1.01 This practice provides the description,
installation, and maintenance information for the
QSKlO0 and 2100 Type Contempra telephone sets.
1.02 This practice is reissued to update information
on the Contempra sets. Because of the extensive
additions, the location of these additions isnot noted
throughout this practice. Remove from the file and
destroy all copies of CTSP480-101-401, Issue 1,
1969.
2. DESCRIPTION
2.01 The Contempra is a two-piece telephone set
(Figure 1)consisting of base and handset, and is a
combined desk-wall-type telephone. Wheri used as a
desk-type telephone, it rests on the feet provided in
the base of the set. When used as a wall-type set, it is
mounted by using the mounting holes in the
baseplate.
2.02 When the Contempra telephone set is used as
a desk set, and the handset is in place, it rests in the
recess provided in the base of the set.. When the
Conlempra telephone is used as a wall set and the
handset is in place, the lower edge of that portion of
the handset that houses the receiver unit engages a
projection provided as part of the handset recess.
2.03 The transmission circuit isthe same as for o 500
type telephone set.
2.04 The QSK100 type telephone sets are equipped
with a NE-l0QA rotary dial (exceptQSKlOOCwhich
has no dial), while the QSK2100 type telephone sets
are equipped with a QDC1A Digitone dial.
2.05 The QSKl00A and 2100A telephone sets are
single-line telephone sets equipped with rotary and
Digitone dials respectively (Figures 1 and 2).
2.06 The QSKlO0B and 2100B are the rotary and
Digitone dial versions of the "Message Waiting"
telephone sets (Figure 3).
2.07 The QSKlOOCis the "manual" version of the
QSKlOOAand no dial is required (Figure 4).
2.08 The QSK191A and 219A telephone sets are
similar lo the QSKlOOA and 2100A single-line sets
except that they are not equipped with a ringer;
instead, they have a mounting bracket mounted in
place of the ringer, which may be used to mount a
frequency selective type ringer.

talking circuit of the telephone set to either of the two
lines. The switch immediately behind the two-line
slide switch and nearest to the ringer volume control
isa "press-to-operate" switch which may be used as a
grounding or signaling switch. The ringer is factory
wired across Line 1.
3.05 The Contempro telephone sets contain a
printed circuit type network of the QNB18 type,
which is equipped with quick connect type terminals.
Connections are made by pushing the spade tips into
spring clips on either side of the terminal. {Each
terminal holds two spade tips.) To avoid damage to
the leads, use long-,iose pliers to grasp the spade tip
and use a slight sideways rocking motion while
inserting or removing a spade tip. Use caution to
ensure that the shank of the clip is not bent.
3.06 A recall button is located on the handset which
can be used to disconnect for redialing, thus
eliminating the need to operate the switchhook on
each call. However, as the ringer is disconnected by
the switchhook, incoming c_allswill not be received
unless the receiver is on-hOok (sets manufactured
before January, 1970). Forsetsmanufactured after
January, 1970, the ringer is not disconnectedby
switchhook when the receiver is off-hook.
3.07 To adjust the ringer volume, a wheel that
protrudes through the baseplate at the side of the
set has been provided. (See Figure 9.) Moving a
screw will allow this wheel to completely silence the

