f Directing a high-power laser beam onto the projection lens surface can damage the DLP chips.
rLight source
The light source of the projector uses lasers, and has the following characteristics.
f 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.
f 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
[PROJECTOR SETUP] menu → [ECO MANAGEMENT] → [OPERATING MODE].
The estimated time until when the luminance of the light source decreases by half is as follows.
(The time is estimated when the [PICTURE] menu → [DYNAMIC CONTRAST] is set to [ON].)
g When [OPERATING MODE] is set to [NORMAL] or [SILENT]: Approximately 20 000 hours
g When [OPERATING MODE] is set to [ECO]: Approximately 24 000 hours
This time is rough estimate when the projector is used without changing the [OPERATING MODE] setting, and
will vary depending on individual difference and usage condition.
If brightness is noticeably reduced and the light source does not turn on, ask your dealer to clean inside the
projector or replace the light source unit.
rComputer and external device connections
When connecting a computer or an external device, read this manual carefully regarding the use of power cords
and shielded cables as well.
