4. Notes on service
4. 1. Before service operation
4. 1. 1. Light source
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. Depending on the operating environment temperature, the luminance of the light source will decrease.
The higher the temperature becomes, the more the luminance of the light source decreases.
3. The luminance of the light source 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 [PROJEC-
TOR SETUP] menu → [OPERATION SETTING] → [OPERATING MODE].
• The estimated time until when the luminance of the light source decreases by half is as follows.
OPERATING MODE
HIGH
NORMAL
LONG LIFE1
LONG LIFE2
LONG LIFE3
• The foregoing time is a rough estimate when the projector is used without changing the settings of [OPERATING MODE]
and [CONSTANT MODE], and will vary depending on individual differences and usage conditions.
4. 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. Air filter unit
1. Make sure that the air filter unit is properly attached before using the projector. If it is not properly attached, the projector
will suck in dirt and dust causing a malfunction.
2. The cleaning and replacement cycle of the air filter unit varies depending on the usage environment.
3. Replace the air filter unit if it is damaged or if the dirt does not come off even after washing.

[Note]
• Air filter replacement is recommended after cleaning the unit two times.
The dust-proof properties may be reduced after each cleaning.
• Do not disassemble the air filter unit.
• When using the "Smoke cut filter" or "Log life filter unit", make sure to setup the filter type with menu [Main menu] - [Projec-
tor setup] - [Filter setting] - [Filter type] according to the type mounted on the projector. Also, when you finish using it, return
the filter setting to [Normal].
