When the projector has cooled down, the operation indicator
stops flashing and remains orange.
Note: If you press the Power button to turn the projector back on
while the operation indicator is orange, there may be a delay
before a projected image appears.
Note: Do not project the same static image for extended time.
Doing so may print the image and cause the afterimage on the
panel.

Sleep Mode

Sleep mode conserves electricity by automatically turning off
the lamp after the projector has not been used for 30 minutes.
In sleep mode, the projector's operation indicator is orange
and only a minimum amount of the projector's circuitry
remains on. This conserves electricity, cools the projector, and
extends the life of the lamp. When the projector is in sleep
mode, you can press the Power button to resume projecting
images, or you can unplug the projector's power cord to turn
it off.
Note: When you don't use the projector, turn off the power
switch on the projector. The orange operation indicator turns off.
