Operations at high altitudes
We recommend using the  High Altitude Mode when the environment is at 1500 to 
3000 meters above sea level and the temperature is between 5°C to 25°\
C.
 Caution 
Do not activate High Altitude Mode if the environment is at 0 to 1500 meters above sea level \
and 
the temperature is between 5°C to 35°C.  
Activating High Altitude Mode under such circumstances will lead to excessive cooling of\
 the 
projector.
Activating High Altitude Mode:
1.  Open the OSD menu and enter  System Settings > 
High Altitude Mode menu.
2.  Press  and select ON. / will display a 
confirmation message.
3.  Select Ye s , and then press [Enter].
There is a chance that louder operational noises 
will be generated when using the projector in  High 
Altitude Mode . The reason for this is the increased 
fan speed necessary to improve overall system 
cooling and performance.
Using this projector under extreme environments that exceed the aforemen\
tioned 
limits may lead to auto-shutdown designed to prevent overheating of the \
projector. 
Under such circumstances, you should switch to  High Altitude Mode to solve these 
issues. However, this does not mean that this projector is able to operate under any 
and all harsh or extreme conditions.  
						

							37
Using the CEC function
This projector supports Consumer Electronics Control (CEC), allowing y\
ou to connect 
to connect to HDMI and achieve synchronized power ON/OFF operations. This 
means that when a device that also supports CEC is connected to the HDMI\
 input 
jack of the projector, switching off the power of the projector will also automatically 
switch off the power of the connected device. Switching on the power of the 
connected device will also automatically switch on the projector.
Activating the CEC function:
1.  Open the OSD menu and enter  Power management > Auto Power On  > CEC 
menu.
2.  Press / and select Enable.
	 To	ensure	proper	operations	of	the	CEC	function,	please	verify	that	the	target	device	has	been	
connected to the HDMI input jack via an HDMI cable and that the CEC func\
tion has been 
activated.
CEC function may not be usable according to the connected equipment.
3D functions
This projector also comes with 3D functions that offer greater depth and immersion 
when viewing 3D movies, videos, sports, and games. You would need a pair of 3D 
glasses when viewing 3D images and videos.
If the 3D signal comes from an HDMI 1.4a compatible device, this project\
or will look 
for a 3D Sync data signal. Once detected, the projector will automatical\
ly switch to 3D 
projection. Under other circumstances, you may need to manually select t\
he 3D Sync 
format to ensure that the proper projection of 3D images.
Selecting 3D Sync formats:
1.  Use the 3D button on the remote control to enter the  3D Settings menu or enter 
Advanced > 3D Settings menu.
2.  Press [Enter] to bring up the 3D Settings page.
3.  Highlight  3D Glasses  and press / to select DLP or 3D VESA.
  Once 3D Sync function has been activated:   
•	Brightness	of	the	projected	image	will	be	reduced.	  
•	Color	modes	cannot	be	adjusted.	  
•	Zoom	functions	can	only	enlarge	the	image	to	a	limited	degree.	  
If	the	3D	image	has	been	severely	inverted,	you	may	set	the	3D	Sync	Invert	function	to	[Invert]	
to correct this problem.
Using the projector under standby mode
A number of projector functions can be used under Standby Mode (plugged \
in to 
power but not switched on). To use these functions, please check that you have 
switched on the  Power management > Standby Settings  and its secondary menu 
items, and that the cables have been properly connected. Refer to the ch\
apter on
