• 

The warning lights on the projector indicate problems inside the projector.

• 

There are three warning lights: a TEMPERATURE WARNING indicator that warns you
when the projector is too hot, and two LAMP REPLACEMENT indicators that warn you
when to change a lamp.

• 

If a problem occurs, either the temperature warning indicator or the lamp replacement
indicator will illuminate red, and the power will turn off. After the power has been turned
off, follow the procedures given below.

If the temperature inside the projector increases, due
to blockage of the air vents, or the setting location,
“TEMP ” will blink in the lower left corner of the
picture. If the temperature keeps on rising, the lamp
will turn off and the temperature warning indicator
will blink, the cooling fan will run for further 90
seconds, then the power will be shut off. After
“TEMP” appears, be sure to perform the following
measures.

• 

When the remaining lamp life becomes 900
hours or more, “Lamp Warning Icon” will be
displayed on the screen in yellow. When the
hours reach 1000,  “Lamp Warning Icon” will
change to “Lamp Warning Icon” (red), the lamp
will automatically turn off and then the projector
as well. At this time, the lamp replacement
indicator will illuminate in red.

• 

If you try to turn on the projector a fourth time
without replacing the lamp, the projector will not
turn on.
