Power management
Power management enables the projector to automatically turn off if there is no signal received by
any input.
Select from the following:
Off
5 minutes
10 minutes
20 minutes
30 minutes
Screen trigger
Set Screen trigger to On to enable the projector to automatically lower the projection screen when
powering on. When powering off, Screen trigger stops sending a low voltage trigger to the screen
controller and the screen goes up.
Fan control
Fan control is used to set the speed of the internal cooling fan. Set Fan Speed to Max in altitudes
over 1500 meters (5000 feet).
The Fan control option default is Normal, which enables the projector to automatically detect fan re-
quirements. For higher temperature locations or prolonged use, the Max option is available to provide
greater cooling capacity.
