Operating in a high altitude environment
We recommend you use the High Altitude Mode when your environment is higher than
3200 feet above sea level, or is hotter than 40
°C, or whenever the projector will be used for
extended periods of time (>10 hours) without shutdown.
To activate the High Altitude Mode, go to
SYSTEM SETUP: Advanced > High
Altitude Mode,
select On by pressing Left/
Right on the projector or remote control. A
confirmation message displays. Highlight Ye s
and press 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.
Hiding the image
In order to draw the audience's full attention to the
presenter, you can use BLANK on the projector and
remote control to hide the screen image. Press any
button (except LASER) on the projector and remote
control to restore the image. The word 'BLANK'
appears at the lower right 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.
You can set a time length in the
SYSTEM SETUP:
Basic > Blank Timer
menu to shut down the projector after a period of time when there is
no action taken on the projector or remote control. 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 button (except LASER) anytime you
want to restore the image.
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 is used when the
environment is higher than 3200 feet,
or the temperature is over 40°C.
