Setup and assembly
The IP Phone KEM mounts on the right side of an IP Phone 2002 or IP Phone 2004 as shown in
Figure 2. It is secured by snapping into a receptacle on the back of the IP Phone using the
desk-mount bracket and structural baseplate supplied with the IP Phone KEM.
The IP Phone KEM connects to the IP Phone 2002 or IP Phone 2004 using the Accessory
Expansion Module (AEM) port on the IP Phone.

Installing the KEM
Use the following instructions to install an IP Phone KEM:
1 Remove the IP Phone from the stand by pressing the IP Phone tilt handle, and pulling the IP
Phone away from the stand.
2 Place the connecting arm of the IP Phone KEM behind the IP Phone and align the IP Phone
KEM connection plug to the AEM port on the back of the IP Phone.
3 Press the IP Phone KEM and IP Phone firmly together until the IP Phone KEM locks into
place.
4 If connecting a second IP Phone KEM, repeat steps 1-3.
5 The second IP Phone KEM is attached to the right side of the first IP Phone KEM.
Note: For the IP Phone 2004, you can also adjust the stand angle to maximum, instead of
removing the stand.
Note: An IP Phone 2002 with the product code NTDU76AB34, NTDU76BB34,
NTDU76AB70, or NTDU76BB70 has shorter connector pins than an IP Phone 2002 with
another product code. If your IP Phone 2002 has a shorter connector pin, you must detach
the ribbon cable connector in the IP Phone KEM from the retaining clip and press the
ribbon cable connector into the header connector before you attach the IP Phone KEM.
