To turn off the projector power
1. Press the   Power button on the remote control or 
the  Power button on the control panel to turn off the 
projector lamp.
An on-screen message appears asking if you’re sure you want 
to turn off the power.
2. Press the Power button again to turn off the power.
When you press the Power button a second time, the 
Lamp LED indicator flashes green. This indicates that the lamp 
has turned off, but the fan is still running to cool the lamp.
3. Do NOT turn off the power or unplug the power cable before 
the Lamp LED turns off. 
The fan must continue to run to cool the lamp. This protects the 
lamp from overheating and possible damage.
4. Do not turn on the projector again for at least five minutes. 
Faster on/off cycles will damage the lamp and reduce lamp life.
5. After about two minutes, disconnect the power cord. NOTE:If you don’t press the button within a few seconds, the 
message disappears and the lamp remains lit. This convenient 
design is in case you accidently press the Power button in the 
middle of a show and do not want to turn off the projector.
