9. Warning/Caution/Notice

To prevent possible danger, damage and bodily harm, please consider and observe all

warnings and cautions contained in this paragraph while handling the product or PDP

module only.

This product/PDP module is composed of various kinds of materials such as glass panel,

metals and plastics. A qualified service technician is required for the disposal of the

module.

9.1 Warning

If you do not consider the following warnings, it could result in death or serious injury.

(1) Do not use any other power supply voltage other than the voltage specified in this

product specifications. If you use power voltage deviated from the specifications, it

could result in product failure.

(2) Do not operate or install under the deviated surroundings from the environmental

specification set for the below; in moisture, rain or near water-for example, bath tub,

laundry tub, kitchen sink; in a wet basement; or near a swimming pool; and also near

fire or heater - for example, near or over radiator or heat resistor; or where it is

exposed to direct sunlight; or somewhere like that. If you use the product/PDP module

in places mentioned above, it could result in electric shock, fire hazard or product

failure.

CONFIDENTIAL – DO NOT COPY

File No. SG-0159

Page 2-2

(3) If any foreign objects (e.g. water, liquid and metallic chip or dust) entered the

product/PDP module, the power supply voltage to the product/PDP module must be

turned off immediately. Also, never push objects of any kind into the PDP module as

they may touch dangerous voltage point or make short circuits that could result in fire

hazard or electric shock.

(4) If smoke, offensive smell or unusual noise should come from the product/PDP Module,

the power supplymust be turned off immediately. Also, when the screen fails to display

any picture after the power-on or during operation, the power supply must be turned

off immediately. Do not continue to operate the product/PDP module under these

conditions.

(5) The PDP module is controlled by high voltage about 350V. If you need to handle the

module during operation or just after power off, you must take proper precautions

against electric shock and must not touch the drive circuit portion and metallic part

within 5 minutes. The capacitors in the drive circuit portion remain temporarily

charged even after the power is turned off. After turning off the power, you must be

sure to wait at least one minute before touching the module. If the remain voltage is

strong enough, it could result in electric shock.

(6) Do not disconnect or connect the PDP module’s connector while the power is on, or

immediately after power off. Because the module is operated by high voltage, and the

capacitors in drive circuit remain temporarily charged even after the power is turned

off. If you need to disconnect or reconnect it, you have to wait at least one minute

after power off.

(7) Do not disconnect or connect the power connector by a wet hand. The voltage of the

product/PDP module may be strong enough to cause an electric shock.

(8) Do not damage the power cable. Do not modify it either.

(9) When the power cable or connector is damaged or frayed, do not use it.

(10) When the power connector is covered with dust, please wipe it out with a dry cloth

before the power on.

9.2 Caution

If you do not consider the following cautions, it may result in personal injury or damage

(1)Do not set the product/PDP module on an unstable place, vibrating place and inclined

place. The product/PDP module may fall or collapse, and it may cause serious injury

to a person, and serious damage to the product.

(2) If you need to move the product/PDP module to another place, you must turn off the

power supply and detach the interface cable and power cable from the product/PDP

module beforehand. If the cables are damaged during the transport, it may result in

fire hazard or electric shock. Also if the product/PDP module has dropped or fallen,

it may cause a serious injury to a person.

(3) When you draw or insert the cables, you must turn off the power and do it by holding

the connector. If you forcibly draw the cable, the electric wire in the cable can be

exposed or broken. It may result in fire hazard or electric shock.

(4) When you carry the product/PDP module, it should be done by at least two persons in

order to avoid any unexpected accidents.

(5) When you carry the product, do not hold the speaker and the bottom of black front

bezel to avoid any injuries to a person or damage to the product.

(6) When you detach the speaker net, do not hold the net surface to avoid deformation.

Please hold the edges.

(7) The product has a glass filter on it and the PDP module has a glass-plate. If the

product/PDP module is inflicted with excessive stress – for example: excessive shock,

vibration, bending or heat-shock, the glass could be broken. It may result in a

personal injury. Also, do not press or strike the glass surface.

(8) If the glass is broken, do not touch it with bare hand.

(9) Do not place any objects on the glass panel. It may be the cause of the scratch or

breakage.

File No. SG-0159

Page 2-4

(10) When the black front bezel of the product is covered with dust, please use a dry cloth

to wipe it off and afterwards may apply water or a natural detergent to a piece of soft

cloth or gauze, and wring the cloth tightly to clean.

9.3 Additional notice to the operation and handling of the PDP module

(1) To prevent defect or failure, please check the cable connections and power-supply

condition before power on.

(2) To ensure reliable operation of the module and to protect it from overheating, do not

wrap or cover it with a cloth or like a sheet during power-on. Also don not place the

module in a confined space or any other places of poor ventilation.

(3) The screen is controlled with the display-data signals and synchronized signals. If

noise interferes with those signals, the screen could become unstable and in some

case would cause a failure. Do not place any equipment that generates excessive

EMI/RFI noise near the interface cable of the module.

(3) Be careful not to break the glass panel when you handle the module. Also when

handling the module, you must wear gloves or other hand protection to prevent

injuries that can occur in case the glass is broken.

(4) The glass panel section and drive circuit section of the module are closely connected

and they function as a pair. If the module is arbitrarily recombined, restructured, or

disassembled. AmTRAN will not be responsible for the function, quality or operational

integrity of the modified module. Please do not recombine, restructure, or

disassemble it.

(5) To avoid a possible electric shock, you must make sure that the power supply of this

module is turned off before cleaning. To clean the module’s panel, apply water or a

natural detergent to a piece of soft cloth or gauze, and wring the cloth tightly before

wiping the screen. Make sure that no water comes in contact with the connecting

terminals on the side of the glass panel. Do not use chemical solvents, such as

painter thinner or benzene to clean the glass panel.

(6) When storing the module, you must select an environmentally controlled space.

Avoid any environment in which the temperature or humidity exceeds the

specification values. If you are storing the module for a long period of time, we

recommended that you place the module together with a dehumidifying agent, such

as silica gel, in a moisture-proof bag and keep it in an environmentally controlled

place.

9-4 Notice to handling the glass filter

(1) When the protection film is peeled off, static electricity is generated between the film

and polarizer. This should be peeled off slowly and carefully by people who are

electrically grounded and with wellion-blown equipment or in such a condition, etc.

(2) To clean the glass filter, you may follow the methods of PDP module mentioned

above.

The PDP system block diagram is powered by AC source of 100V~240V AC +/- 10%

@ 50/60 HZ ,another audio power supply that transforms AC source of 100V~240V AC

+/- 10% @ 50/60 HZ into DC 18V source. The DC 18V source supplies the audio AMP

of control board. The digital IC parts of control board is powered by DC 5V from PDP
