1. IMPORTANT SAFEGUARDS AND PRECAUTIONS

1. IMPORTANT SERVICE NOTES

BEFORE RETURNING THE VIDEO CASSETTE RECORDER

Before returning the video cassette recorder to the user, perform the following safety checks.

1. Inspect all lead dress to make certain that leads are not pinched or that hardware is not lodged between the chassis and other metal parts in the video cassette recorder.

2. Inspect all protective devices such as non-metallic control knobs, insulation materials, cabinet backs, adjustment and compartment covers or shields, isolation resistor/capacitor networks, mechanical insulators etc.

3. To be sure that no shock hazard exists, check for current in the following manner.

● Plug the AC line cord directly into a 120 volt AC outlet (Do not use an isolation transformer for this test).

● Using two clip leads, connect a 1.5k ohm, 10 watt resistor paralleled by a 0.15µF capacitor in series with all exposed metal cabinet parts and a known earth ground, such as a water pipe or conduit.

● Use an SSVM or VOM with 1000 ohm per volt, or higher, sensitivity or measure the AC voltage drop across the resistor (See Diagram).

● Move the resistor connection to earth exposed metal part having a return path to the chassis (antenna, metal cabinet, screw heads, knobs and control shafts,

etc.) and measure the AC voltage drop across the resistor. Reverse the AC plug on the set and repeat AC voltage measurements for each exposed part. Any reading of 0.45V rms (this corresponds to 0.3mA rms AC.) or more is excessive and indicates a potential shock hazard which must be corrected before returning the video cassette recorder to the owner.

1. NOTES DE SERVICE IMPORTANTES

AVANT DE RENDRE LE MAGNETOSCOPE Avant de rendre le magnétoscope à l’utilisateur, effectuer

les vérifications de sécurité suivantes.

1. Vérifier toutes les gaines de fil pour être sûr que les fils ne sont pas pincés ou que le matériel n’est pas coincé entre le châssis et les autres pièces métalliques dans le magnétoscope.

2. Vérifier tous les dispositifs de protection tels que les boutons de commande non métalliques, les matériaux d’isolement, le dos du coffret, les couvercles de compartiment et ajustement ou les boucliers, les réseaux de résistance / condensateur d’isolement, Ies isolateurs mécaniques, etc.

3. Pour être sûr qu’il n’y a aucun risque de choc électrique, vérifier le courant de fuite de la maniére suivante.

● Brancher le cordon d’alimentation secteur directement dans une prise de courant de 120 volts. (Ne pas utiliser de transformateur d’isolement pour cet essai).

● Utiliser deux fils à pinces et connecter une résistance

● Utiliser un VTVM ou VOM avec une sensibilité de 1000

● Déposer la connexion de la résistance à toutes les

de 10 watts 1,5 kohm en parallèle avec un condensateur de 0,15 µF en série avec des pièces du coffret métallique exposées et une masse de terre connue telle qu’un tuyau ou un conduit d’eau.

ohms par volt ou plus ou mesurer la chute de tension CA entre la résistance (voir diagramme).

pièces métalliques exposées ayant un parcours de

retour au châssis (connexions d’antenne, coffret métallique, tétes de vis, boutons et arbres de commande, etc.) et mesurer la chute de tension CA entre la résistance. Inverser la fiche CA (une fiche intermédiaire non polarisée doit être utilisée à seule fin de faire ces vérifications.) sur l’appareil et répéter les mesures de tension CA pour chaque piéce métallique exposée. Toute lecture de 0,45 V rms (ceci correspond à 0,3 mA rms CA) ou plus est excessive et signale un danger de choc qui doit être corrigé avant de rendre le magnétoscope à son utilisateur.

7. EXPLANATION OF MECHANISM

(1)Tray loading mechanism

When the tray loading motor rotates clockwise, motion is transmitted to the slide rack D through the intermediate gear 1 A , intermediate gear 2 B and tray pinion C , resulting in insignificant motion in the arrow direction. The slide rack is linked with the operating chassis. It lowers the pickup mechanism. The protrusion of slide rack E is linked with the tray through the groove at the rear side of tray, so that the tray is pushed ahead a little. When the tray is pushed out, the slide rack is disconnected from the tray pinion, and at the same time the gear at the rear side of tray is connected with the tray pinion, and the tray is pushed ahead. When the tray is pushed out fully, the slide rack moves further in the arrow direction through the groove at the rear side of tray. The tray position detection switch F is turned on, and the tray loading motor stops. When the tray closes the operation is as follows. If the tray OPEN/CLOSE button or tray is pressed and the detection switch is turned off, the tray loading motor rotates counterclockwise, so that the tray is retracted. When the detection switch is turned on again, the tray loading motor stops.

This groove is linked with trhe pawl of pickup mechanism

(2)Pickup feed mechanism

When the sled motor A rotates, the rack C moves through the sled pinion B so that the pickup D is moved to the internal or external periphery. When it is moved to the innermost periphery, the position detection switch E is pushed by the rack, so that the position of pickup is initialized.

(3)Disc rotation mechanism

Spindle motor

The spindle motor is used to rotate. IC701 is used to control. When the spindle motor is replaced, replace the spindle unit.

High order byte data input/output: The function is the same as that of low order byte data input/output. Operative only in x16 mode. x8 mode: Float state DQ15/A-1 is address. Chip enable: Device control logic, input buffer, decoder and sense amp. are activated. Chip becomes active only when CE# is “Low”. Reset/Power down: If RP# is set to “Low”, the control circuit is initialized when power is turned on. Hence, the RP#pin is set to “Low”. When power is turned on or off or in case of fluctuation it is kept at “Low” so as to protect data from noise. When RP# is in “Low” state, the device is in deep power down state. 480 ns is required to recover from the deep power down state. If the RP# pin becomes “Low”, the whole chip operation is interrupted and reset. After recovery the device is set to array read state. Output enable: When OE# is set to “Low”, data is output from the DQ pin. When OE# is set to “High”, the DQ pin is set to float state. Write enable: Command user interface, data Q register and address Q latch access is controlled. In “Low” state WE# becomes active. At rise edge the address and data are fetched. Ready/busy: The state of internal write state machine is output. In “Low” state it is indicated that the write state machine is in operation. If the write state machine waits for next operation instruction, erase is suspended or it is in deep power down state, the RY/BY# pin is in float state. Byte enable: When BYTE# is set to “Low”, the device is set to the x8 mode. At this time

-DQ15 pin becomes float state. Address A-1 selects high order/low order byte.

When BYTE# is “High”, the device is set to the x16 mode. The A-1 input circuit is disabled.
