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 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 pro-

jector will enter the standby mode.

After “

” appears, be sure to

perform the following measures.

About the lamp indicator

■ The lamp life becomes 0%, when used

for approximately 3,000 hours with “ON”

in “Power Save” or when used for approxi-

mately 2,000 hours with “OFF” in “Power

Save” (see page 69).

■ When the remaining lamp life becomes

5% 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 will automatically

enter 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.
