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
SYSTEM SETUP: Basic > Operation Settings >
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.

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–30°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
:

SYSTEM SETUP: Advanced
menu is highlighted.

High Altitude Mode

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
