Some devices have a discrete power on and discrete power off codes in the database or elseware. If your activity powers up the projector every time you enter it, use a discrete power on code . It will only turn the power on once this way, no matter how many times you enter the activity.
If there is a wait screen (animation) on the remote , just disable it.
