Important Information
Fire and Shock Precautions
•   Ensure  that  there  is  sufficient  ventilation  and  that  vents  are  unobstructed  to  prevent  the  build-up  of  heat  inside 
your projector. Allow at least 4 inches (10cm) of space between your p\
rojector and a wall.
•
 
Do not try to touch the ventilation outlet as it can become heated while\
 the projector is turned on.
•
 
Prevent  foreign  objects  such  as  paper  clips  and  bits  of  paper  from  falling  into  your  projector.  Do  not  attempt  to 
retrieve  any  objects  that  might  fall  into  your  projector.  Do  not  insert  any  metal  objects  such  as  a  wire  or  screw-
driver into your project. If something should fall into your projector, disconnect it immediately and have the object 
removed by a qualified service personnel.
•
 
Do not place any objects on top of the projector.
•
 
Do not touch the power plug during a thunderstorm. Doing so can cause el\
ectrical shock or fire.
•
 
The projector is designed to operate on a power supply of 100-240V AC 50/60 Hz. Ensure that your power supply 
fits this requirement before attempting to use your projector.
•
 
Do not look into the lens while the projector is on. Serious damage to y\
our eyes could result.
•
 
Keep any items such as magnifying glass out of the light path of the projector. The light being projected from the 
lens is extensive, therefore any kind of abnormal objects that can redirect light coming out of the lens, can cause 
unpredictable outcome such as fire or injury to the eyes.
•
 
Do not cover the lens with the black lens cap or equivalent while the projector is on. Doing so can lead to melting 
of the cap and possibly burning your hands due to the heat emitted from \
the light output.
•
 
Do  not  place  any  objects,  which  are  easily  affected  by  heat,  in  front  of  the  projector  lens  or  a  projector  exhaust 
vent.
 
Doing so could lead to the object melting or getting your hands burned from the heat that is emitted from the light 
output and exhaust.
•
 
Handle the power cable carefully. A damaged or frayed power cable can ca\
use electric shock or fire.
-
  Do not use any power cables than the supplied one.   
-
  Do not bend or tug the power cable excessively.
-
  Do not place the power cable under the projector, or any heavy object.
-
  Do not cover the power cable with other soft materials such as rugs.
-
  Do not heat the power cable.
-
  Do not handle the power plug with wet hands.
•
 
Turn  off  the  projector,  unplug  the  power  cable  and  have  the  projector  serviced  by  a  qualified  service  personnel 
under the following conditions:
-   When the power cable or plug is damaged or frayed.
-
  If liquid has been spilled into the projector, or if it has been exposed\
 to rain or water. 
-
  If the projector does not operate normally when you follow the instructi\
ons described in this user’s manual.
-
  If the projector has been dropped or the cabinet has been damaged.
-
  If the projector exhibits a distinct change in performance, indicating a\
 need for service.
•
 
Disconnect the power cable and any other cables before carrying the proj\
ector
•
 
Turn off the projector and unplug the power cable before cleaning the ca\
binet or replacing the lamp.
•
 
Turn off the projector and unplug the power cable if the projector is no\
t to be used for an extended period of time.
•
 
When using a LAN cable:
 
For safety, do not connect to the connector for peripheral device wiring\
 that might have excessive voltage.

Lamp Replacement
•  To replace the lamp, follow all instructions provided on page 117.
•
 
Be sure to replace the lamp when the message 
[ Th E   LA mp h AS   REAC h ED   T h E   END   OF   ITS   USA b LE   LIFE .

of its usable life, the lamp bulb may shatter, and pieces of glass may be scattered in the lamp case. Do not touch 
them as the pieces of glass may cause injury.
 
If this happens, contact your dealer for lamp replacement.
A Lamp Character  st  c
The projector has a high-pressure mercury lamp as a light source.
A lamp has a characteristic that its brightness gradually decreases with age. Also repeatedly turning the lamp on 
and off will increase the possibility of its lower brightness.
CAUTION:
When removing the lamp from a ceiling-mounted projector, make sure that no one is under the projector. Glass 
fragments could fall if the lamp has been burned out.
Important Information
Remote Control Precautions
•  Handle the remote control carefully.
•   If the remote control gets wet, wipe it dry immediately.
•
  Avoid excessive heat and humidity.
•
  Do not heat, take apart, or throw batteries into fire.
•
  If you will not be using the remote control for a long time, remove the \
batteries.
•
  Ensure that you have the batteries’ polarity (+/–) aligned corre\
ctly.
•
  Do not use new and old batteries together, or use different types of bat\
teries together.
•
  Dispose of used batteries according to your local regulations.
CAUTION
•  Do  not  use  the  tilt-foot  for  purposes  other  than  originally  intended.  Misuses  such  as  using  the  tilt  foot  to  carry 
or hang (from the wall or ceiling) the projector can cause damage to t\
he projector.
•
 
Do not send the projector in a soft case by parcel delivery service or cargo shipment. The projector inside the 
soft case could be damaged.
•
 
Select  [ H
IGH
]  in  Fan  mode  if  you  continue  to  use  the  projector  for  consecutive  days.  (From  the  menu,  select 
[S ETUP  - O PTIONS] → [F AN  M ODE] → [H IGH].)
•
 
Do  not  unplug  the  power  cable  from  the  wall  outlet  or  projector  when  the  projector  is  powered  on.  Doing  so 
can cause damage to the AC IN connector of the projector and (or) the \
prong plug of the power cable.
 
To  turn  off  the  AC  power  supply  when  the  projector  is  powered  on,  use  a  power  strip  equipped  with  a  switch 
and a breaker.
•
 
The projector can be unplugged during its cool down period after it is t\
urned off. 
 
Do  not  try  to  touch  the  ventilation  outlet  on  the  left  front  (when  seen  from  the  front)  as  it  can  become  heated 
while the projector is turned on and immediately after the projector is \
turned off.
•
 
Do  not  turn  off  the  AC  power  for  60  seconds  after  the  lamp  is  turned  on  and  while  the  POWER  indicator  is 
blinking green. Doing so could cause premature lamp failure.
