Turntable operates, but no sound, or sound not loud
enough

1.

If the turntable is connected to an AUX (high-level)
input: The Pre-amp Selector Switch may be set to the
“OFF” position (phono-input level).

2.

The input gain of the amplified speaker or similar
device may be too low.

3.

The stylus assembly may not be fully seated in the 
cartridge body. (See Fig. 9 on page 5.)

Sound is very distorted

1.

Turntable connected to an amplifier’s PHONO input: 
If the pre-amp switch is set to the “ON” position 
(AUX high-level output), a phono input will be 
overloaded.

Turntable moves slightly up and down

1.

Usually this is a normal condition and not a problem.
If this causes the turntable to be unable to trace the
record, please contact your dealer or our service
department. 

Make very certain the surface upon

which the turntable is resting is not picking up
vibrations from the floor or walls, or from direct
speaker sound.

Tips For Better Performance

• 

When opening or closing the turntable cover, handle
it gently, moving it either at the center or equally
from both sides.

Do not touch the stylus tip with your fingers; avoid
bumping the stylus on the turntable mat or a record’s
edge.

Clean the stylus tip frequently, using a soft brush

with a back-to-front motion only.

If you use a stylus cleaning fluid, use it 

very 

sparingly.

Wipe the dust cover and turntable housing gently
with a soft cloth. Use only a small amount of mild
detergent solution to clean the turntable and dust
cover.

Never apply harsh chemicals or solvents to any part
of the turntable system.

Prior to moving the turntable, always unplug it from
the AC outlet and fasten the tone arm on the tone
arm rest with the vinyl twist-tie.

Troubleshooting, continued
