Desktop Installation
Note: You may use the 6400 Series telephones

the desktop stand.
In this case it is suggested that you place small round feet (included in
a plastic bag in the box in which the telephone was packed) on each
corner of the bottom of the telephone housing.
1. Turn the telephone face down on a flat surface.
2. Snap one end of the line cord (D2R or D8W) into the “LINE” jack on the
back of the telephone (shown as 3 in Figure 5).
3. Thread the line cord through the routing channel leading to the top of
the desktop stand (2 in Figure 5). Make sure that the cord is placed
securely under the square tabs in the routing channel.
