  1. Precautions and Safety Notices


  1. When replacing the lamp, use care to avoid burns to your fingers. The lamp becomes very hot
     during operation.

  2. Never touch the lamp with your fingers as body oil transferred to the lamp can damage the
     lamp's useful life.

  3. Never drop the lamp or jar it in any manner. This may cause the lamp to burst.

  4. This projector is provided with a high voltage circuit for the lamp. Do not touch any electric
     part or component after the projector has been turned on and is operating. Doing so could
     induce a severe shock causing injury or death.

  5. Do not touch the exhaust fan, nor block its air flow, during operation, as the fan is hot.

  6. The LCD module assembly can be easily damaged during service. If replacing the LCD
     Lens/Prism assembly, do not hold the FPC of the LCD module assembly.

  7. Use only the cables which are included with the projector, or are specified in this manual.
