PROGRAM TIMER
This	option	tur ns 	on/off 	the 	projector 	and 	changes 	video 	signals , 	and 	selects 	ECO 	mode 	automatically 	at 	a 	specified 	time .
NOTE:
•	 Before	using	[PROGRAM	TIMER],	make	sure	that	the	[DATE	AND	TIME]	feature	is	set.	(→ page 161)
•	 Make	sure	that	the	projector	is	in	the	stand	by	condition	with	the	POWER	cord	connected.
•	 The	projector	has 	a 	built-in 	clock. 	The 	clock 	will 	keep 	working 	for 	about 	two 	weeks 	after 	the 	main 	power 	is 	turned 	off. 	If 	the 	main 	
power	is	not	supplied	to	the	projector	for	two	weeks	or	more,	the	built-in	clock	stops	working.
•	 When	[PROGRAM	TIMER]	is	enabled,	the	[STANDBY	MODE]	setting	becomes	invalid.
	 This	means	that	the	projector	is	in	the	same	condition	when	the	[NORMAL]	is	selected	for	[STANDBY	MODE].

❶ Mounting a lens (sold separately)
Optional	bayonet 	style 	lenses 	can 	be 	used 	with 	this 	projector .	The 	descr iptions 	here 	are 	f or 	the 	NP18ZL 	(1.3x 	z oom) 	
lens	on	the	PX750U2.	Mount 	 other 	 lenses 	 in 	 the 	 same 	 manner.
Important:
•	 Be	sure	to	perform	[CALIBRATE]	after	replacement	of	the	lens.	 (→	page	125)
NOTE:
•	 The	projector	and	lenses	are	made	of	precision	parts.	Do	not	subject	them	to	shock	or	excessive	forces.
•	 Remove	the 	separately 	sold 	lens 	when 	moving 	the 	projector . 	If 	not, 	the 	lens 	could 	be 	subject 	to 	shock 	while 	the 	projector 	is 	being 	
moved,	damaging	the	lens	and	the	lens	shift	mechanism.
•	 Turn	off	the 	power 	and 	wait 	for 	the 	cooling 	fan 	to 	stop 	and 	turn 	off 	the 	main 	power 	switch 	before 	mounting 	or 	removing 	the 	lens.
•	 When	dismounting	the 	lens 	from 	the 	projector , 	return 	the 	lens 	position 	to 	the 	home 	position 	before 	turning 	off 	the 	power . 	Failure 	
to	do	so 	may 	prevent 	the 	lens 	from 	being 	mounted 	or 	dismounted 	because 	of 	narrow 	space 	between 	the 	projector 	and 	the 	lens.
•	 Never	touch	the	lens	surface	while	the	projector	is	operating.
•	 Be	very	careful	not	to	let	dirt,	grease,	etc.,	on	the	lens	surface	and	not	to	scratch	the	lens	surface.
•	 Perform	these	operations	on	a	flat	surface	over	a	piece	of	cloth,	etc.,	to	prevent	the	lens	from	getting	scratched.
•	 When	leaving	the 	lens 	off 	the 	projector 	for 	long 	periods 	of 	time, 	mount 	the 	dust 	cap 	on 	the 	projector 	to 	prevent 	dust 	or 	dirt 	from 	
getting inside.
•	 If	you	have	multiple	projectors,	be	careful	of	the	following:
	 The	following	lenses	designed	exclusively	for	this	projector	cannot	mounted	onto	another	projector.
-	 PX750U2:	NP16FL/NP17ZL/NP18ZL/NP19ZL/NP20ZL/NP21ZL/NP31ZL
-	 PX700W2/PX800X2:	NP06FL/NP07ZL/NP08ZL/NP09ZL/NP10ZL/NP31ZL
Mounting the lens
1.	 Remove	the	dust	cap	from	the	projector.
2.	 Remove	the	lens	cap	on	the	back	of	the	lens.
•	 The	lens	NP18ZL	is	used	as	an	example.
3.	 While	pressing	the 	LENS 	b utton 	on 	the 	pr ojector's 	fr ont 	
panel	fully	in,	inser t 	the 	lens 	onto 	the 	pr ojector 	with 	the 	
arrow	mark	in	the	label	on	the	lens	facing	upwards.
	 Insert	the	lens 	slo wly 	all 	the 	w ay 	in, 	k eeping 	the 	positioning 	
slit at the same angle.

