■ When turning off the projector, the cooling fan
runs to decrease the internal temperature for
a while. Unplug the power cord after the cool-
ing fan stops. The period the cooling fan runs
will vary, depending on the circumstances and
the internal temperature.
Caution regarding usage of the projector
■ When using the projector, be sure not to sub-
ject it to hard impact and/or vibration, as this
can result in damage. Take extra care with
the lens. Before moving the projector, be sure
to unplug the power cord from the wall outlet,
and disconnect any other cables connected
to it.
■ Do not carry the projector by holding the lens.
■ When storing the projector, re-attach the lens
cap. (See page 11).
■ Do not expose the projector to direct sunlight
or place next to heat sources. Doing so may
affect the cabinet color or cause deformation
of the plastic cover.
Other connected equipment
■ When connecting a computer or other audio-
visual equipment to the projector, make the
connections AFTER unplugging the power
cord of the projector from the AC outlet and
turning off the equipment to be connected.
■ Please read the operation manuals of the pro-
jector and the equipment to be connected for
instructions on how to make the connections.
Info
• The cooling fan regulates the internal tem-
perature, and its performance is automatically
controlled. The sound of the fan may change
during projector operation due to changes in
the fan speed. This does not indicate malfunc-
tion.
• Do not unplug the power cord during projec-
tion or cooling fan operation. This can cause
damage due to rise in internal temperature,
as the cooling fan also stops.
Using the projector in other countries
■ The power supply voltage and the shape of
the plug may vary depending on the region
or country you are using the projector in.
When using the projector overseas, be sure
to use an appropriate power cord for the coun-
try you are in.
Temperature monitor function
■
If the projector starts to overheat due to setup
problems or blockage of the air vents, “ ” and
“ ” will illuminate in the lower left corner
of the picture. If the temperature continues to
rise, the lamp will turn off, the temperature warn-
ing indicator on the projector will blink, and after
a 90-second cooling-off period the projector will
enter standby mode. Refer to “Maintenance In-
dicators” on page 52 for details.
