    4.	 Tighten	the	two	screws	on	both	sides	of	the	slot.
    •	 Be	sure	to	tighten	the	screws.
    	 This	will	complete	installation	of	the	optional	board.
    	 To	select	the	optional	board	source,	select	SLOT	as	the	input.
    NOTE:
    •	 Mounting	the	optional 	board 	may 	cause 	the 	fans 	to 	run 	in 	the 	standby 	mode 	for 	the 	purpose 	of 	cooling 	depending 	on 	the 	optional 	
    board.	The	fan 	speed 	may 	also 	increase 	in 	order 	to 	cool 	the 	projector 	properly . 	Both 	of 	these 	instances 	are 	considered 	normal 	
    and not a malfunction of the projector.
