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.).

AC OUTLET

SAFETY PRECAUTIONS

READING SHOULD NOT EXCEED 0.3V

DVD PLAYER

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 PLAYER power plug

reversed.

NEVER RETURN A DVD PLAYER TO THE CUS-

TOMER WITHOUT TAKING NECESSARY CORREC-

TIVE 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.
