® Stylus force adjustment
Adjust the stylus force to the optimum level by
following
the
procedures
explained
below.
Both
the straight-type and S-type arm tubes can be adjust-
ed by the same procedures.
Note:When
using cartridges with
removable
stylus covers, take off the styius cover
before making adjustments.
(1) Set the anti-skating knob to "O". The stylus
force scale rotates three
turns. Rotate
the
stylus force scale in the reverse direction of
the arrow
in Fig. 16 and set it to the last
alignable "0".
(2} Choose the appropriate baiance weight ring
for the weight of the cartridge to be used {refer
to Chart 2} and install it according to the
procedures
explained
previously.
With
the
lifter arm lowered, remove the arm from the
arm rest. Next, slide the balance weight ring
back and forth precisely locating the position
that neutrally balances the arm horizontally.
(if the shell side tips dawn, shift the weight
ring to the rear; if the shell side tips up, shift
the weight ring forward.) (Fig. 15)
P
Note: The arm may move to the left or right
.
* when the horizontal balance is adjusted.
This
is caused
by the high-sensitivity
bearings in the arm base and is not a
malfunction.
(3} Rotate
the stylus force scale knob in the
direction of the arrow in Fig. 16, setting the
reference fine on the arm to the level corre-
sponding to the optimum stylus force of the
cartridge. One full rotation of the stylus force
scale is equal to 1g. Its limit is three rotations
or 3g of stylus force. For example, to set the
stylus force to 2.59, rotate the stylus force
scale twice and one-half tum move to bring
0.5 to the reference line.
® Anti-skating adjustment
Rotate
the
ANTI-SKATING
knob
to
the same
setting es the cartridge stylus force by aligning your
setting with the reference fine. Fig. 17 shows the anti-
skating position when the stylus force is 1.59.
