Kit
Any key telephone can be equipped with a wall-mount kit for
attachment to a wall. The wall-mount kit includes a mounting
bracket, wall-mount screws, washer, and handset hangers. Each

you may also be able to install the bracket on the phone so that
the phone can be placed on the desk. This angles the phone to
provide easier viewing of the keys and the display.
Note:The wall-mount kit currently does not accommodate
installing on an AT&T wall plate.
