SAFETY PRECAUTIONS
( MODULE USE AND CONSIDERATIONS IN SERVICING)
PDP Module is a display device to be divided into a Panel part and a Drive part. The Panel part consists of
Electrodes, Phosphor, various dielectrics and gas, and the Drive part includes electronic circuitry and PCB.
When using / handling this PDP Module, pay attention to the below warning and cautions.
Indicates a hazard that may lead to death or injury if the warning is ignored and the product is handled
incorrectly.
Indicates a hazard that can lead to injury or damage to property if the caution is ignored and the product is
handled incorrectly.
■. WARNING
(1) Do not supply a voltage higher than that specified to this product. This may damage the product and may
cause a fire.
(2) Do not use this product in locations where the humidity is extremely high, where it may be splashed with
water, or where flammable materials surround it.
Do not install or use the product in a location that does no satisfy the specified environmental conditions.
This may damage the product and may cause a fire.
(3) If a foreign substance (such as water, metal, or liquid) gets inside the product, immediately turn off the
power.
Continuing to use the product, it is may cause fire or electric shock.
(4) If the product emits smoke, and abnormal smell, or makes an abnormal sound, immediately turn off the
power.
Continuing to use the product, it may cause fire or electric shock.
(5) Do not disconnect or connect the connector while power to the product is on. It takes some time for the
voltage to drop to a sufficiently low level after the power has been turned off.
Confirm that the voltage has dropped to a safe level before disconnecting or connecting the connector.
(6) Do not pull out or insert the power cable from/to an outlet with wet hands. It may cause electric shock.
(7) Do not damage or modify the power cable. It may cause fire or electric shock.
(8) If the power cable is damaged, or if the connector is loose, do not use the product: otherwise, this can
lead to fire or electric shock.
(9) If the power connector or the connector of the power cable becomes dirty or dusty, wipe it with a dry cloth.
Otherwise, this can lead to fire.
(10) PDP Module uses a high voltage (Max.450V dc). Keep the cautions concerning electric shock and do
not touch the Device circuitry when handling the PDP Unit. And because the capacitor of the Device
circuitry may remain charged at the moment of Power OFF, standing by for 1 minute is required in order
to touch the Device circuitry.
