3. Press the P 

Power

 button again. The lamp turns off, and the 

Power

 light flashes orange for about 20 seconds as the projector 

cools down. When the projector has cooled, it beeps twice to 
indicate that power is off. The 

Power

 light stays orange and the 

exhaust fan shuts off.

If you want to turn the projector on again, wait until the orange 
light stops flashing. Then press the P 

Power

 button.

4. Press up on the blue foot release lever and lower the projector to 

retract the front adjustable foot, as shown.

5. Replace the lens cap and unplug the power cord.

6. Turn off and disconnect any equipment plugged into the 

projector.

When the projector has not 
received any input signals for 
30 minutes, it automatically 
turns off the projector lamp 
and enters “sleep mode.” This 
conserves electricity, cools the 
projector, and extends the life 
of the lamp. If you are done 
using the projector, unplug 
the power cord. If you want 
to start projecting again, press 
the P 

Power

To avoid damaging the 
projector or lamp, never 
unplug the power cord 
when the Power light is 
green or flashing orange.
