QUICK-START  
Turntable Quick-Start:  
1. Changing Platter Speed  
Use the RPM selectors (10 & 11) to change the platter speeds. The 33-rpm (10) and 45-rpm (11) speed  
selectors change the platter rotation respectively.  
2. Starting and Stopping the Platter  
Use the START/STOP BUTTON (6) to switch back and forth between platter rotation and pause  
modes.  
3. Pitch Control  
1. The pitch adjustment is a fine adjustment to the platter's RPMs.  
2. The pitch adjustment is variable and may be adjusted between -10% and +10% of the platter  
selected speed.  
3. The pitch is changed by sliding the Pitch Slider (12) in an up and down motion.  
4. The STROBE INDICATORS (2) on the rim of the PLATTER (20) can be used to visual approxi-  
mate the platter pitch. These indicators are lit by the STROBE INDICATOR PILOT LAMP (4) as  
they pass by the POWER SWITCH (5). At different pitch levels each row of STROBE INDICATORS  
(2) may appear stand still.  
Note: The use of heavy fluorescent lighting directly above the turntable will defeat the STROBE  
LAMP PILOT LAMP (4) affect indicator accuracy.  
Product Service:  
1. Clean the stylus periodically with a soft brush to prevent the accumulation of dust.  
2. When sound becomes distorted or noisy, check the stylus. If the stylus is worn out, replace  
it with a new one.  
3. From time to time, the dust cover and turntable cabinet should be wiped down with a soft,  
dry cloth.  
4. Volatile materials should not be used, such as: alcohol, thinner, benzine etc. They may remove  
the paint or damage the luster.

heating appliance.  
2. Do not place the unit in a location where there is high humidity or a lot of dust.  
3. Cartridge may pick up slight sound pressure or vibrations of near by speakers. For best results,  
do not install this unit too close to speakers.  
4. Install this unit on a horizontal surface that is stable and vibration free.  
5. The rubber feet have been specially designed to isolate the unit from excess vibration. The feet  
may also be used to stabilize the main body horizontally. Adjust the height of the unit by turning the  
feet in a clockwise or counter-clockwise direction.  
Tonearm Balance and Stylus Pressure:  
Adjustment of horizontal zero balance and stylus pressure:  
1. Remove the stylus protective cover, if so equipped. Never touch the stylus tip during the adjust  
ment.  
2. Lower the TONEARM LEVER (13).  
3. Release the tonearm clamp and release the tonearm from the arm rest.

horizontally (floats freely).  
6. Return the TONEARM (9) to the arm rest and lock it in place.  
7. Hold the COUNTERWEIGHT (16) 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.  
8. Rotate the COUNTERWEIGHT (16) clockwise until the scale value corresponding to the recom-  
mended stylus pressure.  
Note: The recommended stylus pressure of the optional cartridge that may have been included with  
your unit is 2 grams. For all other cartridge systems please refer to the manufactures specification  
included with the cartridge.  
Anti-Skate:  
The anti-skate adjustment prevents the TONEARM ASSEMBLY (9) from skipping across the record  
from the centrifugal force that is caused spinning rotation of the PLATTER (20). The ANTI-SKATING  
(15) control knob should be set to the same value as the stylus pressure. For example if your  
COUNTERWEIGHT (16) is set to 2.5 grams the ANTI-SKATE (15) value should also be set to 2.5.
