1.
2.
Parts marked with an are critical parts for safety. Replace only with the one described in the parts
list.
Before returning the DVD product to the customer, make the appropriate leakage current check or
resistance measurements to ensure that exposed parts are properly insulated from the supply circuit.
A leakage current check is recommended for this unit. Plug the AC line cord directly into a 120V 60Hz AC
outlet (do not use an isolation transformer for this check). Use a leakage current tester (Fig. 1) or a
metering system which complies with Underwriters Laboratories (UL 1409). Measure for current from all
exposed metal parts of the cabinet to a known earth ground: particularly, any exposed metal part having a
return path to the chassis. Any current measured must not exceed 0.5mA. Any measurement not within
the limits outlined above are indicative of a potential shock hazard and corrective action must be taken
before returning the unit to the customer.

READ INSTRUCTIONS
All the safety and operating instructions should be read before the unit is operated.
RETAIN INSTRUCTIONS
The safety and operating instructions should be retained for future reference.
HEED WARNINGS
All warnings on the unit and in the operating instructions should be adhered to.
FOLLOW INSTRUCTIONS
All operating and use instructions should be followed.
CLEANING
Unplug this unit from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp
cloth for cleaning.
ATTACHMENTS
Do not use attachments not recommended by the unit’s manufacturer as they may cause hazards.
WATER AND MOISTURE
Do not use this unit near water. For example, near a bathtub, washbowl, kitchen sink, or laundry tub, in a wet
basement, or near a swimming pool.
ACCESSORIES
Do not place this unit on an unstable cart, stand, tripod, bracket, or table. The
unit may fall, causing serious injury, and serious damage to the unit. Use only
with a cart, stand, tripod, bracket, or table recommended by the manufacturer.
An appliance and cart combination should be moved with care. Quick stops,
excessive force, and uneven surfaces may cause the appliance and cart
combination to overturn.
VENTILATION
Slots and openings in the cabinet and in the back or bottom are provided for ventilation, to ensure reliable
operation of the unit, and to protect it from overheating. These openings must not be blocked or covered. The
openings should never be blocked by placing the unit on a bed, sofa, rug, or other similar surface. This unit
should never be placed near or over a radiator or heat source. This unit should not be placed in a built-in
installation such as a bookcase or rack unless proper ventilation is provided or the manufacturer’s instructions
have been adhered to.
POWER SOURCES
This unit should be operated only from the type of power source indicated on the rating plate. If you are not sure
of the type of power supply to your home, consult your appliance dealer or local power company. For units
intended to operate from battery power, or other sources, refer to the operating instructions.
GROUNDING OR POLARIZATION
This unit is equipped with a polarized alternating-current line plug (a plug having one blade wider than the other).
This plug will fit into the power outlet only one way. This is a safety feature. If you are unable to insert the plug
fully into the outlet, try reversing the plug. If the plug should still fail to fit, contact your electrician to replace your
obsolete outlet. Do not defeat the safety purpose of the polarized plug. If your unit is equipped with a 3-wire
grounding-type plug, a plug having a third (grounding) pin, this plug will only fit into a grounding-type power
outlet. This too, is a safety feature. If you are unable to insert the plug into the outlet, contact your electrician to
replace your obsolete outlet. Do not defeat the safety purpose of the grounding-type plug.
POWER-CORD PROTECTION
Power-supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon
or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they
exit from the appliance.
LIGHTNING
To protect your unit from a lightning storm, or when it is left unattended and unused for long periods of time,
unplug it from the wall outlet and disconnect the antenna or cable system. This will prevent damage to the unit
due to lightning and power line surges.
POWER LINES
An outside antenna system should not be located in the vicinity of overhead power lines or other electric light or
power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system,
extreme care should be taken to keep from touching such power lines or circuits, as contact with them might be
fatal.
OVERLOADING
Do not overload wall outlets and extension cords, as this can result in a risk of fire or electric shock.
OBJECT AND LIQUID ENTRY
Do not push objects through any openings in this unit, as they may touch dangerous voltage points or short out
parts that could result in fire or electric shock. Never spill or spray any type of liquid into the unit.
