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.
