prevent
disturbing noises
after playing
a
record the unit is
equipped with a muting
switch.
When moving the
tonearm (48) inwards the
con-
tact springs are
actuated by pivoted lauer
(179) and the lifting piece (139)
on the con-
trol arm.
After playing a
record the contacts
are clos-
ed. If the tonearm is
returned to its rest,
the contacts are reopened.
Adjustment
Points:
a) The contact springs (F) of the muting
switch should haue a spring pressure of
40 - 50 p. If necessary, slightly band

position the contact spring
(F) (Fig. 17)
should rest on the radius
of the pivoted lever (179). Adjust by
bending the deflection lever
(178). The
distance between contacts should be 0.3
to
0.5 mm. If necessary, bend contacts
(K).
