 Replacing the Filters
There	are	two	filters,	one	located	at	the	front	of	the	projector	and	one	on	the	side.
Optional	filters	(two	filter)	are	available.
Small	one	for	the	front
Large	one	for	the	left	side
NOTE:
•	 Replace	both	filters	with	the	new	ones	at	the	same	time.
•	 Before	replacing	 the	filters,	 use	a	vacuum	 cleaner	to	vacuum	 dust	and	dirt	from	 the	vents	 (inlet)	 of	the	 projector	 and	use	a	dry	
soft cloth to wipe dust off the cabinet.
•	 The	projector	contains	high-precision	parts.	Keep	out	dust	and	dirt	during	filter	replacement.
•	 Do	not	wash	the	filter	with	water.	Water	will	damage	the	filter	membrane.
•	 Attach	 the	filter	 in	the	 correct	 orientation.	 Failure	to	do	 so	may	 cause	 dust	and	dirt	to	enter	 inside	 the	projector,	 resulting	in	projec-
tor malfunction.
