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, make
sure you use an appropriate power cord for
the country 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 69 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.
• Even if you unplug the power cord after
projector operation, the cooling fan con-
tinues to run for a while. When you place
the projector into the storage case, make
sure that the cooling fan has stopped.
Optional lens installation
■ For installing an optional lens, refer to “At-
taching the Optional Lens” on page
77
or the
lens installation manual (supplied with the
optional lens).
■ Remove the optional lens when carrying the
projector. Carrying the projector with an op-
tional lens attached can cause the projector
to be damaged by vibration or other factors.
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.
■ Set up the projector where air will not stay
near its exhaust vent. In order to avoid allow-
ing the heat from the exhaust vent to enter
the intake vent area, leave at least more than
11
13
/16 inches (30 cm) of space between the
intake vent and the surrounding walls or ob-
jects.
■ 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 69 and 70.). 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, take care not to subject
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, make cer-
tain you 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, ensure you at-
tach the lens cap or dustproof cap to the pro-
jector. (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 owner’s manuals of the pro-
jector and the equipment to be connected for
instructions on how to make the connections.
