    - 4 - 2. Safety Precautions When servicing of PDP Module, it should be not enforced into another way aside next rule, or a unaccustomed person should not repairing. When using/handling this PDP Module, pay attention to the below warning and cautions.
  • Page 5 - 5 - charged at the moment of Power OFF, standing by for 1 minute is required in order to touch the Device circuitry. 2) CAUTIONS (1) Do not place this product in a location that is subject to heavy vibration, or on an unstable surface such as an inclined surface.
  • Page 6 - 6 - internal Drive circuitry. And because the PDP Module is driven by high voltage, it must avoid conductive materials. (14) If inserting components or circuit board in order to repair, be sure to fix a lead line to the connector before soldering. (15) If inserting high-power resistor (metal-oxide film resistor or metal film resistor) in order to repair, insert it as 10mm away as from a board.
