ADJUSTMENTS BEFORE USE
Perform the tracking force and anti-skating adjust-
ments before operating your turntable.
TRACKING FORCE ADJUSTMENT (See Figs.
4,5,6,7)
The tracking force adjustment should be done be-
fore playing. The tracking force must be adjusted
to the recommended value as shown on the in-
struction sheet of the cartridge.
1. Undo the rest hook, and set the anti-skating
knob ‘0’ to the anti-skating index line. (See
Fig. 4)
2. Rotate the weight sleeve and set it so that the
tracking force index line can be seen for about
10 mm.
3. Adjust the horizontal balance as follows:
(a) First, proceed with a coarse adjustment. Move
the balance weight along and set so that the
tonearm is almost horizontal. (lf the tonearm
is not horizontal even when the balance weight
is moved right along, rotate the weight sleeve.)
(b)Now proceed with the fine adjustment. Rotate
the weight sleeve so that the tonearm comes to
rest horizontally. (See Fig. 5)
