x Replacing or Cleaning the Filter
To replace the filter:
• Replace both filters at the same time.
• Before replacing the filters, remove dust and dirt from the pro-
jector cabinet.
• The projector contains high-precision parts. Keep out dust and
dirt during filter replacement.
• Do not wash the filter with water. Water will damage the filter
membrane.
• Reattach the filter cover correctly. Failure to do so may cause
projector malfunction.
Preparation: Replace the lamp before replacing the filters.
1. Pull out the filter cover by pushing up on the catch.
The "Please clean the filters" message will be displayed each
time the projector is turned on after it has been used in excess of
168 hours. Should this message appear, clean the filters.
NOTE:
* The message can be turned on or off using the "Message" option on the Setup
menu. See page 8-14.
* After cleaning the filters and resetting the filter usage time back to zero, the mes-
sage will not be displayed.
See page 8-17 for resetting the filter usage time.

tended life lamp GT60LPS), turn off the main power and unplug the
projector before replacing the filter.
• Do not attempt to operate the projector without filter.
• Your projector will not operate unless the filter cover is installed cor-
rectly.
To clean the filter:
Pull out the filter by pushing up on the catch. Vacuum the filter-
through the filter.

9 and 2-11.
• Ensure that the lens hood or the lamp cover is installed correctly. See pages 1-4 and 9-2.
• Check to see if the projector has overheated or the lamp has reached the end of its usable life. If there is
insufficient ventilation around the projector or if the room where you’re presenting is particularly warm, move
the projector to a cooler location.
• The lamp may fail to light. Wait a full minute and then turn on the power again.
• The lamp has reached the end of its usable life. Replace the lamp.
• Ensure that the Power Management is off. See page 8-16.
• Use the menu or Source/Input button to select your source (RGB 1/2, DVI, Video, S-Video, Viewer or LAN).
See page 3-3 or 8-7.

• If Security is enabled, a keyword or PC card as a protect key is required.
• Remove the lens cap.
• When using with a notebook PC, be sure to connect between the projector and the notebook PC before turning
on the power to the notebook PC. In most cases signal cannot be output from RGB output unless the notebook
PC is turned on after connecting with the projector.
* If the screen goes blank while using your remote control, it may be the result of the computer's screen-saver
or power management software.
* If you accidentally hit the POWER button on the remote control, wait 60 seconds and then press the POWER
button again to resume.
• See also the next page.
• Reposition the projector to improve its angle to the screen. See page 3-3.

10. Appendix
If there is no picture, or the picture is not displayed correctly.
• Power on process for the projector and the PC.
Be sure to connect the RGB cable between the projector and the computer before turning on the computer. There are some
notebook PCs, which do not output signal unless there is a projectors or monitor connected first.
NOTE: You can check the horizontal frequency of the current signal in the projector’s menu under Information.  If it reads “0kHz”, this means
there is no signal being output from the computer. See page 8-29 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 projector.  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 previous step. Refer to your computer’s
documentation for detailed information.
• Image displayed is incorrect when using a Macintosh
When using a Macintosh with the projector, set the DIPswitch of the Mac adapter (not supplied with the projector) according to
your resolution. After setting, restart your Macintosh 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 displayable mode and then restart the Macintosh
again.
NOTE: A Video Adapter cable manufactured by Apple Computer 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.
