2. WHEEL SETTING
• Color wheel and phosphor wheel turn phase manually adjustment.
* Please do not usually change setting.
3. MODEL
• This setting is necessary when the A-P.C.Board is replaced with new one.
* If you can copy EEPROM data from old A-P.C.Board, this setting is unnecessary.
* This model setting is effective after power restart.
4. FIRMWARE UPDATE
• Update of firmware can be performed using SD card.
* Grayout will be canceled if SD card containing the file for update is inserted.
* Please refer to SECTION 3 (Firmware update procedure) for the procedure.

4. Notes on service
4. 1. Before service operation
4. 1. 1. Light source
1. The light source of the projector uses lasers.
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 luminance of the light source (LD units) will decrease by duration of usage.
• When the light source is used for approximately 20 000 hours, its luminance is reduced to half its initial luminance.
20 000 hours is the estimated duration, and it varies depending on individual differences and usage conditions.
• If the light source (LD units) goes off or the brightness reduces noticeably, require the replacement it.
3. Static electricity or electrical surges will reduce and degrade the reliability of LD unit.
• When working with the LD unit 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.
4. 1. 2. DMD chip
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.
4. 1. 3. Lithium battery
1. The lithium battery is used for the internal clock in the A-P.C.Board. So when it consumed it must be replaced.
Lithium battery : CR2032
* Use only specified lithium battery.
* Used battery must be scrapped according to the instruction.
2. After replacing the lithium battery, surely set the [DATE AND TIME] on the sub-menu in the main menu [SETUP].
