Eco 1 .	. Lowers brightness and decrease of fan
	speed. Lower brightness reduces the
	lamp power consumption and extends
	the lamp life.
Eco 2 .	. Lowers brightness and increase of fan
	speed. Lower brightness reduces the
	lamp power consumption and extends
	the lamp life. It is recommended to
	use Eco 2 when using the projector
	continuously over a long period of time.
	The fan noise becomes louder in Eco 2
	than in Eco 1. Select the suitable mode
	for the used environment.
