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. Depending on the operating environment temperature, luminance of the light source will decrease.
• The higher temperature becomes more luminance of the light source decreases.
3. Luminance of the light source (LD units) will decrease by duration of usage.
• The time until when the luminance of the light source decreases by half differs depending on the setting of the
[PROJECTOR SETUP] menu → [OPERATION SETTING] → [OPERATING MODE].
• The estimated time until when the luminance of the light source decreases by half is as follows.
• The time is an estimated value when the [PICTURE] menu →
[DYNAMIC CONTRAST] is set to [3].
• The time to the half luminance from the original may decrease
or luminance may decrease when changing the [OPERATING
MODE] setting.
• There is possibility not to reach the estimated time effected by
the individual light source characteristics, usage condition or
install condition.
4. Static electricity or electrical surges will reduce and degrade the reliability of LD unit.
• When handling the LD unit, 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-PCB. So when it consumed it must be replaced.
2. After replacing the lithium battery, surely set the [DATE AND TIME] on the sub-menu in the main menu [PROJECTOR
SETUP].
Lithium battery : CR2032
* Use only specified lithium battery.
* Used battery must be scrapped according to the instruction.