ringer. However, ringer cut-off must not be provided
unless authorized.
4. INSTALLATION
4.01 Disassembly:
a. To remove the molded housing from the
base:
(1) Remove card retainer (or window)
located near the front of the housing.
To
remove card retainer, insert the tip of the
NS167050 List 3 releaser tool into the small
slotted hole at the edge of transparent
window. Ensure that the tip does not enter the
hole by more than one-eighth of an inchas an
underlying screw may hinder the lateral
movement of the tool. Apply a slight pressure
to the handle of the tool. (See Figure 10.)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.
(2) Remove the number card, if present.
(3) Loosen the exposed captive screw
sufficiently so that the front of the housing
may be lifted free of the base.
(4) Continued lifting of the cover enables the
housing latches to disengage and free the
cover.
b.
To open the handset:
(1) Remove the card retainer and the
number card located above the dial.
(2) Remove the handset grommet by holding
the handset with the back or smooth section in
the palm of the hand. Insert about 1/16-inch
of the tip of the NS16750 List3 releaser tool
into the small slot adjacent to the grommet.
(See Figure 11.) Press the handle of the tool
towards the grommet and push the shank into
the slot as far as it will go. Push the handle of
the releaser tool away from the grommet to
release the returning spring and gently ease
the grommet out of the handset shell.
(3) Once the grommet has been withdrawn,
two screws are exposed. Loosen these two
screws by about 3/ 16-inch only, as it is not
desirable or necessary to remove the_m.
(4) Free (do not remove) the captive screws
in the cord retainer well. Loosen sufficiently to
separate the handset sections at the receiver
end; then slide the smooth or back half of the
handset housing towards the cord grommet to
release this section from the slotted screw
holes at the grommet.
c. Installation of base mounting cord (NE-
D3Q5A):
(1) Enter the spade tipped leads at the
grommeted end of the line cord through the
square hole in the edge of the base.
(2) Push the grommet through the opening
so that the narrow section aligns with the
square projections directly in front of the
grommet entry.
(3) Push the grommet down firmlyto engage
between projections.
(4) Press the jacketed portion of the cord into
the channel beside the NE-DIQA ringer and
between the projections located about
midpoint on the base. Dress the leads under
the existing wiring; loop them around the
right side of the housing screw stud and
connect to the terminal block in accordance
with Table 8 or D.

4.02 Wall Mounted (Figure 12):
a. Remove line cord. The center key opening in
the base is normally used for the entry of the
station wiring. The slots at the hookswitch end of
the-set and the one just below the ringer are used
for normal wall mounting. For mounting on an
outlet box, the key at the center of the set and the
one just below the ringer ore used. Additional
space may be opened for the entrance of wire
from the outlet box, when necessary,
by
placing
the set on a flat surface, placing a screwdriver in
the detent adjacent to the center key and giving
the screwdriver a sharp knock downward. This
action will shear out an additional opening
leading into the center key. If a mounting screw
fails to hold, knockouts can be made near the
handset cord or under the switch plunger, as
necessary, for the addition of another screw
without having to move the complete installation.
These knockouts should not be opened
unnecessarily. If it isnecessary to bring the station
wire up the wall from the baseboard, an opening
can be uncovered for wire entry by removing the
handset cord grommet from the base, rotating it
180° and replacing it.
b.
To
provide the ringer cut-off feature (when
authorized), change the position of the lever
associated with the ringer volume control wheel.
With housing of the base off, remove the screw
that holds the lever in contact with the wheel, shift
the lever to the opposite end ofthe slot, place the
screw in the hole that was under the lever and
tighten.
4.03 Reassembly:
a. Base:
(1) Dress line cord leads and other wiring
away from the housing retaining screw post
on the base of the telephone set.

(2) locate housing at on angle to the base as
shown in Figure 13.
(3) Press rear of ho\Jsing down and toward
the bock of the base to engage the housing
latches with the notches in the base.
(4) Push front of housing down, ensuring that
latches remain in notches, so that the
retaining screw enters the tapped post inthe
base.
(5) Carefully tighten the screw snugly,
without undue force.
(6) Insert a station cord number and the
retainer window in the well in the base.
b. Handset:
(I) Align the jacketed portion of the handset
cord which projects beyond the grommet and
into the handset, so that itwill fit the channel
in the transmitter cup assembly.
(2) Dress receiver leads through clip or dial
cover wire retainer of rotary dials.
(3) Slide the two handset sections together so
that the two slots at the grommet end slide
under the heads of the screws in the
.apparatus section.
(4) Carefully align sections so that the two
screws in the number plate slot will engage
the topped post holes in the other section.
(5) Tighten screws; two in the grommet
cutout and two in the number plate well.
Tighten the screws snugly without undue
force.
(6) Slide the grommet into the square hole in
