Remote control
This projector provides two different remote control codes; 
the factory-set, initial code (Code 1) and the secondary code 
(Code 2). This switching function prevents remote control 
interference when several projectors or video equipment

When the projector is operated in “Code 2,” both the 
projector and the remote control must be switched to 
“Code 2.”
 
To change the code for the projector:
Select either “Code 1” or “Code 2” in this Setting Menu.
To change the code for the remote control:
Press and hold both the MENU and IMAGE buttons 
together for more than 5 seconds. After changing the code,

code on the projector.
•  if the batteries are removed from the remote control for a 
long period of time, the remote control code will be reset.

The WARNING indicator shows the state of the function which protects the projector. Check the state of the 
WARNING indicator and the POWER indicator to take proper maintenance. Indicators
Warning Indicator
The projector is shut down and the WARNING 
TEMP. indicator is blinking red.
When the temperature inside the projector reaches a 
certain level, the projector is automatically shut down to 
avoid overheating. The POWER indicator is blinking while 
the projector is being cooled down. When the projector has 
cooled down enough (to its normal operating temperature), 
it can be turned on again by pressing the ON/STAND-BY 
button.  
✔Note:
• The WARNING TEMP. indicator continues to blink even 
after the temperature inside the projector returns to 
normal. When the projector is turned on again, the 
WARNING TEMP. indicator stops blinking. 
Then check the matters below:
–     Did you provide appropriate space for the projector to 
be ventilated? Check the installing condition to see if 
ventilation slots are not blocked.
–     Has the projector been installed near an Air-Conditioning/
Heating Duct or Vent? Move the installation of the 
projector away from the duct or vent.
–     Are the air filters clean? Clean the air filters periodically. 
(p.56) 
Indicators

The air filter prevents dust from accumulating on the surface of the optical elements inside the projector. Should 
the air filter become clogged with dust particles, it will reduce coolin\
g fans’ effectiveness and may result in a 
buildup of internal heat and adversely affects the life of the projector. Clean the air filter by following the steps 
below.
Gently clean the filter by using a brush or blower.
3
Reinstall the filter into the projector properly.
4
CAUTION
Do not operate the projector with the air filter 
removed. Dust may accumulate on the optical 
elements degrading picture quality. Do not put 
anything into the air intake vents. Other wise it may 
result in malfunction of the projector.
RECOMMENDATION We recommend avoiding dusty/smoky environments when you operate the projector. Usage in these 
environments may cause poor image quality.
When you use the projector under dusty or smoky conditions, dust may accumulate on the lens, LCD panels, or 
optical elements inside the projector degrading the quality of a projected image.
When the symptoms above are noticed, contact your authorized dealer or service station for proper cleaning.
✔Note:
• When  cleaning  the  air  filter,  protect  the 
infrared  remote  receiver  with  a  soft  cloth  to 
avoid damaging it.
•   If  the  filter  is  heavily  clogged  and  unable  to 
clean,  replace  it  with  a  new  one.  Consult 
your dealer for details.

This projector uses a high-pressure lamp which must be handled carefully and properly. Improper handling 
may result in accidents, injury, or create a fire hazard.
●  Lamp life may differ from lamp to lamp and according to the environment of use. There is no guarantee 
of  the  same  life  for  each  lamp.  Some  lamps  may  fail  or  terminate  their  life  in  a  shorter  period  of  time 
than other similar lamps.
●
 If  the  projector  indicates  that  the  lamp  should  be  replaced,  i.e.,  if  the  LAMP  REPLACE  indicator  lights 
up, replace the lamp with a new one IMMEDIATELY after the projector has cooled down. 
　  (Follow  carefully  the  instructions  in  the  Lamp  Replacement  section  of  this  manual.)  Continuous  use  of 
the lamp with the LAMP REPLACE indicator lighted may increase the risk of lamp explosion.  
●
 A  Lamp  may  explode  as  a  result  of  vibration,  shock,  or  degradation  as  a  result  of  hours  of  use,  as  it 
comes  to  the  end  of  life.  Risk  of  explosion  may  differ  according  to  the  environment  or  conditions  in 
which the projector and lamp are being used.
IF A LAMP EXPLODES, THE FOLLOWING SAFET y PRECAUTIONS SHOULD BE TAKEN.
If  a  lamp  explodes,  disconnect  the  projector’s  AC  plug  from  the  AC  outlet  immediately.  Contact  an 
authorized  service  station  for  a  checkup  of  the  unit  and  replacement  of  the  lamp.  Additionally,  check 
carefully to ensure that there are no broken shards or pieces of glass around the projector or coming out 
from  the  cooling  air  circulation  holes.  Any  broken  shards  found  should  be  cleaned  up  carefully.  No  one 
should  check  the  inside  of  the  projector  except  those  who  are  authorized  trained  technicians  and  who 
are familiar with projector service. Inappropriate attempts to service the unit by anyone, especially those 
who are not appropriately trained to do so, may result in an accident or injury caused by pieces of broken 
glass.
