LEAKAGE CURRENT CHECK
Plug the AC line cord directly into a 120V AC outlet (do
not use an isolation transformer for this check). Use an
AC Voltmeter, having 5000 W per volt or more sensitiv-
ity. Connect a 1500 W 10 W resistor, paralleled by a
0.15 µF 150V AC capacitor between a known good
earth ground (water pipe, conduit, etc.) and all ex-
posed metal parts of cabinet (antennas, handle
bracket, metal cabinet, screwheads, metal overlays,
control shafts, etc.).
Measure the AC voltage across the 1500 W resistor.
The test must be conducted with the AC switch on and
then repeated with the AC switch off. The AC voltage
indicated by the meter may not exceed 0.3 V. A read-
ing exceeding 0.3 V indicates that a dangerous poten-
tial exists, the fault must be located and corrected.
Repeat the above test with the VCR power plug
reversed.
NEVER RETURN A VCR TO THE CUSTOMER
WITHOUT TAKING NECESSARY CORRECTIVE
ACTION.
The lightning flash with arrowhead symbol, within an
equilateral triangle, is intended to alert the user to the
presence of uninsulated "dangerous voltage" within
the product's enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to
persons.
The exclamation point within an equilateral triangle is
intended to alert the user to the presence of important
operating and maintenance (servicing) instructions
in the literature accompanying the appliance.
