Hiding the image
In order to draw the audience’s attention to the presenter, you may press Blank
to hide the screen image. Press any key on the projector or remote to restore the
image. After hiding the image, the lower right corner of the screen will display the text
[Blank].
You can go to Basic > Blank Timer menu to set blank screen duration. Once the
blank screen countdown is complete, the image will be automatically re-displayed.
After pressing [Blank], the projector will automatically enter Power Saving mode.
Caution
Do not block the projector lens. The blocking item may be heated to the point of deformation or
may even cause a re.
Locking control keys
Locking the control buttons of the projector allows you to prevent projector settings
from being changed accidentally (by children, for example). Once Panel Key Lock
has been activated, with the exception of the Power button, none of the buttons on
the projector could be used.
1. Go to System > Panel Key Lock menu.
2. Press / and select ON.
To switch off the Panel Key Lock, press and hold the button on the Projector for 3
seconds.
You may also use the remote to enter System > Panel Key Lock menu, press /
and select OFF.
Buttons on the remote control can still be used even if the Panel Key Lock function has been
switched on.
If you press the Power button to switch off the projector without switching off the Panel Key
Lock function, the projector buttons will remain locked when you switch it on the next time.