4.	 Release	the	LENS	button	and	then,	turn.
 Turn until a click is heard.
 The lens is now fastened onto the projector.
TIP:	Mounting	the	lens	theft	prevention	screw
Fasten	the	lens 	theft 	prevention 	screw 	included 	with 	the 	projector 	to 	
the	bottom	of	the	projector	so	that	the	lens	cannot	be	removed	easily.
Removing the lens
Before removing the lens:
1.	 Turn	on	the	projector	and	display	an	image.	(→ page 17)
2.	 Press	and	hold	the	SHUTTER/HOME	POSITION	button	for	2	seconds.
 The lens position will be moved to the home position.
3.	 Turn	off	the	projector,	turn 	 off 	 the 	 main 	 power 	 switch,	 and 	 then 	 unplug 	 the 	 power 	 cord.	
4.	 Wait	until	the	projector	cabinet	is	cool	enough	to	handle.
1.	 While	pressing	the 	LENS 	b utton 	on 	the 	pr ojector’s 	fr ont 	
panel	fully	in,	turn 	 the 	 lens 	 counterclockwise.
 The lens comes off.
NOTE:	If	the 	lens 	cannot 	be 	removed 	when 	the 	LENS 	button 	is 	pressed, 	
check	whether	the	lens	theft	prevention	screw	is	mounted.
2.	 After	slowly	pulling	t he	l ens	o ff	t he	p rojector,	r elease	t he	
LENS	button.
- After removing the lens, mount the lens caps (front and 
back) included with the lens before storing the lens.
-	 If	no	lens 	is 	going 	to 	be 	mounted 	on 	the 	projector , 	mount 	
the dust cap included with the projector.

Cautions when connecting an HDMI cable
•	 Use	a	certified	High	Speed	HDMI®	Cable	or	High	Speed	HDMI®	Cable	with	Ethernet.
Cautions	when	connecting	a	DisplayPort	cable
•	 Use	a	certified	DisplayPort	cable.
 
•	 Depending	on	the	computer,	some	time	may	be	required	until	the	image	is	displayed.
•	 Some	DisplayPort	cables	(commercially	available)	have	locks.
•	 To	disconnect	the	cable,	press	the	button	on	the	top	of	the	cable’s	connector,	then	pull	the	cable	out.
•	 No	power	is	supplied	from	the	DisplayPort	input	connector	to	the	connected	device.

in	some	cases	the	image	may	not	be	displayed.
•	 When	the	HDMI 	output 	of 	a 	computer 	is 	connected 	to 	the 	Displa yPort 	input 	connector , 	use 	a 	con verter 	(commer-
cially	available).

NOTE:	When	Viewing	a	DVI	Digital	Signal
•	 Use	a	DVI-to-HDMI 	cable 	compliant 	with 	DDWG 	(Digital 	Display 	W orking 	Group) 	DVI 	(Digital 	Visual 	Inter face) 	revision 	1.0 	stan-
dard.	The	cable	should	be	within	197"/5	m	long.
•	 Turn	off	the	projector	and	the	PC	before	connecting	the	DVI-to-HDMI	cable.
•	 To	project	a	DVI	digital	signal:	Connect	the	cables,	turn	the	projector	on,	then	select	the	HDMI	input.	Finally,	turn	on	your	PC.
	 Failure	to	do 	so 	may 	not 	activate 	the 	digital 	output 	of 	the 	graphics 	card 	resulting 	in 	no 	picture 	being 	displayed. 	Should 	this 	happen, 	
restart	your	PC.
