Safety Warning and Cautions
a
• About the LCD panel
- The LCD panel may contain pixels that are missing or appear bright all
the time. This is not a sign of an error.
- When a high-powered laser beams through the surface of the projection
lens even when it is not being used, it can cause a malfunction in the
LCD panel. Attach the lens cover when storing the projector.
• About the light source
The projector uses a laser as the light source. The laser has the
following characteristics.
- Depending on the surroundings, the brightness of the light source may
decline. The brightness declines a lot when the temperature gets too
high.
- The brightness of the light source declines the longer it is used. You can
change the relationship between usage time and decline in brightness in
Brightness Settings.
s "Relationship between Brightness Level and usage time"
• Light Source Calibration
- Whenever the usage time reaches 100 hours, calibration starts
automatically for the light source when the projector is turned off.
However, this does not start automatically when the projector is used
continuously for more than 24 hours, or when direct shutdown is used
regularly. Set Light Source Calibration in the scheduling function.
s "Scheduling Function"
- When performing light source calibration, the difference between the
white balance and the brightness level for the light source is corrected.
