4.02 DISASSEMBLY
To Remove the Moulded Housing From the Base:
(a) Remove card retainer (or window), loc-
ated near the front of the housing.
To remove card retainer, insert the tip of
the NS16750 List 2 releaser into the small
slotted hole at the edge of the transparent
window. Ensure that the tip does not enter the
hole by more than oJ:lk)-eighth of an inch as an
underlying screw may hinder the lateral move-
ment of the tool. Apply a slight pressure to the
handle of the tool, (See Fig. 6).' The housing
projection provides' a fulcrum. This will bow
the window upward so that its edges may be
grasped with the fingertips of the other hand
to spring it out.

two screws are exposed. Loosen these two
screws by about 3/16" only, as it is not desir-
able or necessary to remove them.

screws in the card retainer well. Loosen
sufficiently to separate the handset sections at

that the narrow section aligns with the
square projections directly in fr9nt of the
grommet entry.
(c) Push the grommet firmly down to engage
between projections.
(d) Press the jacketed portion of the cord into
the channel beside the D1QA ringer and
