Hiding the image
In order to draw the audience's full attention to the presenter, you can press BLANK to hide
the screen image. Press any key 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.
You can set the blank time in the
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.
Once Blank is pressed, the projector enters Eco mode automatically.
CAUTION
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. Press (Panel Key Lock), or go to the
SYSTEM > Panel Key Lock menu
2. Press Enter and press / to select On.
3. A confirmation message is displayed. Select Yes to confirm.
To release panel key lock, press and hold on the projector for 3 seconds.
You can also use the remote control to enter the
SYSTEM > Panel Key Lock menu and
select Off.
Keys on the remote control are still functional 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.
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 temperature is between 0°C–30°C.
CAUTION
Do not use the High Altitude Mode if your altitude is between 0 m and 1499 m and temperature
is between 0°C and 35°C. The projector will be over cooled, if you turn the mode on under
such a condition.
