About the temperature warning indicator
If the temperature inside the projector increases, due to blockage of the air vents, or the
setting location, “
” will
illuminate 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 a further 90 seconds, and then the projector will enter the standby mode. After
“
” appears, be sure to perform the following measures.
■The lamp life becomes 0%, when used for approximately 4,000 hours with “Eco Mode” or when used for approximately 2,000 hours with “Standard Mode” (see page 43).
■When the remaining lamp life becomes
5% or less, “
” (yellow) will be displayed on the screen. When the percentage be-
comes 0%, “
” will change to “
” (red), the lamp will automatically turn off and then the projector will automatically en- ter the standby mode. At this time, the lamp indicator will illuminate in red.
■If you try to turn on the projector a fourth time without replacing the lamp, the pro- jector will not turn on.
