(3) Adjusting the Inside Force Canceler
1) To install Inside Force Canceler, secure the
tonearm to the arm rest.
2) Insert the Inside Force Canceler roller stand,
an accessory, into the post as shown in Fig. 8.
3) Hang the string, connected to the bi as ­
weight, over a groove on the bias lever (this
hangi ng position will be adjusted later) and
place the string over the roller.
4} The stri ng position on the bias lever is decided
by the stylus tracking force. The first groove
corresponds to 19 and other grooves provide
O.5g step increases, the end groove thus
corresponding to 2.5g. Select the groove to
meet your stylus force. For example, hang the
string over the third groove (from the end) for
1.5g cartridge stylus force. (See Fig. 9).

(4) Adjusting tonearm height
1} If your cartridge has a stylus guard, remove it:
if it is permanently hinged in position, lift it
up.
2} Place a disc on the turntable platter. Set the
POWER/SPEED switch either to ON/33 or
ON/45 position, then lower the stylus tip on
to the disc surface. If the tonearm is found
failing to parallel the disc surface at this time,
puts the tonearm back to the armrest once.
And, while keeping the tonearm in the arm
rest, loosen the arm-base lock nut, and gently
move the tonearm proper (upward or down­
ward) so that it becomes parallel with the disc
surface. After this adjustment, place the stylus
tip once again on to the disc surface and see
if parallelism in question has been attained.
Should it be still found otherwise, repeat the
above same adjustment to finally bring the
tonearm completely parallel with the disc
surface.
Make sure to tighten the lock nut firmly to
the arm-base when adjustment is completed.
NOTE: During adjustment of tonearm height,
the turntable keeps turning. Therefore, be
careful so as not to give damage to the stylus
tip or a disc.

3} Once the tonearm height adjustment has been
completed, secure the tonearm to the armrest.
Adjusting stylus height
In case the position of the stylus tip comes to
differ due to cartridge replacement, adjust the
stylus height as shown in Fig. 11 by means of the
adjusting screw and accessory screwdriver.
1} Turn MOTOR/CUE switch to CUT position.
2) Bring the tonearm over the disc surface.
3) To raise the stylus, turn the screw clockwise.
4) To lower the stylus, turn the screw counter ­
clockwise.
5) Adjust stylus height between 4mm to 10mm
with this screw.
