IMPORTANT SERVICE NOTES
BEFORE RETURNING THE DVD PLAYER
Beforereturning the DVDplayerto 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 DVD player.
2. Inspect all protective devices such as non-metallic
control knobs, insulation materials, cabinet backs,
adjustmentandcompartmentcoversorshields,isola-
tion resistor/capacitor networks, mechanical insula-
tors 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
resistorparalleledby a0.15µFcapacitorinserieswith
all exposed metal cabinet parts and a known earth
ground, such as a water pipe or conduit.
●UseanDVMorVOMwith1000ohmpervolt,orhigher
sensifivity measure the AC voltage drop across the
resistor (See Diagram).
●Move the resistor connection to earth exposed metal
parthavingareturnpathtothechassis(metalcabinet,
screw heads, knobs and control shafts, etc.) and
measure the AC voltage drop across the resistor.
