Hiding the image
In order to draw the audience's full attention to 
the presenter, you can use BLANK on the 
projector or remote control to hide the screen 
image. Press any button on the projector or 
remote control to restore the image.
 
The word 
'BLANK' appears at the lower right corner of 
the screen while the image is hidden. 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 > 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. 
Locking control keys
To prevent unauthorized changes in the settings or accidental button pushes, panel key 
lock can be activated to disable all panel key functions except POWER.
1.
Press 
/
 on the projector or remote 
control or go to SYSTEM SETUP: Basic > 
Panel Key Lock
, and select On by pressing 
 on the projector or remote control. 
2.
A confirmation message displays. Select 
Yes to confirm.
To release panel key lock, press and hold

 for 3 seconds on the projector or remote 
control.
You can also use the remote control to enter SYSTEM SETUP: Basic > Panel Key 
Lock
 and press 
 to select Off. A confirmation message displays. Select Yes to 
confirm.
Buttons on the remote control are still in use when panel key lock is enabled.
If you press POWER to turn off the projector without disabling panel key lock, the 
projector will still be in locked status the next time it is turned on.
Once BLANK is pressed, the 
projector lamp enters Economic 
mode automatically.
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.
