Attention
•
When you purchase the projector, a protective cap is installed in the lens unit
installation section. Install the protective cap when you are not using the
projector. If dust or dirt enter the projector, projection quality deteriorates
and it could cause a malfunction.
•
When a high-powered laser beams through the surface of the projection lens
or the built-in camera, it can cause a malfunction. If the laser beams through
the surface of the projection lens or the built-in camera, block the laser beam
with non-permeable or incombustible aluminum foil or metal plates such as
iron to protect the projection lens and the built-in camera.
•
Try not to touch the lens section with your hand or fingers. If fingerprints or
oils are left on the surface of the lens, projection quality deteriorates.
•
Store the projector with the protective cap installed. If the projector is stored
without the protective cap, dust and dirt may get inside the projector and
cause malfunctions or lower the quality of projection.
•
When storing, make sure you remove the batteries from the remote control.
If the batteries are left in the remote control for an extended period of time,
they may leak.
•
When using the projector in smokey environments such as at events and so
on, make sure you replace the air filter within 24 hours.

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, it can cause a malfunction in the LCD panel. If the laser can beam
through the surface of the projection lens, block the laser beam with
non-permeable or incombustible aluminum foil or metal plates such as
iron to protect the projection lens.
•
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
.

About light source calibration
- Every time the usage time reaches 100 hours, calibration starts
automatically for the light source when the projector is turned off.
However, light source calibration does not start automatically in the
following situations.
•
Within 20 minutes of turning on the projector
•
When using the Shutter function
•
Within 20 minutes of releasing the Shutter function
•
When the projector is used continuously for over 24
hours
•
When using direct shutdown
- When performing light source calibration, the difference between the
white balance and the brightness level for the light source is corrected.
