9.ADJUSTMENTS
9.1STYLUS LOWERING POSITION ADJUST.
MENT
1. hess the OPEN/CLOSE key, pull the slidebase
out forwards, place a 30cm record on the tun-
table platter, and set the correct Revolution by
the speedselector.
2. Pressthe START key to start play. Check the
direction and degree of stylus displacement at
this time.
(Estimate the approximate distance in mm that
the stylus lands from the lead-in gtoove).
3. Depending on the direction and degree of dis-
placement, adjust the adjustment screw indicat-
edin Fig. 9.1with a small screwdriver.
* TUm the screwclockwise (asseen
fromabove)
if the stylus lowers outside the lead-in gfoove.
* T\rrn the screw counter clockwise (as seen
from above) if the stylus lowers inside the
lead-in gloove.
* One half-tum of the screw corresponds to a
shift of about 9mm in the lowering position.
4. When using the PLS-2001Stest record, adjust
the screw to obtain a count in the 305 to 317
range for lowering onto a 30cm record. And if
the GGF-021 test record is used, adjust to a
count between 6 and 30 for a 30cm record.
Nofes.'
* Remornl of the bonnet simplifbs adjustment oper-
ations.
In thb case,djuetmentE canbe
performed from
the top of the eecutcleon couer.
* Do not hcline the turntable ouer too far, not apply
excesiue prcesuve
to the adjustment acrewduring the
ad,jtstment operatio
n.
9.2 END DETECTOR ADJUSTMENT
1. Remove the bonnet, svyitchthe power on, press
the OPEN/CLOSE key, and pull the slide base
out forwards.
2. Press the MANUAL key to put the turntable
into manud play mode, and then switch the
power off.
3. Disconnect the CN2 and CN4 connectors on the
common circuit board, and connect a DC volt-
meter to pin l ard pin 3 (GND) of TP1.
4. Switch the power back on, move the stylus to a
position 47.5mm from the center spindle, and
readthe voltage.
5. Then move the stylus to a position 57.5mm
away from the center spindle and read the
meter again. The difference between the two
voltage readings should be 5.6V t 0.2V. Adjust
VRl to obtain this difference.

6. The voltage difference is decreasedby ttuning
VR1 clockwise, and increasedbyturning counter
clockwise(see
Fig. 9.4).
Note:
Shade the sensor section from erternal light during this
adjustment.
9.3 PHONO MOTOR SPEED ADJUSTMENT
1. Remove the bonnet and switch the power on.
Place a stroboscope on the turntable platter,
and press the MANUAL key to put the ttun-
table into manual play mode.
2. Switch the speed selector to 33-1/3rpm, and
adjust VR2 to obtain the "stationaxy" strobo
effect.
3. Then switch the speed selector to 45rpm, and
adjwt VR3 to again obtain the ,,stationary,'
strobo effect.
4. Turntable speed is increased by turning the
adjustment controls (VR2 and VR3) clockwise,
and decreased
by turning counter clockwise.
9.4 STYLUS HEIGHT ADJUSTMENT
1. Remove the bonnet, switch the power on, press
the OPEN/CLOSE key, and pull the slidebase
out forwards.
2.Place a record on the turntable platter, and press
the MANUAL key to movethe tonearm forwards.
3. While holding the tonearm in the left hand,
adjust the adjustment screw with a wrench
(1.5mm) passd through the adjustment hole as
shown in Fig. 9.6.
4. Adjust the stylus to a height 5 to gmm above
the reeord.

DE L'AIGUILLE.
1.Presserla ci6 OPEN/COLSE, tirer la basecoulis-
santeversI'avant, mettre un disque de 30cm. sur
le plateau et positionner le s6lecteur de vitesse
sur le nombre Rdvolution correct.
2. Presser la ci6 START pour faire marcher Ie
tourne-disques. V6rifier la direction et le degr6
de d6placement de I'aiguille d ce moment.
(Estimer la distanceen mm. del'6loignement de
l'aiguille du premier sillon.)
3. Selon la direction et le degr6 de d6placement,
r6gler la vis de r6glage avec un petit tournevis
commeil estindiqu6 Fig. 9.1.
x Toumer la vis vers la droite (en regardant
du dessus) si I'aiguille s'abaissei I'int6rieur
du premiersillon.
* Tourner la vis vers la gauche (en regardant
du dessus)
si l'aiguille s'abaissei I'ext6rieur
du premier sillon.
* Un demi tour de la vis correspond i un d6-
placement de la position d'abaissement de
9mm environ.
4. Lorsque le disque d'essai

r6gler la vis pour obtenir une lecture entre 305
et 3I7 pour I'abaissement

Pour le disque d'essai GGF-021, r6gler pour
obtenir une lecture entre 3 et 30 pour un disque

Remarques:
* Enleuer le capot facilite l'opdration de riglage. Dans
ce coa,Ie riglage s'opire par le haut, sous le couuercle
