5. Adjustment
Procedures
The following adjustments should be performed only when
replacing a cartridge or a headshell.
Otherwise, no adjustment is required.
If necessary to replace a cartridge, usage of that headshell
exclusive to this unit is recommended.
5-(1) Overhang Adjustment
To obtain optimum overhang, when mounting the cartridge,
first align the cartridge's longitudinal axis with that of the
headshell
and position the cartridge so that the distance
between
the headshell's end face and the stylus tip equals
48mm as shown in Fig. 8-A.
Be sure to tighten the set screw after the adjustment. Errors
within 1mm are negligible from a practical point of view.
5-(2)
Headshell Angle Adjustment
If the headshell
is not horizontal and the stylus tip is not
perpendicular to the record surface, loosen the lock screws
using a small screwdriver and adjust the headshell unit the
stylus tip is set at a right angle as shown in Fig. 8-B. Eye
measurement is sufficient.
Be sure
to retighten the screws after the adjustment
is
completed.
5-(3) Tonearm Lifter Height Adjustment
Adjust the height of tonearm
lifter with the adjustment
screw so that the distance
between
the stylus tip and the
surface of record is about 6mm when the stylus is elevated.
Turn the height adjustment screw clockwise to lower, and
counterclockwise to raise the tonearm lifter level. (See Fig.
9.)
Align the center lines
of the headshell and
i
of the cartridge.
