(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"
