1. IMPORTANT SERVICE NOTES

BEFORE RETURNING THE VIDEO CAMERA RECORDER

Before returning the video camera 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 camera recorder.

2. Inspect all protective devices such as non-metallic control knobs, insulating 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

leakage 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 twoclip leads, connect a IZkohm, IO watt resistor

paralleled by a 0.1 !$F capacitor in series with all exposed metal cabinet parts and a known ground, such as a water pipe or conduit.

UseaVTVM orVOM with IOOOohm pervolt, or higher sensitivity or measure the AC voltage drop across the

resisor (See Diagram).

Move the resistor connection to all exposed metal parts having a return path to the chassis (antenna

connections, metal cabinet, screw heads, knobs and control shafts, etc.) and measure the AC voltage drop across the resistor. Reverse the AC plug (a non

polarized adaptor plug must be used but only for the purpose of completing these checks) on the set and repeat the AC voltage measurements for each exposed metallic 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 camera recorder to the user.

1. NOTES DE SERVICE IMPORTANTES

AVANT DE RENDRE LE MAGNETOSCOPE

Avant de rendre le magnetoscope a I’utilisateur, effectuer

les verifications de securite suivantes.

1. Verifier toutes les gaines de fil pour etre sur que les fils ne sont pas pin& ou que le materiel n’est pas coin& entre le chassis et les autres pieces metalliques dans le magnetoscope.

2. Verifier tous les dispositifs de protection tels que les boutons de commande non metalliques, les materiaux d’isolement, le dos du coffret, les couvercles de compartiment et ajustement ou les boucliers, les reseaux de resistance / condensateur d’isolement,

les isolateurs mecaniques, etc.

3. Pour etre stir qu’il n’y a aucun risque de choc electrique, verifier le courant de fuite de la maniere 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 a pinces et connecter une resistance

de 10 watts I,5 kohm en parallele avec un condensateur de 0,15 PF en serie avec des pieces du coffret metallique exposees et une masse de terre connue telle qu’un tuyau ou un conduit d’eau.

Utiliser un VTVM ou VOM avec une sensibilite de 1000 ohms par volt ou plus ou mesurer la chute de

tension CA entre la resistance (voir diagramme).

Deposer la connexion de la resistance a toutes les pieces metalliques exposees ayant un parcours de

retour au chassis (connexions d’antenne, coffret metallique, t&es devis, boutons et arbres de commande, etc.) et mesurer lachutede tension CAentre la resistance. lnverser lafiche CA (unefiche intermediaire non polarisee doit etre utilisee a seule fin de faire ces verifications.) sur I’appareil et repeter les mesures de tension CA pour chaque piece metallique exposee. Toute lecture de 0,45 V rms (ceci correspond a 0,3 mA rms CA) ou plus est excessive et signale un danger de choc qui doit etre corrige avant de rendre le magnetoscope a son

utilisateur.

4-5-l. Before replacement

The CCD image sensor is more sensitive to electrostatic breakage than CMOS LSI. Therefi

prevent electrostatic damage must be taken when it is replaced. Ground the soldering iron. Ground also the human body, using the wrist strap(through an 1 Mohm resistor). Until the CCDsensor is mounted on the PWB, fit it to the conductive sponge, and short-circuit the foot lead. Take utmost care so that the surface glass of CCD sensor and optical filter are not contaminated and damaged. If any contamination is found, for example fingerprint, wipe it off with silicon paper or clean chamois skin. When replacing the CCD sensor, use the antistaic grounded soldring iron, and perform quickly so!dering.

1) Unsolder the CCD sensor leads from the sensor PWB.

2) Take out the sensor PWB.

3) Remove the two screws (6), and remove the sensor holder and CCD sensor.

4-5-3. Mounting of CCD

1) Place the lens unit upright (since the CCD sensor mount ID faces upward, care must be taken so as not to damage the front lens of unit), put the crystal filter first and then the dust protection rubber into the CCD holder of lens unit. Set the crystal unit with its thin side toward the lens unit.

2) Place the CCD sensor so that the its No. 1 pin is at the right lower (Positioning hole to be at right), and put the CCD sensor into the CCD holder. For smooth and tight fitting, press the right lower part of back of CCD sensor, and then press the left upper part.

Note: Pay attention to the direction of CCD sensor.

3) Place the sensor holder so that its two round markings be visible, and fix the sensor holder with HZ001 3TAFF).

4) Mount the sensor PWB so that the CCD sensor leads go thorough the PWB holes.

5) Solder the CCD sensor lead to the sensor PWB.

Note: Take care not to apply excessive heat.
