cation, “
” will blink 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 further 90 seconds, then the power
will be shut off. After “
” ap- pears, be sure to perform the fol- lowing measures.
About the lamp replacement indicator
■The lamp life becomes 0%, when used for approximately 2,000 hours with “ON” in “Power Save” or when used for approxi- mately 1,500 hours with “OFF” in “Power Save” (see page 69).
■When the remaining lamp life becomes
6% or less, “
” will be displayed on the screen in yellow. When the percentage
becomes 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.
