the cord for the DSS 4450 out the back of the telephone, and the handset
and headset cords out the front of the telephone or out the channel on the
side of the telephone.
If the telephone will be wall mounted by using the optional wall-
mounting stand, you must run the headset and handset cords out
the channel on the side of the telephone.
The 4424LD+ telephone and the DSS 4450 cannot be wall
mounted.
If the telephone does not work properly after all cords are
connected, check to be sure that the satin-silver D4BU line cord
and the clear D2R line cords are connected properly as shown in
Figure 3-5.
