If the temperature protector is activated
If the projector's internal temperature rises abnormally, the lamp turns off and the temperature indicator flashes
(repeatedly in cycles of 2).
It may happen that the projector's temperature protector is simultaneously activated and the projector's power turns
off.
If this happens, do the following:
- Unplug the power cord from the power outlet.
- If using in a place where the surrounding temperature is high, move the projector to a different, cool place.
- If there is dust in the ventilation holes, clean. (→ pages
- Wait as such about 1 hour for the projector's internal temperature to lower.

The temperature protector has been activated. If the
room temperature is high, move the projector to a cool
place. If the TEMP. indicator still be flashing when the
projector is used at operating temperatures, contact an
NEC projector customer support center.
The usage environment temperature is lower than the
projector's operating temperature (0°C). In that case,
raise the usage environment temperature to a 0°C or
higher and turn on the projector. If the projector is turned
on at around 0°C, it may take 5 minutes to warm up the
projector. During this warm-up period the TEMP. indicator
will flash. When the warm-up is completed, the TEMP.
indicator will go off.
