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 manufac-
turer'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.
OUTDOOR ANTENNA GROUNDING
If an outside antenna or cable system is connected to the unit, be sure the antenna or cable system is grounded so as to provide
some protection against voltage surges and built-up static charges. Section 810 of the National Electrical Code, ANSI/NFPA 70,
provides information with respect to proper grounding of the mast and supporting structure, grounding of the lead-in wire to an
antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrodes, and
requirements for the grounding electrode.
SERVICING
Do not attempt to service this unit yourself as opening or removing covers may expose you to dangerous voltage or other hazards.
Refer all servicing to qualified service personnel.

DAMAGE REQUIRING SERVICE
Unplug this unit from the wall outlet and refer servicing to qualified service personnel under the following conditions:
REPLACEMENT PARTS
When replacement parts are required, be sure the service technician uses replacement parts specified by the manufacturer or
those that have the same characteristics as the original parts.
Unauthorized substitutions may result in fire, electric shock or other hazards.
SAFETY CHECK
Upon completion of any service or repairs to this unit, ask the service technician to perform safety checks to determine that the unit
is in proper operating condition.
WALL OR CEILING MOUNTING
The product should be mounted to a wall or ceiling only as recommended by the manufacturer.
HEAT
The product should be situated away from heat sources such as radiators, heat registers, stoves, or other products (including
amplifiers) that produce heat.
DISC TRAY
Keep your fingers well clear of the disc tray as it is closing. It may cause serious personal injury.
CONNECTING
When you connect the product to other equipment, turn off the power and unplug all of the equipment from the wall outlet. Failure
to do so may cause an electric shock and serious personal injury. Read the owner's manual of the other equipment carefully and
follow the instructions when making any connections.
SOUND VOLUME
Reduce the volume to the minimum level before you turn on the product. Otherwise, sudden high volume sound may cause
hearing or speaker damage.
SOUND DISTORTION
Do not allow the product output distorted sound for a longtime. It may cause speaker overheating and fire.
HEADPHONES
When you use the headphones, keep the volume at a moderate level. If you use the headphones continuously with high volume
sound, it may cause hearing damage.
LEASER BEAM
Do not look into the opening of the disc tray or ventilation opening of the product to see the source of the laser beam. It may cause
sight damage.
DISC
Do not use a cracked, deformed, or repaired disc. These discs are easily broken and may cause serious personal injury and
product malfunction.
NOTE TO CATV SYSTEM INSTALLER
This reminder is provided to call the CATV system installer's attention to Article 820-40 of the NEC that provides guidelines for
proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as
close to the point of cable entry as practical.
