When replacing the lamp because it has stopped 
illuminating, there is a possibility that the lamp maybe 
broken. If replacing the lamp of a projector which has 
been installed on the ceiling, you should always assume 
that the lamp is broken, and you should stand to the side 
of the lamp cover, not underneath it. Remove the lamp 
cover gently. Small pieces of glass may fall out when 
the lamp cover is opened. If pieces of glass get into your 
eyes or mouth, seek medical advice immediately.

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.
l 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.
l  If  the  projector  indicates  that  the  lamp  should  be  replaced,  i.e.,  if  the  LAMP  1/2  REPLACE  indicators 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 1/2 REPLACE indicators lighted may increase the risk of lamp explosion.  
l  A  Lamp  may  explode  as  a  result  of  vibration,  shock  or  degradation  as  a  result  of  hours  of  use  as  its 
lifetime  draws  to  an  end.  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.

							The WARNING indicators show the state of the function which protects the projector. Check the state of the 
WARNING indicators and the POWER indicator to take proper maintenance. 
Warning Indicators
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 will be automatically shut

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 the air 
vents of the projector 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.
–   Is the filter clean? Clean the filter periodically or replace it 
with a new one.
The projector is shut down and the WARNING TEMP. 
indicator lights red.
When the projector detects an abnormal condition, it will 
be automatically shut down to protect the inside of the 
projector and the WARNING TEMP. indicator lights red.  In 
this case, unplug the AC power cord and plug it, and then 
turn on the projector once again to verify operation. If the 
projector cannot be turned on and the WARNING TEMP.
