receptacle.

Insert the other end of the long ribbon cable into receptacle D as
shown in Figure 4-2. Slide the ribbon cable underneath the
restraining tabs H so that it is not twisted and so that the
ribbon cable avoids the screw mount. This placement ensures
that the cable will not be pinched or squeezed by the screw once
the extended base is attached.
If you are adding a second M522 (2) to the telephone set, use the
short ribbon cable (172 mm) to connect it to the M522 already in
place. On the M522 (1) already connected to the telephone set,
insert one end of the short ribbon cable into receptacle E. On the
second M522 (2), insert the other end of the ribbon cable into
receptacle F. Make sure the ribbon cable is not pinched or
twisted.
