IMPORTANT SERVICE NOTES
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.
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,

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.
De nombreuses pièces électriques et mécaniques de magnétoscopes 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.
