9. ADJUSTMENTS
Dummy Play Mode Setting
The PL-88F can be set to a dummy play mode
(in "loading out" mode) by the following method.
L. Remove the bonnet, and set to "loading out',
mode.
2. Switch the power off.
3. Disconnect the CN3 connector on the control
ass'y, and short pin (1) to pin (2).
4. Then switch the power on, thereby putting the
turntable into play mode.
Notes:
1. When using this setting (bonnet remoued, attd, loding
out mode) for track selection operations and adjustments, mahe sure that the toneann cartridge section is
protected from extraneous lEht.
2. When cheching add.ress-related, operations (including
operatione during track selection snd. play), do not
manipulate the tonearm by hand. If the tonearm has to
be operated,, use the operation heys,
3. Do not operate the OPEN/CLOSE key.
4. Always make sure that the power is off when connecting or disconnecting the connectors.
Adjustments
Different methods af,e usd to adjust the stylus
lowering position for track 1 and the other tracks
for automatic play operation in the PL-88F. The
lowering position for track 1 is adjusted according
to "Stylus Lowering Position Adjustment", while
the lowering position for other tracks is adjusted
according to "Adjustment of Stylus Lowering
Position between Tracks".
9.1 STYLUS
LOWERING POSITION ADJUST-
M EN T
1. Press the OPEN/CLOSE key, pull the slide base
out forward, place a 30cm record on the turntable platter, and set the correct rpm by the
speed selector.
2. Press the 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 groove ).
3. Depending on the direction and degree of displacement, adjust the adjustment screw indicated
in Flg. 9.1 with a small screwdriver.
* T\:rn the screw clockwise (a.sseen from above) if
the stylus lowers outsile the lead-in groove.
* Turn the screw counter clockwise (as seen from
above) if the stylus lowers iruide the lead-in
gxoove.
* One half turn of the screw corresponds to a shift
of about 9mm in the lowering position.
4. When using the PLS-2001S test 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.
Notes:
* R emoualo f t he b o nnet simplifie s adj ustment operat io ns.
In this ca*, ad.juetmentscan be performed. from the

* Do not incline the turntable ouer too far, nor apply
excessiuepressure to the d,justrnent screw during the
djustment operation.
9.2 ADJUSTMENT OF STYLUS LOWERING
POSITION BETWEEN TRACKS
Use this adjustment method when the stylus
fails to lower correctly into position between tracks
during normal programmed play (when the sensitivity switch is in the NORM position and an
ordinary record is being usd). This position
should also be adjusted after stylus replacements.
1. Pressthe OPEN/CLOSE key, pull the slide base
out forwards, place a 30cm record on the tr:rntable platter, and set the correct rpm by the
speed selector.
2. Press the START key and proceed in progmmmed play mode (excluding the first track from the
program). Estimate the direction and degree of
displacement in the lowering position at this time.
3. Press the OPEN/CLOSE key and pull the slide

o T\rrn the adjustment screw clockwise if the
stylus lowers in the track on the outside of the
prograrnmed track.
o Turn the adjustment screw counter clockwise if
the stylus lowers inside the programmed track.
o One full turn of the screw conesponds to a shift
of 0.2mm in the lowering position.
5. hoceed with programmed play again (excluding
the first track from the program) and check that
the stylus lowers correctly between tracks.
6. When adjusting with the GGF-021 test record,
set the sensitivity switch to the HIGH position,
and then adjust the screw to obtain the lkHz
output signal for three to four seconds when the
stylus is lowered in front of the second track of
the GGF-021record.
7. After completing the adjustment, proceed with
programmed play, and check that the lkHz
output slgnal is obtained for three to four
seconds for tracks after the first track, and that
the lkHz is also obtained for tracks after the
sixth track.
Note:
If the conect lowering position cannat be obtained by
this adjustment methd, or if the stylut lowering operation

9.7 HORIZONTAL DD CANCEL ADJUSTMENT
1. Remove the bonnet, press the START key, and
switch the power off when the tonearm comes
close to the lowering position for 30cm records.
The tonearm remains elevated in this case.
2. Connect an oscillator to P9 and P10 in the

