4. Arm Rest Height Adjustment
Upon
completion
of Tonearm
and Stylus height adjust-
ments the Arm
rest height must be checked
as shown
in
Fig. 9. If adjustment is necessary follow the steps below.

the arm rest to the lowest position.
2) Depress the B
(STOP) button and return the tonearm
to the arm rest.

button
and lift up the

the center spindle, and by moving the arm rest vertically,
adjust it so that there will be a clearance of 1 ~
2mm
between
the tonearm
and the flat portion of the arm
rest.

NOTES
1) If the stylus height is too low
When
the tonearm
moves
horizontally, the stylus will
tend
to come
in contact
with
the record
surface
or
platter.
2) If the stylus height is too high
Adjusted to a height decidedly higher then the proper
one,
the stylus will float at low portions of a warped
record.
