ADJUSTMENTS 9.1 AUTO.RETU

27、RN l.Insert a small flat-head screwdriver into the player through the opening as shown in Fig. 9-1, and turn the index cam counterclockwise until it stops. 2. Hold ttre tone arm with your hand and move it slowly toward the center spindle. When the needle point of the tonearm reaches at a position 45

28、 to 35 mm from the center of the spindle, the tonealm will no longer move. 3. Insert the screwdriver once again into the player through the opening, tum the index can clock- wise slowly. The tonearm will move gradually to the center spindle. Adjust gap between the center spindle and needle point of

29、the tonearm to about 32 mm. Note; When this gap cannot be adjusted to 32 mrn, the PU plate (B) ae*mbly b not installed correctly. Reinstall the PU plate (B) assembly, and readjust thie gap. 9.2 ARM-ELEVATION ADJUSTMENT The height of the stylus tip from the record sur- face is 8 t 3mm (Fig. 9-2). 9.3

30、 MOTOR ADJUSTMENT 1. Turn the power on and start the turntable platter rotating. 2. Adjust VRl and VR2 in the motor assembly so that the stroboscope appears to be station- ary. Again this adjustment is performed from below. 3. Adjust VR1 for 45 rpm speed, and VR2 for 33 rpm. 4. Always adjust at 33 r

Ins6rer un petit toumevis plat dans Iouverture du tourne-disques. (voir Fig. 9-1) Tourner la came vers la gauche jusqui Iarrt. 2. Prendre le bras de

32、pick-up et le d6placer lente- ment vers le pivot central. Lorsque Iaiguille du bras de pick-up atteint une position entre 45 et 35mm du pivot central, le bras ne bou- gera plus. 3. Ins6rer i nouveau le tournevis dans Iouverture et toumer lentement la came vers la droite. Le bras de pick-up se d6plac

33、era lentement vers le centre. R6gler Ia position de Iaiguille du bras de pick-up i une distance de 32mm du pivot central. Remarque: Si la distance ne peut pas 6tre regl6e d 32mm, cest que la plaque du bras de pich-up (B) nest pas en position conecte. Rdinstaller la plaque de leraemble de bros de pic

34、h-up, et refaire le rdglage de la distance. 9,2 REGLAGE DE LELEVATION DU BRAS Le bout de Iaiguille doit se trouver d une hauteur de 8 t 3mm au-dessus du disque(Fig.9-2). 9.3 REGLAGE DU MOTEUR 1. Brancher le courant et faire tourner la platine. 2. R6gler VR1 et VR2 dans lensemble du moteur pour que l

35、e stroboscope paraisse stationnaire. De nouveau, ce r6glage se fait par dessous. 3. Le r6glage de 45 tpm se fait sur VR1; le 16- glage de 33 tpm se fait sur VR2. 4. Toujours r6gler sur 33 tpm.

Insertar un destomillador pequefro de cabeza plana en el reproductor a trav6s de la abertura tal y como se muestra en la figura g-1, y girar la leva de referencia hacia la izquierda hasta que se detenga. 2. Sostener el brazo fonocaptor co

37、n la mano y moverlo lentamente hacia el pivote central. Cuando la punta de la aguja en el brazo fono- captor llegue a la posici6n de 45 a 35mm desde el centro del pivote, el brazo fonocaptor dejar6 de moverse. 3. Insertar de nuevo el destomillador en el re- productor a trav6s de la abertura, girar l

38、a leva de referencia lentamente hacia la derecha. El brazo fonocaptor se mover6 gradualmente hacia el pivote central. Ajustar el huelgo entre el pivote central y la punta de la aguja del btazo fonocaptor a unos 32mm. NOTA; Cuando este huelgo no pueda ajustarse a 32mm, significa que el ensamble de la

39、 placa PU (B) no estd conectamente instalado. Voluer a instalar el ensamble de la plnca PU (B) y reajustar el huelgo. 9,2 AJUSTE DE LA ELEVACION DEL BRAZO La altura de la punta de la aguja a la super- ficie del disco es de 8 t 3mm (Fig.9-2). 9.3 AJUSTE DEL MOTOR 1. Conectar la alimentaci6n e iniciar

40、 la rotaci6n del plato del giradiscos. Ajustar los VR1 y VP-2 del ensamble del motor de modo que el estroboscopio parezca est6r est6tico. Este ajuste se efect(ra de nuevo desde debajo. Ajustar el VR1 para la velocidad de 45 rpm, y VR2 para la de 33 rpm. Ajustar siempre a 33 rpm. tornillador 2. Fig. 9-1 Ajuste del retorno autom5tico Fig. 9-2 Ajuste de la elevaci6n del brazo 3. 4.
