CHANGING THE SPEED
As long as the pitch control is in center “detent” click position, the turntable is operated at selected speed.
The speed can be increased or decreased by 10% by the pitch control.
An incorrect adjustment done on purpose can also be used to have the turntable rotate extremely slow or fast.
The strobe dots at the edge of the turntable are used for speed monitoring.
MAINTENANCE
Clean the stylus periodically with a soft brush to prevent the accumulation of dust.
When sound becomes distorted or noisy, check the stylus. If the stylus is worn out, replace it with a new one.
From time to time, the dust cover and turntable cabinet should be wiped down with a soft, dry cloth.
Volatile materials should not be used, such as: alcohol, thinner, benzine etc. They may remove the paint or damage the
luster.
