Note:  Cool Down Mode 
After	projection,	the	hot	lamp	goes	through	a	
60-second	cool-down	process	known	as	‘cool	
down	mode’.	This	mode	is	designed	to	prevent	
damage	and	deformation	that	heat	from	the	
heated	lamp	may	cause	to	the	internal	com-
ponents	of	the	projector.	It	also	minimises	the	
chance	of	lamp	breakage	and	shortened	lamp	
life.	
The	cool	down	mode	is	indicated	by	the	blink-
ing	Standby	indicator.	When	in	the	cool	down	
mode,	the	OPERATE ON	button	is	disabled.	
After	the	cool	down	process	is	completed,	
the	unit	will	automatically	switch	into	standby	
mode.	
CAUTION: 
When	in	the	cool-down	mode,	do	not	pull	out	
the	plug	from	the	power	socket.	Also,	do	not	
block	the	air	inlets/	exhaust	vents	by	standing	
this	unit	on	its	end	or	laying	it	on	its	side.	
Lamp replacement
The	timing	and	procedure	for	lamp	replace-
ment	is	discussed	on	page	27	et seq.
Indicator Display Table
The	projector	employs	different	patterns	of	indicator	illumination	to	indicate	its	various	operational

Remote Control
The	Meridian/Faroudja	infra-red	remote	control	
is	used	to	operate	both	DILA	projectors	and	
digital	video	processors	(DVP)	made	by	Merid-
ian.	As	a	result,	the	remote	control	unit’s	but-
tons	often	have	a	dual	function.	
To operate the appropriate device, press its Se-
lect button (labelled A on the diagram below) 
before attempting to control the unit.	
The	IR	transmitting	diode	is	located	at	the	top	
of	the	remote	control:	point	it	towards	one	of	
the	IR	sensors	at	the	front	or	rear	of	the	pro-
jector.	In	addition,	you	may	be	able	to	control	
the	projector	by	reflecting	the	infrared	beam	
from	the	screen	so	that	it	hits	the	projector’s	
front	sensor.

How	effective	this	method	of	operation	is	will	
depend	on	your	screen	and	its	reflectivity	to	
infrared.	The	sensors	on	the	projector	have	an	
acceptance	angle	of	about	30	degrees	either	
side	of	a	centre	line	running	through	the	unit	
from	front	to	back.	Outside	this	angle,	opera-
tion	of	the	remote	control	will	be	less	reliable.	
In	the	case	of	using	screen	reflection,	remem-
ber	that	IR	rays	travel	in	straight	lines,	and	that	
rays	reaching	the	screen	from	the	remote	will	
be	reflected	at	the	same	angle;	the	reflected	
rays	need	to	arrive	at	the	projector	within	the	
+/-	30	degree	angle	described	above.	Imagine	
where	on	the	screen	you	would	have	to	throw	
a	ball	to	bounce	off	and	hit	the	projector	–	just	
don’t	try	it	for	real.	The	maximum	direct	path	
length	for	the	remote	is	about	7metres.

Considerations for projector 
installation
Please	read	the	following	carefully	before	in-
stalling	this	unit.	
Installation Environment 
This	unit	is	a	precision	device.	Do	not	install	it	
in	the	following	places.	Doing	so	may	cause	
fire	or	malfunction	of	the	unit.
•	 Where	there	is	water,	humidity	or	dust
•	 Where	the	unit	may	be	subjected	to	oily	or	ciga-
rette	smoke
•	 On	a	soft	surface	such	as	carpet	or	cushion
•	 Where	the	unit	may	be	subjected	to	high	tem-
perature	due	to	direct	sunlight
•	 When	temperature	is	high	or	low.	
	 Allowable	operation	temperature	range:	+5	to	
+35	degrees	Celsius.	
	 Allowable	relative	humidity	range:	20	%	to	80	
%	(no	condensation)	
	 Allowable	storage	temperature	range:	-10	to	
+60	degrees	Celsius
•	 Any	room	in	which	there	is	cigarette	smoke	or	
grease.	
	Even where smoke and grease levels are mini-
mal, prolonged exposure will affect this unit. 
This unit produces significant amounts of 
heat, and the optical components are cooled 
by taking in a large amount of air. The optical 
path may be soiled by grease/dirt, thus causing 
images to become dark or colour projection to 
deteriorate. Where	soiling	of	the	optical	compo-
nents	occurs,	total	removal	of	grease/dirt	may	
not	be	possible.
Operating Precautions
This	unit	uses	a	light	source	that	reaches	high	
temperatures	during	projection.
Do not allow projection under the follow-
ing conditions, as doing so may cause fire 
or failure of the unit:
•	 Projection	with	the	unit	laid	on	its	sides
•	 Projection	with	the	unit	installed	in	an	unrea-
sonable	angle
	Avoid using this unit at an angle of more than  
 degrees horizontally and 2 degrees vertically. 
Doing so may cause unevenness in the colour 
and/or shorten the lamp life.
•	 Projection	in	a	location	that	blocks	the	air	inlets	
or	exhaust	vents
•	 Projection	in	a	place	exposed	to	air	blasts	from	
an	air	conditioner
•	 Projection	without	removing	the	lens	cap
Mounting the projector
The	projector	can	be	operated	in	a	free-stand-
ing	position	using	the	feet	supplied.	To	mount	
the	projector,	remove	the	4	feet	and	make	use	
of	the	4	screw	holes	(M8	nuts)	on	the	under-
side	of	the	projector.	Allow	sufficient	space	
around	the	air	inlets	to	avoid	blocking	them.
Precautions for Ceiling-mount
•	 To	ceiling-mount	this	unit,	special	expertise	and	
techniques	are	necessary.	Be	sure	to	ask	your	
dealer	(or	a	specialist)	to	perform	mounting	(to	
ceilings,	etc.).
•	 Do	not	mount	in	places	that	may	be	subjected	
to	vibration	and	shock.
•	 The	depth	of	the	threaded	holes	is	30	mm.	Use	
screws	shorter	than	30	mm	but	longer	than	19	
mm.	Longer	screws	may	damage	internal	parts	
of	the	projector	and	cause	malfunction.
•	 Safety	of	the	installation	location	should	be	
considered	in	case	this	unit,	or	a	part	of	it,	falls.	
Note	that	if	the	light-source	lamp	is	broken,	
glass	shards	from	the	filter	mesh	may	spread	
outside	the	projector.
Minimum Space Required
Do	not	use	a	cover	which	may	enclose	this	unit	
or	block	the	air	inlets/exhaust	vents.	Allow	suf-
ficient	space	around	this	unit.	When	this	unit	is	
enclosed	in	a	space	of	dimensions	as	indicated	
on	the	left,	use	an	air-conditioner	so	that	inter-
nal	and	external	temperatures	are	the	same.

