Tonearm height adjustment
@ Place a record on the platter and lower the cartridge onto a
record.
@ Release the Tonearm Height Adj. Knob toward you and move
it in the required direction so that the tonearm becomes parallel
to the turntable.
eCalibration is in mm.
© When the adjustment is complate, lock the Knob.
@ Lift up the Tonearm from the record surface by setting the
Cueing Lever to the [ y ] position. Be sure that the distance be-
tween the stylus tip and the record is 5 to 10 mm. If not, adjust
the height of the Tonearm Platform by loosing its screw as
illustrated. Adjust so that the Tonearm Platform do not swerve
from a concentric circle.
Arm Rest height adjustment
When the Tonearm height is changed, the Arm Rest height
adjustment is also required.
@ Be sure that the Tonearm Platform is up.
@ Pull up the upper portion of the Arm Rest and turn it clock-
wise. Place the Tonearm on the Arm Rest.
© Loosen the screw so that no clearance is left between the
Tonearm and the Arm Rest. Retighten the screw.

*1 Longitudinal balance adjustment
While playing the record, the weight of the tonearm is supported by the arm
pivot and only tracking force is applied to the stylus tip. To accomplish this, the
tonearm must first be balanced horizontally, with the tracking force indicator set
at "0".
*2 Tracking force
After the longitudinal balance adjustment, apply the recommended tracking force
weight so that the stylus tip will trace the music groove accurately.
*3 Overhang
In record playing, because of the pivoted design of the tonearm, the stylus tip
can be perfectly tangent to the music groove at only one point of the record.
At all other portions of the record, there is a slight deviation of the stylus from
tangency. This is called the tracking error, and introduces minute errors in the
amplitude and timing of the reproduced signal as compared to the original, and
other forms of distortion which may be introduced depending on the cartridge
and stylus design.
Tracking error is minimized by the selection of an optimum "off-set" angle and
"overhang" distance. Overhang is the distance between the stylus tip and the
center spindle. This overhang adjustment is made at the time of installing a
particular cartridge, while the off-set angle is fixed by the manufacturer of the
tonearm.
*4 Anti-skating compensation
While the record is being played, the frictional force between the record groove
and the stylus produces a force that tends to drive the tonearm toward the center
of the record. The anti-skating compensation cancels the above mentioned
force, and is applied in accordance with the tracking force.
Incorrect anti-skating compensation results in sound distortion and uneven wear
on both the stylus and the record.
