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–35°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
:
1.
Press
MENU/EXIT
and then press / until the
SYSTEM SETUP: Advanced
menu is highlighted.
2.
Press
to
highlight
High Altitude Mode
and press
/
select
On
. A
confirmation message is displayed.
3.
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.
Creating your own startup screen
In addition to selecting the projector preset startup screen from among BenQ logo, Black
or Blue screen, you can make your own startup screen that is a picture projected from
your computer or video source.
To create your own startup screen, project the picture you want to use as your startup
screen from either a computer or video source. The rest steps are as follows.
