m ADJUSTMENTS
Speed adjustment (with pitch control knobs)
(See Fig. 2)
Strobe dots are set on the rim of the turntable platter
of revolutions of the records.
Make adjustment, referr-
ing to strobe-dot indication.
1, Place a record on the turntable mat.
2. Set the speed selector to the speed to be adjusted.
3. Adjust the speed while playing a record
The
strobe-illuminator/pilot
lamp
will be lit for
illuminating the strobe dots.

Strobe dots
The strobe dots for 60 Hz,
33'/+rpm
seem tobe
stationary.

"+"" direction
This increases the speed of the turntable rotation, and
the strobe dot pattern seems to flow in the same direc-
tion as the rotational direction of the turntable platter.
"—" direction
This decrease the speed of the turntable rotation, result-
ing in a state opposite to that in the '+' direction.
Note:
Strobe dot pattern
The
strobe-illuminator/pilot
lamp of this unit employs
the commercially available power source. The frequency
of such
power
source, when actually measured, has a
fluctuation of about 2%.
As such a fluctuation of the
power source affects the strobe illuminator, the strobe
dot pattern also seems to fluctuate to a certain extent.
But the unit is not affected by these fluctuations of the
power source, since a DC motor is employed.
In other
words, rotation of the platter will be constant, and slight
shifts in the movement of the dots simply reflect normal
drift in the power-source frequency.
(Remove the turntable mat.)
In cases where the tonearm tends to return before play-
ing has finished.
—Rotate clockwise.
—Rotate counterclockwise.
