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.
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.
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 Ye s and
press Mode/enter on the projector or ENTER on the
remote control.
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.
•Using the remote control
1. Press CAPTURE on the remote control.
2. A confirmation message displays. Press CAPTURE
or ENTER again.
3. The message 'Screen Capturing...' displays while the
projector is processing the picture. Please wait.
4. If the action is successful, you see the message
'Captured Succeeded' on the screen. The captured
picture is saved as My Screen.
5. To view the captured picture displayed as the startup
screen, set My Screen in the SYSTEM SETUP: Basic
> Splash Screen menu and restart the projector.
•Using the OSD menu
1. Press MENU/EXIT and then press / until the SYSTEM SETUP: Basic menu is
highlighted.
2. Press to highlight My Screen and press Mode/enter.
3. Repeat steps 2-5 in the “Using the remote control” section to capture and view the
captured picture.
In the unlikely event that the capturing action fails, change your target picture.
We recommend you use the High
Altitude Mode by selecting it
whenever your environment is
higher than 1500 m.
