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, ensure
to use an appropriate power cord for the coun-
try you are in.
Temperature monitor function
■
If the projector starts to over-
heat due to setup problems or
blockage of the air vents, “ ”
and “ ” will illuminate in
the lower left corner of the picture. If the tem-
perature continues to rise, the lamp will turn off,
the temperature warning indicator on the pro-
jector will blink, and after a 90-second cooling-
off period the projector will enter the standby
mode. Refer to “Maintenance Indicators” on
page 91 for details.
Info
• The cooling fan regulates the internal tem-
perature, and its performance is automati-
cally controlled. The sound of the fan may
change during projector operation due to
changes in the fan speed. This does not
indicate malfunction.
• Do not unplug the power cord during pro-
jection or cooling fan operation. This can
cause damage due to rise in internal tem-
perature, as the cooling fan also stops.
Optional lens installation
■ Be sure to have service personnel install the
optional lenses.
Do not block the intake and exhaust
vents.
■ Allow at least 11
13
/16 inches (30 cm) of space
between the exhaust vent and the nearest
wall or obstruction.
■ Ensure that the intake vents and the exhaust
vent are not obstructed.
■ If the cooling fan becomes obstructed, a pro-
tection circuit will automatically put the pro-
jector into standby mode to prevent overheat
damage. This does not indicate a malfunc-
tion (See pages 91 and 92.). Remove the pro-
jector power cord from the wall outlet and wait
at least 10 minutes. Place the projector where
the intake and exhaust vents are not blocked,
plug the power cord back in and turn on the
projector. This will return the projector to the
normal operating condition.
Caution regarding usage of the projector
■ When using the projector, ensure not to sub-
ject it to hard impact and/or vibration, as this
can result in damage. Take extra care with the
lens. If you are not to use the projector for a
long time, ensure to unplug the power cord from
the wall outlet, and disconnect any other cables
connected to it.
■ Do not use the projector while holding the
lens.
■ When storing the projector, ensure to attach
the lens cap to the projector. (See page 13.)
■ Do not expose the projector to direct sunlight
or near heat sources. The projector may
change color or become deformed.
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.
