ODE
After projection or when a warning occurred (cases 7-16), the unit will go through a 1 minute cool-down process
known as the Cool Down mode. This function is to prevent lamp breakage and shortened lamp life but also damage
to the internal components of the projector.
The Cool Down mode is indicated by the blinking red STANDBY/ON led. When in Cool Down mode, the projector
cannot be turned ON.
After the Cool Down process is completed, the unit will automatically switch to the Standby mode indicated by a red
STANDBY/ON led.
C
AUTION
When in Cool Down mode, do not pull out the plug from the outlet. Also, do not block the air inlets/exhaust vents by
standing the projector on its end or laying it on its side.