3. Generate a 10Vp-p 45OHz sine wave signal in
the oscillator, and check that a 450H2 sine wave
slgral is displayed in the oscillocope.
4. Adjust VR203 to obtain a 120mVp-p (t10mV)
waveform signal in the oscillocope.
5. Move the tonearm slowly by hand towards the
center of the record. As the tonearm is moved
towards the center from the 30cm lowering
position, the waveform amplitude is gradually
decreased, reaching a minimum at a point a
little before the spindle. Moving the tonearm
any further inwards results in the amplitude
increasing Eatn.
6. Set the tonearm in the position where minimum
amplitude was achieved, and readjust VR203 to

9.9 MOTOR OPERATION POINT ADJUSTMENT
1. Open the slide base as described in "Dummy
Play Mode Setting", and run the motor at 33-1/
3rpm.
2. Connect the buffer amplifier shown in Fig.9.14
to the 3P connector from the motor base plate,
and connect the output to a oscilloscope
(making the lead wire length less than 10cm to
reduce the effects of extraneous electrical noise).
3. With a waveform like that shown in Fig. 9.15 in
the synchroscope, vary the gain to adjust the
peak-to-peak distance in the sawtooth waveform
to five divisions.
4. Then adjust VRl to obtain an a:b ratio of 3:2 in
Frg. 9.15 (taking every precaution to eliminate
unwanted noise).
5. After completing the 33-U3rpm adjustment,
repeat the process for 45rpm. Always adjust the
33-U3rpm speed before the 45rpm speed. And
even if only the 33-U3 rpm speed initially needs
adjustment, also adjust the 45rpm speed after
the 33-1/3rpm adjustment. Adjust VR2 for
45rpm. After completing the 45rpm adjustment,
check the 33-1/3rpm speed.

desplazamiento ajustar el tornillo de ajuste indi
cado en la Figura 9-1 con un pequeflo destorniIlador.
* Girar el tornillo hacia la derecha (visto desde
arriba) si la aguja desciende hacia el exterior
del surco inicial del disco.
* Girar el tornillo hacia la izquierda (visto desde arriba) si la aguja desciende hacia el interior del surco inicial del disco.
x Una media vuelta del tomillo corresponde a un
desplazamiento de aproximadamente de 9mm en
la posici6n de descenso.
4. Cuando se utilice el disco de prueba PLS-2001S,
ajustar el tornillo para obtener un valor comprendido entre 305 a 3L7 de descensosobre un
disco de 30cm. Y si se utiliza el disco de prueba
GGF-021, ajustar a un valor comprendido
entre 6 y 30 para un disco de 30cm.
Nota:

disco ordinario). Esta posici6n tambi6n se debe
ajustar cadavez que se sustituya la aguja.
1. Presionar la tecla de abertura/cierre OPEN/
CLOSE, tirar hacia afuera de la base deslizable,
colocar un disco de 30cm sobre el plato y ajustar
las rpm correctas mediante el selector de velocidad.
2. Presionar la tecla de inicio START y pasar al
modo de reproducci6n programada (excluyendo
la primera pista del programa). Estimar la
direcci6n y el grado de desplazamiento al mismo
tiempo en la posici6n de descenso.
3. Presionar la tecla de apertura/cierre OPEN/
CLOSE y tirar hacia afuera de la base deslizable. Despu6s presionar la tecla de reproducci6n manual y mover el brazo fonocaptor hacia

c6psula (consultar Figura 9-2) con un pequeflo
destornillador.
o Girar el tornillo de ajuste hacia la derecha si la
aguja desciende en la pista hacia el exterior de la
pista programada.
r Girar el tornillo de ajuste hacia la izquierda si la
aguja desciende hacia el interior de la pista
programada.
o Una vuelta completa del tornillo corresponde a
un desplazamiento de 0,2mm en la posici6n de
descenso.
5. Proceder otra vez con reproducci6n programada
(excluyendo la pista primera del progmma)
y comprobar que la aguja desciende conectamente entre las pistas.
6. Al ajustarse con el disco de prueba GGF-021,
poner el conmutador de sensibilidad en la
posici6n alta HIGH y despu6sajustar el tomillo
para obtener la sefral de salida de lkHz durante
tres o cuatro segundospara pistas despu6sde la
pista primera y esa misma sefral de lkHz se
obtiene tambi6n para pistas despu6s de la pista
sexta.
7. Despu6s de sinalizar el ajuste, activar la reproducci6n programada y comprobar si se obtiene
seflal de solida de lkHz durante tres o cuetro
segundo en pistas posteriores a la primera y
tambi6n. a la sexta.
