➌ Replacing the Lamp and the Cooling Pump
After	 your 	 lamp 	 has 	 been 	 operating 	 for 	 2500 	 hours 	 (up 	 to 	 3500 	 hours 	 in 	 ECO 	 mode) 	 or 	 longer, 	 the 	 LAMP 	 indica-
tor
	
in
	
the
	
cabinet
	
will
	
blink
	
red
	
and
	
the
	
message
 [THE LAMP HAS REACHED THE END OF ITS USABLE LIFE. 
PLEASE REPLACE THE LAMP.] 	 will 	 appear. 	 Even 	 though 	 the 	 lamp 	 may 	 still 	 be 	 working, 	 replace 	 it 	 at 	 2500 	 (up 	 to 	
3500 	 hours 	 in 	 ECO 	 mode) 	 hours 	 to 	 maintain 	 optimal 	 projector 	 performance. 	 After 	 replacing 	 the 	 lamp, 	 be 	 sure 	 to 	
clear 	 the 	 lamp 	 hour 	 meter. 	 (

CAUTION
•	 The	 optional 	 lamp 	 comes 	 with 	 the 	 cooling 	 pump.
	 After 	 replacing 	 the 	 lamp, 	 be 	 sure 	 to 	 replace 	 the 	 cooling 	 pump, 	 too.
•	 DO
	 NOT 	 TOUCH 	 THE 	 LAMP 	 immediately 	 after 	 it 	 has 	 been 	 used. 	 It 	 will 	 be 	 extremely 	 hot. 	 Turn 	 the 	 projector 	 off 	
and 	 then 	 disconnect 	 the 	 power 	 cable. 	 Allow 	 at 	 least 	 one 	 hour 	 for 	 the 	 lamp 	 to 	 cool 	 before 	 handling.
•	 DO
	 NOT 	 REMOVE 	 ANY 	 SCREWS 	 except 	 one 	 lamp 	 cover 	 screw 	 and 	 two 	 lamp 	 housing 	 screws. 	 You 	 could 	 re

Note: Remov  ng or Insert  ng the Lamp (St  ck  ng of Pack  ng R  ng)
After	 lamp 	 replacement, 	 a 	 black 	 packing 	 ring 	 may 	 be 	 stuck 	 inside 	 the 	 projector 	 (Fig. 	 A 	 and 	 Fig. 	 B).
If 	 this 	 happens, 	 do 	 the 	 following:
•	 If
	 the 	 used 	 packing 	 ring 	 does 	 not 	 remain 	 inside 	 the 	 projector 	 (Fig. 	 C), 	 proceed 	 with 	 the 	 new 	 lamp 	 housing 	 in
-
stallation.
•	 If 	 the 	 used 	 packing 	 ring 	 is 	 stuck 	 inside 	 the 	 projector 	 (Fig. 	 B), 	 remove 	 it 	 from 	 inside 	 the 	 projector 	 before 	 install
-
ing
	
the
	
new
	
lamp
	
housing.
	
To
	
remove
	
the
	
packing
	
ring,
	
simply
	
pull
	
it
	
off
	
of
	
the
	
stud.
*	 In
	
other
	
cases
	
where
	
the
	
lamp
	
is
	
removed
	
(other
	
than
	
lamp
	
replacement),
	
pulling
	
out
	
the
	
lamp
	
housing
	
may 	
also
	
cause
	
the
	
packing
	
ring
	
to
	
stay
	
stuck
	
inside
	
the
	
projector.
	
If
	
this
	
happens,
	
make
	
sure
	
to
	
insert
	
the
	
lamp 	
housing
	
back
	
in
	
its
	
original
	
position.
 CAUTION
•	 Before 	 removing 	 the 	 used 	 packing 	 ring, 	 be 	 sure 	 to 	 turn 	 off 	 the 	 projector, 	 wait 	 for 	 the 	 cooling 	 fan 	 to 	 stop, 	 dis-
connect
	
the
	
power
	
cable,
	
and
	
allow
	
at
	
least
	
one
	
hour
	
for
	
the
	
lamp
	
to
	
cool.
	 The
	
projector
	
can
	
become
	
very
	
hot
	
when
	
it
	
is
	
turned
	
on
	
and
	
stay

new
	
lamp
	
with
	
the
	
used
	
packing
	
ring
	
stuck
	
inside

requires
	
excessive 	
force
	
to

Condensation  may  form  on  the  lens  if  the  projector  is  cold,  brought  into  a  warm  place  and  is  then  turned  on. 
Should this happen, let the projector stand until there is no condensation on the lens.
Flicker appears on screen •    Set  [FAN  MODE]  to  other  than  [HIGH  ALTITUDE]  mode  when  using  the  projector  at  altitudes  approximately  5000 feet/1500 meters or lower. Using the projector at altitudes less than approximately 5000 feet/1500 meters and setting to [HIGH ALTITUDE] can cause the lamp to overcool, causing the image to flicker.
