Adjusting tone arm and pick-up cartridge
Remove stylus guard carefully. Turn the anti-skating
knob (2) counter-clockwise until it stops (Fig. 6).
Screw the tonearm counter weight (3) onto the rear
tonearm tube (Fig. 5).
Unlock the tone arm (4) a bit towards the centre of
the platter. Bring the lift-lever (5) into position
while holding back the tone arm (Fig. 6).
By turning the counter weight (3) the tone arm can
be precisely balanced in order to make it hover
freely above the platter. Move the tone arm back to
its rest.
You can now adjust the tracking force (1) and
the anti-skating force (2).
