IMPORTANT SERVICE NOTES

WARNING :TO REDUCE THE RISK OF FIRE OR ELEC-TRIC SHOCK, DO NOT EXPOSE THIS AP-PLIANCE TO RAIN OR MOISTURE.

RISK OF ELECTRIC SHOCKDO NOT OPEN

CAUTION

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK. DONOT REMOVE COVER. NO USER-SERVICEABLEPARTS INSIDE. REFER SERVICING TO QUALIFIEDSERVICE PERSONNEL.

This symbol warns the user of uninsulated voltagewithin the unit that can cause dangerous electric shocks.

This symbol alerts the user that there are importantoperating and maintenance instructions in the literatureaccompanying this unit.

This symbol mark means fast operating fuse.For continued protection against risk of fire, replaceonly with same type fuse F901 (3.0A, 125V).

CAUTION:

BEFORE RETURNING THE VIDEO CASSETTERECORDER

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

1. Inspect all lead dress to make certain that leads arenot pinched or that hardware is not lodged betweenthe chassis and other metal parts in the video cassetterecorder.

2. Inspect all protective devices such as non-metalliccontrol knobs, insulation materials, cabinet backs,adjustment and compartment covers or shields, isola-tion resistor/capacitor networks, mechanical insula-tors etc.

3. To be sure that no shock hazard exists, check forcurrent 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 wattresistor paralleled by a 0.15µF capacitor in series withall exposed metal cabinet parts and a known earthground, such as a water pipe or conduit.

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

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

Many electrical and mechanical parts in video cassette recorder have

special safety-related characteristics. These characteristics are often

not evident from visual inspection nor can the protection afforded by

them necessarily be obtained by using replacement components rated

for higher voltage, wattage, etc. Replacement parts which have these

special safety characteristics are identified in this manual; electrical

components having such features are identified by " å " and shaded

areas in the Replacement Parts Lists and Schematic Diagrams.

The use of a substitute replacement part which does not have the same

safety characteristics as the factory recommended replacement parts

shown in this service manual may create shock, fire or other hazards.

"HOW TO ORDER REPLACEMENT PARTS"To have your order filled promptly and correctly, please furnish

the following informations.

De nombreuses pièces électriques et mécaniques de magnétosco-

pes présentent des caractéristiques particulières de sécurité.

Ces caractéristiques ne sont pas toujours évidentes à l’inspection

visuelle et la protection qu’elles assurent ne peut pas toujours être

obtenue par des pièces de rechange étalonnées à un régime de

tension, une puissance, etc. superieurs. Les pièces de rechange qui

présentent ces caractéristiques spéciales de sécurité, sont identifiées

dans ce manuel: les pièces électriques qui présentent ces particularités,

sont repérée par la marque " å " et sont hachurées dans les listes de

pièces et dans les diagrammes schématiques.

La substitution d’une pièce de rechange par une autre qui ne présente

pas les mêmes caractéristiques de sécurité que la pièce recommandée

par l’usine et repérée dans ce manuel de service, peut provoquer une

électrocution, un incendie ou tout autre sinistre.
