to the recommended value as shown on the in-
struction sheet of the cartridge.

knob '0' to the anti-skating index line. (See

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)
