OPERATION
1. Placethe record to be played on the platter.
2. Set the SPEED select switch to the speed at
which the record is to be played.
3. Set the ARM-ELEVATION lever to the UP
^' position.
4. Remove the stylus cover and releasethe arm
clamp.
5. Hold the headshellby the finger lift and move
the stylus acrossthe record to the track you
want played. The platter will beginto rotate.
6. Observethe appropriate strip of strobe calibra-
tion dots on the platter edge. If the strobe dot
is not stationery, finely adjust the platter speed
with the SPEED ADJ. knob according to
..HOW TO FINELY ADJUST THE PLATTER

The stylus will descend slowly to the record
and play will begin.
8. Adjust the volume and tone controls on the
amplifier to the preferred levels, and then sit

platter stops rotating and the power to the
turntableisturnedoff.
10.Securethe tonearm to the arm rest with the
clamp and attach the stylus cover to protect
thestylus.
OPERATION PRECAUTIONS
. Never obstruct the turntable with the hand
while it is rotating. This may causedamage.
. Do not force the tonearmcloserthan 40mm to
the center shaft or outward from the arm rest. If
this distanceis exceeded,
you may damage
the
internal mechanisms and render automatic
operationineffective.
o Be careful not to make the turntable vibrate
while a record is playing since this can result in
damageto the stylus and record.
. Place
only one record at a time on the platter.
If two or more records are stacked on the
platter,the styluswill not makeproper contact
with thegrooves, andthiswill impairthequality
of reproduction.
o Do not disconnectthe power cord while the
stylus is still in a record grooveasthis may result
in damageto thestylusandrecord.

OPERATION
AND ADJUSTMENT
5.1 START
OF
PERFORMANCE
1. The tonearm is moved from the arm resrro
above
the turntable.
2. LeverA, connected
to the tonearm, unlocks
lever B, and the microswitch is turned ON
(Fig.
1).
3. When
the microswitch
isturnedON, themotor
isstartedand the turntable begins
to rotate.
5.2AUTO.RETURN
DETECTION
1. When
the stylus nears
thecenter
shaft,Iever
A
contactslever
C(Fig.
2).
s
Plate B atop plate A is moved toward gearA
by the movement
of plate
A.
The front endof plate B moves
approximately
0.1mm when the stylus is advanced1mm
toward the center shaft by one revolution of
therecord.
The tooth of gear A has the dimensionaldif-
ference
shownin Fig.4-a.
Plate
B is pushed
back by thisdimensional
dif-
ference
at a stylus movement
of within 1mm
perrevolution
of the record.
When the stylus enters the lead-out groovein
the record at the end of the performance, it
is moved 4mm toward the center shaft by one
revolution
of therecord.
The end of plate B contacts the tooth of gear
A (Fig.
a-b).
Gear A and gear B are engaged,
and gear
B is
turned by rotation of the turntable.

5.4.2 MicroswitchON Timing
1. Adjust at the adjusting
point shown
in Fig.10-b
so that lever A andleverB becomeas
shownin
Fig. 1-0-awhen the tonearm is fastenedto the
arm rest.
2. Adjust the adjusting screw (Fig. 10-c) so that
lever B and the microswitch are positioned as
shown in Fig. 10-c when the tonearm is
fastenedto the arm rest.
3. Since this adjustment will adversely
effect the
auto-return detection position, the auto-
return detection position must bereadjusted.
