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. The word
'BLANK' appears in the 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.
Once BLANK is pressed, the projector lamp enters
Economic mode automatically.
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. The length of time can be set from 5
to 30 minutes in 5-minute increments.
If the preset time spans are not suitable for your
personation, select Disable.
No matter
Blank Timer is activated or disabled,
you can press any key on the remote control to
restore the picture.
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–35°C.
To activate the High Altitude Mode, go to the
SYSTEM SETUP: Advanced > High Altitude
Mode, select On by pressing / on the
projector or remote control. A confirmation
message displays. Highlight Yes and press
Mode/Enter.
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.
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 symptoms. However, this is not to
state that this projector can operate under any
and all harsh or extreme conditions.
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.
We recommend you use the High
Altitude Mode by selecting it
whenever your environment is
higher than 1500 m.
Do you want to turn High Altitude
Mode on?
Yes No
Notice
CAUTION
Do not use the High Altitude Mode
if your altitude is between 0 m and
1500 m and temperature is
between 0°C and 35°C. The
projector will be over cooled, if
you turn the mode on under such
condition.
