Over-Temperature Protection
If the temperature inside the projector rises too high, the over-tempera\
ture protector will automatically turn off the
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.
•W ait about 60 minutes until the inside of the projector becomes cool enou\

mode •
Check that the power cable is plugged in and that the power button on th\
e projector cabinet or the remote
control is on. ( → pages  17 and  18)
• Ensure that the lamp cover is installed correctly. ( → page  52)
• Check to see if the projector has overheated. If there is insufficient v\
entilation 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 the lamp usage exceeds 2100 hours (up to 3100 hours : E\
co mode). If so, replace the lamp.
After replacing the lamp, reset the lamp hours used. ( → page  47)
• 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 co\
uld shut down. If this happens, wait a
couple minutes and turn on the projector. ( → page  45)
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.
• Ensure that the Power Management or Off Timer is off. ( → page  44)
• Use the COMPUTER1, the COMPUTER2, the VIDEO or the S-VIDEO button on the\
 remote control to select
your source (Computer, Video or S-Video). ( → page  20) If there is still no picture, press the button again.
• Ensure your cables are connected properly.
• Use menus to adjust the brightness and contrast. ( → page  40)
• Remove the lens cap.
• Reset the settings or adjustments to factory preset levels using the [Reset] in the Menu. ( → page  47)
• Enter your registered keyword if the Security function is enabled. ( → page  29)
• 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 un\
less connected to the projector
before being powered up.
*If the screen goes blank while using your remote control, it may be the \
result of the computers screen-
saver or power management software.
• See also the next page.
• When one of the following happens, the Lamp mode automatically changes f\
rom Normal to Eco.
*When there are no signals  → To return to the Normal mode, select another available source.
* When the room where you re presenting is particularly warm  → Move the projector to a cooler location, or
set [Fan Mode] to [High]. ( → page  45)
• Check if an appropriate color is selected in [Wall Color]. If so, select an appropriate option. ( → page  42)
• Adjust [Hue] in [Picture]. ( → page  40)
• Reposition the projector to improve its angle to the screen. ( → page  21)
• Use the Keystone correction function to correct the trapezoid distortion\
. ( → page  23)
• Adjust the focus. ( → page  22)
• Reposition the projector to improve its angle to the screen. ( → page  21)
• Ensure that the distance between the projector and screen is within the \
adjustment range of the lens.
(→  page  10)
• Condensation may form on the lens if the projector is cold, brought into\
 a warm place and is then turned on.
Should this happen, let the projector stand until there is no condensati\
on on the lens.
• Set [Fan Mode] to other than [High Altitude] mode when using the project\
or 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  45)
• Use the COMPUTER1, the COMPUTER2, the VIDEO or the S-VIDEO button on the\
 remote control to select
your source (Computer, Video or S-Video). ( → page  20)
• Adjust the computer image manually with the Horizontal/Vertical in the [Image Options]. ( → page  41)
• Install new batteries.( → page  8)
• Make sure there are no obstacles between you and the projector.
• Stand within 22 feet (7 m) of the projector. ( → page  8)
• See the POWER/STATUS/LAMP Indicator. ( → page  53)
• Press the AUTO ADJ. button on the projector cabinet or the remote contro\
l. ( → page  25)
• Adjust the computer image manually with Clock/Phase in [Image Options] i\
n the menu. ( → page  41)

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 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 un\
less connected to the projector before
being powered up.
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. (→ page  46 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 wil\
l enable/disable the external display.
Usually, the combination of the ‘Fn” key along with one of the 12 functio\
n 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 i\
n 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 projec-
tor) 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 a\
nd the projector, changing the DIP
switch on a Mac adapter may bounce an image slightly or may display noth\
ing. 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 s\
et to 1024 x 768 unless “mirror-
ing” 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, sele\
ct [View]  → [Arrange] from the Apple
menu and arrange icons.

*** What is HDCP/HDCP technology? HDCP is an acronym for High-bandwidth Digital Content Protection. High b\
andwidth Digital Content
Protection (HDCP) is a system for preventing illegal copying of video \
data sent over a Digital Visual
Interface (DVI).
If you are unable to view material via the DVI input, this does not nece\
ssarily mean the projector is not
functioning properly. With the implementation of HDCP, there may be cases in which certain content is
protected with HDCP and might not be displayed due to the decision/inten\
tion of the HDCP community
(Digital Content Protection, LLC).
