This	 DLP™ 	 projector 	 is 	 one 	 of 	 the 	 very 	 best 	 projectors 	 available 	 today. 	 The 	 projector 	 enables 	 you 	 to 	 project 	 pre-
cise
	
images
	
up
	
to
	
300
	
inches
	
(measured
	
diagonally)
	
from
	
your
	
PC
	
or
	
Macintosh
	
computer
	
(desktop
	
or
	
notebook), 	
VCR,
	
DVD

camera.
You
	
can
	
use
	
the
	
projector
	
on
	
a
	
tabletop
	
or
	
cart,
	
you
	
can
	
use
	
the
	
projector
	
to
	
project
	
images
	
from
	
behind
	
the 	
screen,
	
and
	
the
	
projector
	
can
	
be
	
permanently
	
mounted
	
on
	
a
	
ceiling*

*1	 Do	 not 	 attempt 	 to 	 mount 	 the 	 projector 	 on 	 a 	 ceiling 	 yourself.
	 The 	 projector 	 must 	 be 	 installed 	 by 	 qualified 	 technicians 	 in 	 order 	 to 	 ensure 	 proper 	 operation 	 and 	 reduce 	 the 	
risk 	 of 	 bodily 	 injury.
	 In
	 addition, 	 the 	 ceiling 	 must 	 be 	 strong 	 enough 	 to 	 support 	 the 	 projector 	 and 	 the 	 installation 	 must 	 be 	 in 	 accor

Features you'll enjoy:
•	 AUTO 	 FOCUS 	 function 	
	 When
	 you 	 turn 	 on 	 the 	 power, 	 change 	 the 	 zoom 	 or 	 reposition 	 the 	 projector, 	 the 	 AUTO 	 FOCUS 	 function 	 will 	 work 	
instantly.
	 The 	 focus 	 sensor 	 on 	 the 	 projector 	 detects 	 the 	 distance 	 to 	 the 	 screen 	 and 	 automatically 	 adjusts 	 the 	 focus 	 of 	 an 	
image 	 as 	 well 	 as 	 reducing 	 the 	 required 	 set-up 	 time.
•	 Auto
	 vertical 	 keystone 	 correction

when 	 projecting 	 an 	 image) 	 using 	 a 	 power 	 strip 	 equipped 	 with 	 a 	 switch 	 and 	 a 	 breaker.
	 The
	 AUTO 	 POWER 	 ON(AC) 	 and 	 AUTO 	 POWER 	 ON(COMP.) 	 features 	 eliminates 	 the 	 need 	 to 	 always 	 use 	 the 	
POWER 	 button 	 on 	 the 	 remote 	 control 	 or 	 projector 	 cabinet.

	 Connecting
	
the
	
optional
	
Bluetooth® 	 USB 	 adaptor 	 (NP01BA) 	 to 	 the 	 projector 	 will 	 allow 	 you 	 to 	 transmit 	 images

•	 The 	 infrared 	 signal 	 operates 	 by 	 line-of-sight 	 up 	 to 	 a 	 distance 	 of 	 about 	 22 	 feet/7 	 m 	 and 	 within 	 a 	 60-degree 	 angle 	
of 	 the 	 remote 	 sensor 	 on 	 the 	 projector 	 cabinet.
•	 The

2. Installation and Connections
➊ Setting Up the Screen and the Projector
Select ng a Locat  on
The	 further 	 your 	 projector 	 is 	 from 	 the 	 screen 	 or 	 wall, 	 the 	 larger 	 the 	 image. 	 The 	 minimum 	 size 	 the 	 image 	 can 	 be 	 is 	
33" 	 (0.84 	 m) 	 measured 	 diagonally 	 when 	 the 	 projector 	 is 	 roughly 	 57 	 inches 	 (1.44 	 m) 	 from 	 the 	 wall 	 or 	 screen. 	 The 	
largest 	 the 	 image 	 can 	 be 	 is 	 300" 	 (7.6 	 m) 	 when 	 the 	 projector 	 is 	 about 	 484 	 inches 	 (12.3 	 m) 	 from 	 the 	 wall 	 or 	 screen. 	
Use 	 the 	 chart 	 below 	 as 	 a 	 rough 	 guide.
Your	 projector 	 is 	 simple 	 to 	 set 	 up 	 and 	 use. 	
But 	 before 	 you 	 get 	 started, 	 you 	 must 	 first:
➊	Set	 up 	 a 	 screen 	 and 	 the 	 projector.
➋	C o n n e c t	 y o u r 	 c o m p u t e r 	 o r 	 v i d e o

 WARNING
*	 Installing	 your 	 projector 	 on 	 the 	 ceiling 	 must 	 be 	 done 	
by 	 a 	 qualified 	 technician. 	 Contact 	 your 	 NEC 	 dealer 	
for 	 more 	 information.
*	 Do
	 not 	 attempt 	 to 	 install 	 the 	 projector 	 yourself.
•	 Only
	 use 	 your 	 projector 	 on 	 a 	 solid, 	 level 	 surface. 	 If 	
the 	 projector 	 falls 	 to 	 the 	 ground, 	 you 	 can 	 be 	 injured 	
and 	 the 	 projector 	 severely 	 damaged.
•	 Do
	 not 	 use 	 the 	 projector 	 where 	 temperatures 	 vary 	
greatly. 	 The 	 projector 	 must 	 be 	 used 	 at 	 temperatures 	
between 	 41˚F 	 (5˚C) 	 and 	 104˚F 	 (40˚C). 	 ([ECO] 	 mode 	
selected 	 automatically 	 at 	 95°F 	 to 	 104°F/35°C 	 to 	 40°C. 	
Note 	 that 	 [ECO] 	 mode 	 will 	 be 	 selected 	 automatically 	
at 	 86°F 	 to 	 104°F/30°C 	 to 	 40°C 	 when 	 used 	 in 	 [HIGH 	
ALTITUDE].)
•	 Do 	 not 	 expose 	 the 	 projector 	 to 	 moisture, 	 dust, 	 or 	
smoke. 	 This 	 will 	 harm 	 the 	 screen 	 image.
•	 Ensure
	 that 	 you 	 have 	 adequate 	 ventilation 	 around 	
your 	 projector 	 so 	 heat 	 can 	 dissipate. 	 Do 	 not 	 cover 	
the 	 vents 	 on 	 the 	 side 	 or 	 the 	 front 	 of 	 the 	 projector.
