Hiding the image
In order to draw the audience's full attention to the presenter, you can press
Blank
on the
projector or remote control 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 SuperEco 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.

High Altitude Mode
when your environment is between 1500
m–3000 m above sea level, and temperature is between 5°C–25°C.
CAUTION
Do not use the High Altitude Mode if your altitude is between 0 m and 1499 m and temperature
is between 5°C and 35°C. The projector will be over cooled, if you turn the mode on under
such a condition.

Altitude Mode

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.
