9. Adjustment of horizontal zero (O) balance with stylus pressure and anti-skating :
a. Remove the stylus protector. Do not touch the stylus tip during the adjustment.
b. Set the cueing lever to the lower position so it does not effect tone arm height.
c. Release the arm clamp and lift the tonearm from the armrest so it moves freely.
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 "O" of the ring into alignment with the
center line on the tonearm rear shaft.
g. Rotate the counterweight with scale ring clockwise to the correct stylus
pressure following the manufacturer's recommendation.
h. Set the anti-skating control knob to the same value as the stylus pressure
unless your manufacturer specifies otherwise

continual removal. If you need to remove the lid press both release tabs

OPERATING INSTRUCTIONS
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 turntable mat. When playing a 45rpm record with a large center hole, place the 45-rpm
adapter on the center spindle.
3. Set the rotation speed (33/45) to match the record.
4. Remove the stylus protector and 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. To suspend play, lift tone arm with cueing lever.
10. When play is finished, raise the cueing lever, move the tonearm to the armrest, and secure the tonearm with the
arm clamp.
11. Press the Start/Stop button to stop the platter rotating, push the power button to turn off the power.
PITCH ADJUSTMENT
The pitch control is variable in a range of +/-10%. During play, observe the strobe dots. If the strobe dots appear
to the right, the pitch is slower than the rated speed. If flow to the left, the pitch is faster than the rated speed If the
strobe dots appear stationary, which means the platter is in normal turntable speed, move the pitch control slider up
or down to adjust the speed.
PLACEMENT
·
·
·
Do not place the unit in a location where it will be exposed to direct sun light or near a heating appliance.
Do not place the unit in a location where there is high humidity or a lot of dust.
Cartridge may pick up slight sound pressure or vibrations of the speakers coming along the floor or through
the air resulting in howling. Find a location, which is very stable and free of vibration.
·
The legs have functions for adjusting the height of the unit itself. Adjust the legs to stabilize the main body
horizontally.
MAINTENANCE
·
·
·
Clean the stylus periodically with a soft brush to prevent the accumulation of dust.
When the sound becomes distorted or noisy, check the stylus. If worn out, replace it with a new one.
From time to time, the dust cover and turntable cabinet should be wiped with a soft, dry cloth. Any volatile
materials as alcohol, thinner, benzene, etc., may remove the paint or damage the luster, should not be used.
