10. Adjustment of horizontal zero (O) balance with stylus pressure and anti-skating :
(1) Remove the stylus protector, do not touch the stylus tip during the adjustment.
(2) Set the cueing lever to the lower position so it does not effect tone arm height.
(3) Release the arm clamp and lift the tonearm from the arm rest so it moves freely.
(4) Rotate the counterweight until the tonearm is approximately balanced horizontally (floats freely).
(5) Refasten the tonearm with the arm clamp.
(6) Hold the counterweight stationary with one hand and rotate only
the stylus-pressure ring to bring the number "O" of the ring into
alignment with the center line on the tonearm rear shaft.
(7) Rotate the counterweight with scale ring clockwise to the
correct stylus pressure following the manufacture's
recommendation.
(8) Set the anti-skating control knob to the same value as the stylus pressure unless your
manufacturer specifies otherwise