Projector and Screen Installation
The	optimum	image	can	be	obtained	when	the	centre	of	the	projector’s	lens	and	the	screen	are	
placed	perpendicular	to	each	other.	Take	note	of	the	projection	angle	when	placing	both	items.	
Failing	to	do	so	may	give	rise	to	trapezoidal	distortion	of	the	projected	image.	
•	 Note:	this	unit	does	not	come	with	a	function	to	correct	trapezoidal	distortion	or	adjust	horizontal	
gradient.

Screen Size and Projection Distance
Adjust	the	distance	from	the	lens	to	the	screen	to	achieve	your	desired	screen	size.	
You	will	need	to	have	specified	the	Normal	Throw	(DILA1080MF1)	or	Short	Throw	(DILA1080MF1S)	
version	of	this	projector	when	ordering.	The	Normal	Throw	version	uses	a	1.9x	power	zoom	lens,	
while	the	Short	Throw	version	has	a	1.4x	power	zoom	lens.	As	a	result,	the	Normal	Throw	version	
displays	a	given	image	size	on	a	screen	up	to	about	150%	as	far	away	as	the	same-sized	image	
displayed	by	the	Short	Throw	version.	In	most	cases,	especially	when	the	projector	is	mounted	in	a	
projection	room,	the	Normal	Throw	version	will	be	most	appropriate.	When	the	projectror	is	used	in	
a	smaller	room,	however,	the	Short	Throw	version	will	probably	be	more	effective.	The	relationship	
of	projection	distance	and	screen	size	for	both	versions	is	given	by	the	table	below.
Projection Distance and Projection Screen Size Relationship Chart
•	 The	projection	screen	sizes	(recommended)	and	projection	distances	in	the	table	below	are	provided	only	
as	a	guide.	Please	use	them	as	reference	during	installation.	The	projected	image	size	may	vary	depending	
on	the	manufacturing	tolerance	of	the	lens.	
•	 Use	a	projection	image	of	16:9	aspect	ratio	for	setup	adjustment.

Lens Shift Setting
This	unit	comes	with	a	Lens	Shift	feature	that	
enables	upward/downward	adjustment	of	the	
projection	screen	position.	Adjust	accordingly	
depending	on	the	installation	conditions.	
•	 The	shift	level	is	between	0	%	and	60	%.	The	
shift	level	is	set	to	50	%	as	the	default.	
•	 The	position	of	the	projection	screen	may	be	
out	of	alignment	due	to	the	gear	movement.	
•	 When	lens	shift	setting	(adjustment)	is	complet-
ed,	mount	the	lens	shift	cover	to	this	unit.	
Project a reference image on the screen 
Remove the lens shift cover from the pro-
jector 
•	 Unscrew	the	knurled	aluminium	cover	on	the	
top	of	the	projector.	Note:	Some	units	may	have	
a	smaller	cover	accessed	via	a	hole	in	the	top	
cover	(see	illustration).	Remove	this	with	a	flat-
blade	screwdriver.
Adjust the projection screen position 
•	 Turn	the	shift	adjustment	screw	using	a	flat-
blade	screwdriver	and	adjust	accordingly.	
	 Turn	clockwise	:	Screen	shifts	upwards.	
	 Turn	anti-clockwise	:	Screen	shifts	downwards.

Connecting to Devices 
Before	connection,	be	sure	to	turn	off	both	the	projector	and	the	device	to	be	connected.	
•	 Thoroughly	read	the	manual	that	is	supplied	with	the	device	to	be	connected.	
Connecting a Video Processor
•	 A	Meridian/Faroudja	Digital	Video	processor	is	the	ideal	companion	for	your	projector.	It	is	capable	of	
processing	and	upscaling	all	your	video	sources	to	HD	quality	and	will	give	you	the	maximum	image	qual-
ity	from	any	source.	Consult	your	dealer	for	additional	information.
•	 Video	is	connected	 to	the	 projector	 via	a	DVI	 connector.	 To	avoid	 image	 degradation,	 always	use	the	high-
est	quality	DVI	cables	you	can.	In	addition,	using	HDMI/DVI	adaptor	cables,	you	can	connect	a	Meridian	
HDMAX	121	HDMI	Extender	near	the	projector	end	of	the	run,	which	is	especially	useful	in	the	case	of	
long	cable	runs.		In	any	event,	when	using	a	DVI-D	cable	longer	than	5	m,	the	use	of	a	booster	or	optical	
fiber	cable	is	recommended.	
•	 This	projector	accepts	1080/50p	and	1080/60p	signals	via	the	DVI-D	connector,	and	HDCP	content	pro-
tection	is	supported.
