lamp with the STATUS indicator blinking (2-cycle On and Off.)
Should this happen, do the following:
•
  Unplug the power cable after the cooling fans stop.
•
  Move the projector to a cooler location if the room where you are presen\
ting is particularly too warm.
•
  Clean the ventilation holes if they are clogged with dust.
•
  Wait about 60 minutes until the inside of the projector becomes cool eno\

Common Problems & Solutions (→ “Power/Status/Lamp Indicator” on page 120)
problemCheck These Items
Does not turn on •   Check that the power cable is plugged in and that the power button on the projector cabinet or the remote control is on. (→ page 19, 20)
•
 
Ensure that the lamp cover is installed correctly. (→ page 119)
•
 
Check to see if the projector has overheated. If there is insufficient ventilation around the projector or if the 
room where you are presenting is particularly warm, move the projector t\
o a cooler location.
•
 
Check to see if you continue to use the projector for another 600 hours after the lamp has reached the end 
of its life. If so, replace the lamp.
 
After replacing the lamp, reset the lamp hours used. (→ page 113)
•
 
The lamp may fail to light. Wait a full minute and then turn on the power again.
• 
 
Set  [FAN  MODE]  to  [HIGH  ALTITUDE]  when  using  the  projector  at  altitudes  approximately  5500  feet/1600 
meters  or  higher.  Using  the  projector  at  altitudes  approximately  5500  feet/1600  meters  or  higher  without setting to [HIGH ALTITUDE] can cause the projector to overheat and the projector could shut down. If this happens, wait a couple minutes and turn on the projector. (→ page 108)
 
Also when the lamp is turned off, the projector internal temperature is hot. If the power is turned on before 
the projector has cooled down, the fan will run a short time before the \
lamp will turn on.
Will turn off •   Ensure that the Auto Power Off, Off Timer is off. (→ page 87, 108)
No picture•   Use the SOURCE button on the projector cabinet or the VIDEO, the S-VIDEO, the COMPUTER 1, the COM-PUTER 2, the HDMI, the VIEWER or the NETWORK button on the remote control to select your source. (→ page 22)
•
 
Ensure your cables are connected properly.
•
 
Use menus to adjust the brightness and contrast. (
→ page 77)
•
 
Check to see if the image is muted. (→ page 31)
•
 
Remove the lens cap.
•

on. Should this happen, let the projector stand until there is no conden\
sation on the lens.
Flicker appears on screen •    Set [FAN MODE] to other than [HIGH ALTITUDE] mode when using the projector at altitudes approximately 5500  feet/1600  meters  or  lower.  Using  the  projector  at  altitudes  less  than  approximately  5500  feet/1600 meters  and  setting  to  [HIGH  ALTITUDE]  can  cause  the  lamp  to  overcool,  causing  the  image  to  flicker. Switch [FAN MODE] to [AUTO]. (→ page 108)
Image is scrolling vertically, horizontally or both•   Use the SOURCE button on the projector cabinet or the VIDEO, the S-VIDEO, the COMPUTER 1, the COM
-PUTER 2, the HDMI, the VIEWER or the NETWORK button on the remote control to select your source (Video, S-Video, Computer, Component, Viewer or NETWORK). (→ page 22)

8. Appendix
If there   s no p  cture, or the p  cture   s not d  splayed correctly.
•  Power on process for the projector and the PC.
 
Be sure to connect the projector and notebook PC while the projector is in standby mode and before turning on 
the power to the notebook PC.
In most cases the output signal from the notebook PC is not turned on unless connected to the projector before 
being powered up.
NOTE: You can check the horizontal frequency of the current signal in the projector’s menu [SOURCE(2)] under Information.  
If it reads “0kHz”, this means there is no signal being output fro\
m the computer. See page 111 or go to next step.
•
 
Enabling the computer’s external display.
 
Displaying  an  image  on  the  notebook  PC’s  screen  does  not  necessarily  mean  it  outputs  a  signal  to  the  projec
-
tor.  When using a PC compatible laptop, a combination of function keys \
will enable/disable the external display.  
Usually, the combination of the ‘Fn” key along with one of the 12 function keys gets the external display to come 
on  or  off.    For  example,  NEC  laptops  use  Fn  +  F3,  while  Dell  laptops  use  Fn  +  F8  key  combinations  to  toggle 
through external display selections.
•
 
Non-standard signal output from the computer
 
If  the  output  signal  from  a  notebook  PC  is  not  an  industry  standard,  the  projected  image  may  not  be  displayed 
correctly.  Should  this  happen,  deactivate  the  notebook  PC’s  LCD  screen  when  the  projector  display  is  in  use. 
Each notebook PC has a different way of deactivate/reactivate the local LCD screens as described in the previ-
ous step. Refer to your computer’s documentation for detailed informa\
tion.
•
 
Image displayed is incorrect when using a Macintosh
 
When using a Macintosh with the projector, set the DIP switch of the Mac adapter (not supplied with the projec
-
tor) according to your resolution. After setting, restart your Macintos\
h for the changes to take affect.
 
For  setting  display  modes  other  than  those  supported  by  your  Macintosh  and  the  projector,  changing  the  DIP 
switch on a Mac adapter may bounce an image slightly or may display nothing. Should this happen, set the DIP 
switch  to  the  13”  fixed  mode  and  then  restart  your  Macintosh.  After  that,  restore  the  DIP  switches  to  a  display-
able mode and then restart the Macintosh again.
NOTE:  A  Video  Adapter  cable  manufactured  by  Apple  Inc.  is  needed  for  a  PowerBook  which  does  not  have  a  mini  D-Sub 
15-pin connector.
•
 
Mirroring on a PowerBook
*
  When using the projector with a Macintosh PowerBook, output may not be set to 1024 x 768 unless “mirroring” 
is off on your PowerBook. Refer to owner’s manual supplied with your \
Macintosh computer for mirroring.
•
 
Folders or icons are hidden on the Macintosh screen
 
Folders or icons may not be seen on the screen. Should this happen, select [View] 
→ [Arrange] from the Apple 
menu and arrange icons.

and the screen size.
Available projection distances are 0.73 m/29 inches for 21" screen to 10.8 m/424 inches for 300" screen, according 
to the chart.
Us  ng the Chart
Example for 100" screen:
The projection distance is approximately 3.0 m (120") according to the\
 upper chart.
The lower chart shows that the vertical distance between the projector foot and the screen top is approximately 1.35 
m  (53").  The  projection  angle  can  be  adjusted  up  to  10°.  (The  lower  chart  shows  that  the  projector  is  placed  in  a
