The projector provides 3 temperature sensor ICs and 1 wind sensor on the intake duct. These devices are monitoring 
the surrounding temperature of the lamp, panel and intake duct, and the wind sensor is monitoring airflow passed 
through the air filter in the intake duct.
- Internal temperature sensor A (IC1692) (around the Intake duct) 
- Internal temperature sensor B (IC1816) (around the lamp house)
- Internal temperature sensor C (IC1814) (around the panel/prism)
- Wind sensor D (S901) (intake duct)

The projector is shut down and the < TEMP> indicator is blinking red.
When the temperature inside the projector reaches a certain level, the <TEMP> indicator starts blinking slowly. If the 
temperature rises moreover, the projector will be automatically shut down to protect the inside of the projector, and 
the <TEMP.> indicator is blinking fast and the <ON(G)/STANDBY(R)> indicator lights in orange. When the projector 
has cooled down enough (to its normal operating temperature), the <ON(G)/STANDBY(R)> indicator lights in red and 
the projector can be turned on again by pressing the   button.

the projector is turned on again, the <TEMP> indicator stops blinking. 
Check the items below
- Remove dust around the air filter.
-  Ventilation slots of the projector are blocked. In such an event, reposition the projector so that ventilation slots are 
not obstructed.
-  Check if projector is used at higher temperature place (Normal; operating temperature is 0 to 40 ºC or 32 to 104 
ºF).
