Note:

- Set the Stylus pressure to the maximum recommended
value for your cartridge in cases where the record has an
extremely high recording level, or where the unit is
operated in a room at low temperature, or in places in
which the unit is subjected to vibrations.

Adjustment of anti-skating control

Set the anti»skating control knob to the same value as the

stylus pressure. (See Fig.13,)
Note:

- When a cartridge with integral dust brush is used, follow
the cartridge manufacturer's recommendation for adjust
ing both stylus pressure and anti-skating force.

Adjustment of arm-lift height

(See Fig. 14)

. The arm»lift height distance between the stylus tip and
record surface when cueing knob is at v" has been ad-
justed at the factory before shipping to a_pproximately 5
to 10 mm.

a For using different cartridges available on the market or
when further adjustments are particularly necessary,
make adjustment as follows:

4. Turn the adjustment screw clockwise or counterclock-
wise, while pushing the arm lift down. (See Fig. 14.)

Clockwise rotation

- distance between the record and stylus tip is re-
duced.

Counterclockwise rotation

-- distance between the record and stylus tip is in-
creased.

Note:

a As the adjusting screw has a hexagonal head, be sure to
make the adjustment while depressing the arm lift, or
the screw will not move freely. Also be sure that the
hexagonal head retracts correctly into the arm lift when
the latter is released.

Speed adjustment (with pitch control knobs)

Strobe dots are set on the rim of the turntable platter
according to the powerline frequency and the speed of the
records. Make adjustment, referring to strobedot indica»
tion.

1. Place a record on the turntable mat.

2. Set the speed select knob to the speed to be adjusted.

3. Adjust the speed while playing a record,

The strobe~i|luminator/pilot lamp will be lit for illumina-
ting the strobe dots.

4. While turning the pitch control knobs either to + side
or "-" side, adjust so that the strobe dots of the turn-
table platter look as if they were stationary. The state
under which the strobe dots seem to be stationary
represents the correct number of revolutions.

"+" direction

This increases the speed of the turntable rotation,and the

strobe dot pattern seems to flow in the same direction as

the rotational direction of the turntable platter.

-" direction

This decreases the speed of the turntable rotation, resulting

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 fluctu-
ation of about 0.2%. 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.

Adjustment for automatic start and return positions
Should the tonearm not function correctly, make adjust-
ments according to the following procedures.

Adjustment for automatic start position

(Remove the rubber cap.)

In cases where the stylus tip descends outside of the record
-Rotate clockwise.

in cases where the stylus tip descends onto halfway of a
recorded piece

-Rotate counterclokwise.
