Hiding the image

In order to draw the audience's 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 

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 Yes and press MODE/ENTER to confirm.

To release panel key lock, use the remote control to enter the 

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 Yes 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
