The openings should never be blocked by placing the product on a bed, sofa, rug, or other similar surface. This product 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. Separate the product from the wall, and keep a distance of more than 10cm.

Power Sources.

This product should be operated only from the type of power source indicated on the marking label. If you are not sure of the type of power supply to your home, consult your product dealer or local power company. For products intended to operate from battery power, or other sources, refer to the operating instructions.

Outdoor Antenna Grounding.

If an outside antenna or cable system is connected to the product, be sure the antenna or cable system is grounded so as to provide some protection against voltage surges and built-up static charges.

Lightning.

For added protection for this product (receiver) during 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 product 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.

5

Overloading.

Do not overload wall outlets and extension cords as this can result in a risk of fire or electric shock.

Heat.

The product should be situated away from heat sources such as radiators, heat registers, stoves, or other products (including amplifiers) that produce heat.

Cleaning.

Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a dry cloth for cleaning.

Servicing.

Do not attempt to service this product 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 product from the wall outlet and refer servicing to qualified service personnel under the following conditions:

-When the power-supply cord or plug is damaged.

-If liquid has been spilled, or objects have fallen into the product.

-If the product has been exposed to rain or water.

-If the product does not operate normally by following the operating instructions. Adjust only those controls that are covered by the operating instructions as an improper adjustment of other controls may result in damage and will often require extensive work by a qualified technician to restore the product to its normal operation.

-If the product has been dropped or the cabinet has been damaged in any way.

-When the product exhibits a distinct change in performance.

Whenever you connect all external A/V equipment to your television, ensure that all equipments are switched off. Also refer to the user manual supplied with your A/V equipment for detail connection instructions and associated safety precaution.

The mains plug is used as the disconnect device. The disconnect device shall remain readily operable.

* The socket-outlet shall be installed near the apparatus and shall be easily accessible.

1-2. Safety precautions for service.

When moving or laying down a TV set, at least two people must be working. Avoid any impact towards the TV set.

Do not leave the broken TV set on for a long time. To prevent any further damages, after check the broken set s condition, make sure to turn the power (AC) off.

When opening the back cover, turn off the power (AC) to prevent electric shock. When a TV set is on, high voltage and high current exist inside the set.

When loosening screws, check the connecting position and type of the screw. Sort out the screws and store them separately. Because screws holding PCB are working as electric circuit grounding, make sure to check if any screw is missing when assembling.

A TV set contains different kind of connector cables. When connected or disconnected connector cables, check the direction and position of the cable beforehand.

When disconnecting connectors, unplug the connectors slowly with care.

Connectors are designed so that if the number of pins or the direction does not match, connectors will not fit. When having problem in plugging the connectors, make sure to check their kind, position, and direction.
