SECTION 1  SERVICE  INFORMATION

<PT-JW130>

1. LD(Laser) unit that is mounted on the inside of the light source unit is classified in Class 4 of the safety standards.

・

Laser light is very danger, can damage the human eye and skin.

・

Please do not perform energization in the state where the lighting block was disassembled.

2. The light source of the projector uses laser diode, the luminance of the light source will decrease by duration of usage.

・

The usage time until when the luminance of the light source decreases by half is approximately 20 000 hours.

・

20 000 hours is the estimated duration, and it varies depending on individual differences and usage conditions.

3. Static electricity or electrical surges will reduce and degrade the reliability of the light source.

・

When working with the LDs take countermeasures to avoid the generation of static electricity, Use or wear appropriate
work clothes, gloves, shoes, grounded wrist straps and other tools to avoid static electricity.

1. The DMD chips are precision-made. Note that in rare cases, pixels of high precision could be missing or always lit.
    Note that such phenomena do not indicate malfunction.
2. Directing a high-power laser beam onto the projection lens surface can damage the DMD chips.

1. The lithium battery is used for the internal clock in the A-P.C. board. So when it consumed it must be replaced.

・

Use only specified lithium battery.

・

Used battery must be scrapped according to the instruction.

2. After replacing the lithium battery, set the [Date and Time] on the sub-menu which in main menu [SETUP].
