Hiding the image
In order to draw the audiences full attention to the presenter, you can use ECO BLANK 
on the projector or remote control to hide the screen image. When this function is 
activated with an audio input connected, the audio can still be heard. 
You can set the blank time in the 
SYSTEM SETUP: Basic > Operation Settings > 
Blank Timer menu to let the projector return the image automatically after a period of 
time when there is no action taken on the blank screen.
If the preset time spans are not suitable for your presentation, select Disable.
No matter 
Blank Timer is activated or not, you can press most of the keys on the 
projector or remote control to restore the picture.
Do not block the projection lens from projecting as this could cause the blocking object to become heated and 
deformed or even cause a fire.
Locking control keys
With the control keys on the projector locked, you can prevent your projector settings 
from being changed accidentally (by children, for example). When the Panel Key Lock is 
on, no control keys on the projector will operate except  POWER.
1. Go to the SYSTEM SETUP: Basic > Panel Key Lock menu, and select On by 
pressing  /  on the projector or remote control. A confirmation message 
appears. 
2. Highlight Ye s and press MODE/ENTER to confirm.
To release panel key lock, use the remote control to enter the 
SYSTEM SETUP: 
Basic > 
Panel Key Lock menu and press  /  to select Off.
•  Keys on the remote control are still active when panel key lock is enabled.
•  If you turn off the projector without disabling panel key lock, the projector will still be in locked status the 
next time it is turned on.
Operating in a high altitude environment
We recommend you use the High Altitude Mode when your environment is between 
1500 m –3000 m above sea level, and ambient temperature is between 0°C–35°C.
Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and ambient temperature is 
between 0°C and 35°C. The projector will be over cooled, if you turn the mode on under such a condition.
To activate the High Altitude Mode:
1. Press MENU/EXIT and then press  /  until the SYSTEM SETUP: Advanced 
menu is highlighted.
2. Press  to highlight High Altitude Mode and press  /  select On. A 
confirmation message appears.
3. Highlight Ye s and press MODE/ENTER.
Operation under High Altitude Mode may cause a higher decibel operating noise level 
because of increased fan speed necessary to improve overall system cooling and 
performance.
If you use this projector under other extreme conditions excluding the above, it may 
display auto shut-down symptoms, which is designed to protect your projector from over-
heating. In cases like this, you should switch to High Altitude mode to solve these

If you dont respond in a few seconds, the message will disappear.
2. Press  POWER a second time. The POWER indicator light flashes orange, 
the projection lamp shuts down, and the fans will continue to run for approximately 
90 seconds to cool down the projector.
To protect the lamp, the projector will not respond to any commands during the cooling process.
To shorten the cooling time, you can also activate the Quick cooling function. See Quick Cooling on page 41 
for details.
3. Once the cooling process finishes, a Power Off 
Ring Tone will be heard. The POWER indicator 
light is a steady orange and fans stop. Disconnect 
the power cord from the power outlet.
•  To turn off the power ring tone, see Turning off the Power On/

when you attempt to re-start the projector, the fans will run for a 
few minutes to cool down. Press   POWER again to start the 
projector after the fans stop and the POWER indicator light 
turns orange.
•  Lamp life results will vary depending on environmental conditions 
and usage.
Direct power off
The AC power cord can be pulled out right after the projector is turned off. To protect 
the lamp, wait about 10 minutes before re-starting the projector. (When you attempt to 
re-start the projector, the fans may run for a few minutes to cool down. In such cases, 
press  POWER again to start the projector after the fans stop and the POWER

Function Description
3D
This projector features a 3D function which enables you to enjoy the 
3D movies, videos, and sporting events in a more realistic way by 
presenting the depth of the images. You need to wear a pair of 3D 
glasses to view the 3D images.
3D Mode
The default setting is Auto and the projector automatically chooses 
an appropriate 3D format when detecting 3D contents. If the projector 
cannot recognize the 3D format, press  /  to choose a 3D mode. 
When the 3D function is on:
• The brightness level of the projected image will decrease.
•  The Picture Mode cannot be adjusted.
3D Sync Invert
When you discover the inversion of the image depth, enable this 
function to correct the problem.
Apply 3D Settings
After the 3D settings are saved, you can decide if you would like to 
apply them by choosing a set of 3D settings that you have saved. Once 
applied, the projector will automatically play the incoming 3D contents 
if it matches the 3D settings saved.
Only the set(s) of 3D settings with memorized data is available. 
Save 3D Settings
When you have successfully displayed the 3D contents after making 
the appropriate adjustments, you can enable this function and choose 
a set of 3D settings to memorize current 3D settings.
