SECTION 1  SERVICE  INFORMATION

< RZ670/RW630 >

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.

・

When using the projector at elevations lower than 2 700 m (8 858') above sea level, and the operating environment
temperature becomes 35 °C (95 °F) or higher, the luminance of the light source may decrease.

・

When using the projector at elevations between 2 700 m (8 858') and 4 200 m (13 780'), and the operating 
environment temperature becomes 25 °C (77 °F) or higher, the luminance of the light source may decrease.

・

The higher the temperature becomes, the more the luminance of the light source decreases.

3. The 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 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 ndividual 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.

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.

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

To revert to the factory default password (AAAA), perform the following operations while the screen asking for a control 
device password input is displayed.

1) Press the [AUTO SETUP] button on the remote control for at least two seconds.
2) Press s for at least two seconds.

Initial password　: Press [ 　　　　　　　 ] in order, and　press the [ENTER] button.
