SAFETY NOTICE
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 Ω per volt or more sensitivity.
Connect a 1500 Ω 10 W resistor, paralleled by a 0.15 µF
150V AC capacitor between a known good earth ground
(water pipe, conduit, etc.) and all exposed metal parts of
cabinet (antennas, handle bracket, metal cabinet
screwheads, metal overlays, control shafts, etc.).

SAFETY PRECAUTIONS
READING SHOULD NOT EXCEED 0.3V
0.15 µF 150V AC
Test all exposed metal.
Voltmeter Hook-up for Leakage Current Check
Measure the AC voltage across the 1500 Ω 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 reading
exceeding 0.3 V indicates that a dangerous potential
exists, the fault must be located and corrected.
Repeat the above test with the DVD VIDEO RECORDER
power plug reversed.
NEVER RETURN A DVD VIDEO RECORDER 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.
