IMPORTANT INFORMATION
WARNING : TO REDUCE THE RISK OF FIRE AND ELECTRIC SHOCK, DO NOT EXPOSE THIS
PRODUCT TO RAIN OR MOISTURE.
Please use a screen saver to prevent burning of an after-image on the screen.
Electrical energy can perform many useful functions. This unit has been engineered and manufactured to assure your personal safety. But IMPROPER USE CAN RESULT IN POTENTIAL ELECTRICAL SHOCK OR FIRE HAZARD. In order not to defeat the safeguards incorporated into this unit, observe the following basic rules governing its installation, use and service. Please read these "Important Safeguards" carefully before use.
Read all the safety and operating instructions before operating the unit. Retain the safety and operating instructions for future reference. Adhere to all warnings on the unit and in the operating instructions. Follow all operating instructions. Unplug the unit from the wall outlet before cleaning. Do not use liquid or aerosol cleaners. Use a damp cloth for cleaning. Do not use attachments not recommended by the manufacturer as they may be hazardous. Do not use the unit near water. Do not use the unit immediately after moving it from a low temperature to a high
temperature environment, as this causes condensation, which may result in fire, electric shock, or other hazards.
Do not place the unit on an unstable cart, stand, or table. The unit may fall, causing serious injury to a child or adult, and
serious damage to the unit. Mount the unit according to the manufacturer's instructions, using the mount recommended by the manufacturer.
When the unit is used on a cart, avoid quick stops, excessive force, and uneven
surfaces which may cause the unit and cart to overturn, damaging the unit or causing possible injury to the operator. When transporting by car, place the unit as shown in the figure.
Slots and openings in the cabinet are provided for ventilation. These ensure reliable operation and protect the unit 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 similar surface. The unit should not be placed in a built - in installation such as a bookcase or rack unless proper ventilation is provided and the manufacturer's instructions are adhered to.) For proper ventilation, separate the unit from other equipment, which may obstruct ventilation. Keep the unit at least 10cm from other equipment.
Operate only with the type of power source indicated on the label. If you are not sure of the type of power supply to your
home, consult your dealer or local power company.
This unit is equipped with a three-wire plug. This plug will fit only into a grounded power outlet. If you cannot insert the plug
into the outlet, have an electrician install the proper outlet. Do not defeat the safety purpose of the grounded plug.
Route power cords so that they are not likely to be walked on or pinched by items placed on or against them. Pay
particular attention to cords at doors, plugs, receptacles, and where they exit from the unit.
For added protection during a lightning storm, or when the unit is left unattended and unused for long periods of time,
unplug it from the wall outlet and disconnect the cabling. This will prevent damage to the unit by lighting and power line surges.
Do not overload wall outlets, extension cords, or convenience receptacles on other equipment as this can result in fire or
electric shock.
Never push objects of any kind into this unit through openings as they may touch dangerous voltage points or short-circuit
parts that could result in a fire or electric shock. Never spill liquid of any kind onto the unit.
- 2 -
Do not attempt to service this unit yourself as opening or removing covers may expose you to dangerous voltages and
other hazards. Have all service done by qualified service personnel.
Unplug this unit from the wall outlet and have it serviced by qualified service personnel in the following cases:
a) If the power supply cord or plug is damaged. b) If liquid has been spilled, or objects have fallen onto the unit. c) If the unit has been exposed to rain or water. d) If the unit does not operate normally by following the operating instructions. Adjust only those controls that are
covered by the Operation Manual, as improper adjustment of controls may result in damage and will often require extensive work by a qualified technician to restore the unit to normal operation.
e) If the unit has been dropped or damaged in any way.
A distinct change in performance indicates that service is required.
When required, be sure the service technician uses replacement parts specified by the manufacturer or parts with the
same characteristics as the original parts. Unauthorized substitutions may result in fire, electric shock, or other hazards.
Upon completion of any service of repairs, ask the service technician to perform safety checks to determine that the
unit is in proper operating condition.
Place the unit more than one foot away from heat sources such as radiators, heat registers, stoves, and other devices
(including amplifiers) that produce heat.
When connecting other devices such as VCR's and personal computers, turn off the power to this unit to protect
against electric shock.
Do not place combustibles such as cloth, paper, matches, aerosol cans or gas lighters that prevent special hazards
when overheated behind the cooling fan.
Use only the accessory cord designed for this unit to prevent shock.
The power supply voltage rating of this unit is AC100-240V, but the attached power cord conforms to the following power supply voltage. Use only the Power Cord designated by our dealer to ensure Safety and EMC.
When used with other power supply voltages, the power cable must be changed. Consult your local dealer.
