@PITCH CONTROLS
(See Fig. 1)
*Turn either knob clockwise or counterclockwise, as necessary,
to reduce or increase the speed of turntable rotation.
Clockwise rotation
....The speed of the turntabie platter will
decrease.
Rotate
counterclockwise
if the
dots
seem to be "running ahead"; i.e., seem
to be moving clockwise, until they ap-
pear stationary.

Counterclockwise
rotation ............ The speed of the turntable platter will
increase.
Rotate clockwise
if the strobe dots il-
luminated
by strobe
illuminator/pilot
lamp,
seem
to be ''falling back'';
i.e.,
seem
to be
moving
counterclockwise.
When
the dots appear to be stationary,
turntable speed is accurate.
NOTE
Any change in powerline frequency will also cause a change of
the fluctuation rate of the neon lamp or fiuorescent lamp used
for illumination of the strobe dots.
In such case the strobe dots will appear to move very slightly
under normal conditions. The powerline frequency from electric
utiity companies is normally extremely stable without frequency
fluctuation.
Under
certain
abnormal
conditions,
however,
changes
in line frequency
have
been
observed,
averaging
to
about 0.2% when measured over a period of time.
If this happens,
the strobe
dots will move
very slowly.
Such
change in line frequency will in no way affect the quality of the
sound reproduction, as line frequency change does not change
the rate of turntable rotation.
