M@ Adjustment of muting timing (height of arm lift)
(See Figs. 27 and 28.)
This unit is fitted with a muting feature which is used to
cut off irritating noise caused at the moment the stylus is
brought down on or lifted up from the disc surface.
Muting timing can be adjusted by the height of the arm lift, a
clearance between the stylus tip and the disc surface while the
top of the tonearm is at the “up” position (¥), by depressing
the cueing switch button. The height of the arm lift was adjust-
ed to arange of 8~13 mm before shipment from the factory.
(See Fig. 27.) Perform the adjustment in the following manner
when adjustment is needed for the cartridge being used.
e To begin with, protect the tip of the stylus with the stylus
cover.
e Turn off the power switch () so that the turntable should
not move.
e The top of the adjust screw is hexagonal.
While holding the arm lift down, turn the adjust screw.
Remember to depress the arm lift downwards in turning the
adjust screw. (See Fig. 28.)
If recorded sound cannot be reproduced at once after the
stylus was lowered on to the disc surface,
try to adjust the timing by turning the adjust screw counter-
clockwise, and thus increasing the distance between the sty-
lus tip and the disc surface.
In case irritating noise is generated when the stylus is lowered
on to the disc surface,
decrease the distance by turning the adjust screw clockwise.
Note:
As the adjusting screw has a hexagonal head, be sure to
make the adjustment while depressing the arm lift, or the
screw will not move freely.
Also be sure that the hexagonal head retracts correctly
into the arm lift when the latter is released.
Adjustment for automatic start position
(See Fig. 29.)
Auto-start position (where the stylus tip lowers onto the re-
cord surface during automatic play mode) should be adjusted
with arecord on the turntable platter. If the tip of the stylus
does not land at a proper location on the record, it should be
adjusted in the following manner. Be sure to use a 30 cm disc
for adjusting the auto-start position.
1. Clamp the tonearm to the arm rest.
2. Take the rubber cap off the auto-start position adjust-
ment screw. Then, turn the adjustment screw clockwise
or counterclockwise with a screwdriver.
3. If the stylus tip descends onto the sound grooves, the
adjustment screw must be turned clockwise.
4. If the stylus tip descends outside the record, the adjust-
ment screw must be turned counterclockwise.
5. The auto-start position must be adjusted so that the tip of
the stylus descends 1 to 2 mm from the lead-in groove.

headshells
are
employed,
the
handle
portion
of
the
headshell
may
strike
against
the
inner
upper
surface
of
the
dust
cover
during
automatic
motion
of
the
tone-
arm.
In
such
acase,
we
recommend

off.
Detaching
or
attaching
of
the
headshell
with
the
volume
con-
trol
turned
up
may
cause
damage
to
the
speakers.
Wipe
the
dust
cover
and
turntable
base
with
a
soft,
dry
cloth.
Never
use
any
cleaners
containing

solution.
Do
not
wipe
the
dust
cover
during
play,
or
the
tonearm
may
be
attracted
toward
the
dust
cover
due
to
the
generation
of
static
electricity.
Dust
and
dirt
should
be
carefully
removed
from
stylus
tip
or
records.
Dust
and
dirt
on
the
stylus
tip
or
record
may
not
only
result
in
deterioration
of
tone
