bar
219
are positioned in
the area of the spring
pin F of segment
207.
When moving slowly the
tonearm with tonearm cue control in
•
position the spring pin F is
arrested in the recesses of slide
bar 217 thus
designing the set-down point of
stylus for 30 cm
and
17 cm records.
To
enable set-down in the catching range
of the arresting point
of the appropriate setdown
position, the tonearm
set-down me-
chanism can be disengaged with the knob
62 in "—" position.

Balance tonearm 48
exactly. Bring knob 62 into
"V" posi-
tion. Let tonearm catch

Short
Circuiter
To
prevent disturbing noises
during automatic operation
of the
tonearm
the
unit is fitted with a short
circuiter.
Control of the
switch springs for both channels is effected by the
camwheel.
With the unit in neutral state the short circuit of the pick -up
leads is eliminated.
Adjustment
In
zero position
of the cam there should be a
clearance of ap-
proximately 0.5 mm between the
contacts of the short circuiter.
This clearance should be adjusted by bending the
short circuit
contact. The contacts should be
sprayed with a suitable cleaning
agent.
