About the temperature warning indicator
If the temperature inside the pro- jector increases, due to blockage of the air vents, or the setting lo-
cation, “
” will illuminate in
the lower left corner of the picture. If the temperature keeps on rising, the lamp will turn off and the tem- perature warning indicator will blink, the cooling fan will run for a further 90 seconds, and then the power will be shut off. After
“
” appears, be sure to per- form the following measures.
■The lamp life becomes 0%, when used for approximately 4,500 hours with “Eco Mode” or when used for approximately 3,000 hours with “Standard Mode” (see page 45).
■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 as well. At this time, the lamp replacement indicator will illu- minate in red.
■If you try to turn on the projector a fourth time without replacing the lamp, the pro- jector will not turn on.
