OPERATION PRECAUTIONS
1. Always clean the stylus both before and after
playing a record with a soft brush, and try to make
it a rule to clean the record with a soft brush and
try to make it a rule to clean the records with a
good quality cleaner.
• Cartridge may pick up slight sound pressure or
vibrations of the speakers coming along the
floow or though the air resulting in feedback or
howling sound. Find a location which is very
stable and vibration free.
• The legs have functions for adjusting the height
of the unit itself. Adjust the legs to stabilize the
main body horizontally..
3. The model may not be able to perform at its best in
an extremely cold envirnment. The optimum
ambient temperature range is 0oC to 35oC.
4. Place only one record at a time on the platter. If
two or more records are sacked on the platter, the
stylus will not make proper contact with the
grooves, and this will impair the quality of
reproduction.
2. Be careful not to make the turntable vibrate while
a record is playing, since this can result in
damage to the stylus and record.
3. When clanging over the headshell, clamp the
tonearm to the arm rest so that the tonearm shaft
is not strained in any way.
5. Volatile materials should not be used, such as :
alcohol, thinner, benzone etc. They may remove
the painter or damage the lustre, please avoid.

(d) Rotate the counterweight until the tonearm is
approximately balanced horizontally (floats freely).
(e) Refasten the tonearm with the arm clamp.
(f) Hold the counterweight stationary with one hand
and rotate only the stylus-pressure ring to bring
the number "0" of the ring into alignment with the
center line on the tonearm rear shaft.
6. Insert the headshell into the front end of the
tonearm, then turn the lock nut clockwise with the
headshell firmly held horizontally.
7. Slide counterweight onto tonearm.
Twist it lightly and it will screw onto the rear shaft
of the tonearm.
8. Adjustment of horizontal zero (0) balance and
stylus pressure:
(a) Remove the stylus protector, do not touch the
stylus tip during the adjustment.
(b) Set the cueing lever to the lower position.
(c) Release the arm clamp and lift the tonearm from
the arm rest to free it.
(g) Rotate the counterweight clockwise until the scale
shows the value corresponding to the pressure of
the used stylus. The stylus pressure of the installed
pick-up system is 2 g. If you use a separate pick-up
system, please follow the manufacturer’s
i n s t r u c t i o n s .
9. Set the anti-skating control knob to the same value
as the stylus pressure.
10. Install the dust cover to the main unit.

O P E R A T I O N STYLUS REPLACEMENT
1. Push the power button to turn on the power, the
speed indicator and the strobe-illuminator will light up.
2. Place a record on the slip mat, when playing a
45rpm record with a large center hole, place the
45-rpm adaptor on the center spindle.
3. Set the speed to match the record.
4. Remove the stylus protector, release the arm clamp.
5. Set the cueing lever to the up position.
6. Press the Start/Stop button, the turntable platter
will start to rotate.
7. Move the tonearm over the desired groove.
8. Set the cueing lever to the down position, the
tonearm will descend slowly onto the record and
play begins.
9. When play is finished, raise the cueing lever, move
the tonearm to the arm rest, secure the tonearm
with the arm clamp.
10. Press the Start/Stop button to stop the platter
rotating, push the power button to turn off the power.
Suspend play
Set the cueing lever to "UP"position during play, the
stylus tip of the cartridge will be lifted from the record.
Target light
This unit is provided with a target light for illumi- nating
the stylus tip during play.
Push the target light button, the target light will be
raised into position for illuminating the stylus tip.
When not in use, keep the target light lowered
through depression.
CHANGING THE SPEED
As long as the pitch control (13) is in center click
position,the turntable is operated witch quartz- controlled
rated speed.The green LED (12) will then be lit.
The speed can be increased or decreased by 10% via
the pitch control (13). The red LED (12) will then be lit. If
the change of speed does not correspond to the pitch
control change, it is possible to correct this with the trim
control (15).
An incorrect adjustment done on purpose can also be
used to have the turntable rotate extremely slow or fast.
The strobe dots (4) at the edge of the turntable issued
for speed monitoring.
The life expectancy of the stylus tip is 500 hours. For
the sake of maximum sound quality reproduction, we
recommend replacement within the minimum time limit.
1. The stylus tip is replaced by grasping the stylus
holder and pulling it away from the body of the
cartridge.
2. The new stylus tip s then inserted by pushing it into
the receptacle.
CARTRIDGE REPLACEMENT
Remove the headshell from thd tonearm, and the
screws that hold the cartridge. Pull out the four lead
wires from the cartridge itself. To protect the lead
wires at this point, remove the terminal pins with
pliers or the tip of the screwdriver.
The terminals on the accessory headshell are aligned
according to the arrangement below. Check the
location and polarity of each of the cartridge’s
terminal pins and then connect the lead wires, taking
care not to get the polarities mixed up.
