WARNING TEMP. INDICATOR
The Warning Temp. indicator blinks red to let you know the internal
temperature of the projector exceeds a normal level. If the temperature
goes up further, the projector will be turned off automatically and the
Ready indicator goes out. (The Warning Temp. indicator continues
blinking.) After the cooling-off period, the Ready indicator lights on again
and the projector can be turned on by pressing the POWER button on the
top control or the remote control unit. When you turn on the projector,
the Warning Temp. indicator goes out.
If the Warning Temp. indicator is still blinking, check the following
matters:
– The ventilation slots of the projector may be blocked. In such a case,
reposition the projector so that the ventilation slots are not obstructed.
– The air filters may be clogged with dust particles. Clean them by
following the section “AIR FILTER CARE AND CLEANING” on the next
page.
– If the WARNING TEMP. indicator remains on after performing above
checks, the cooling fans or internal circuits may be malfunctioning.
Contact the service station.
