BenQ Gp1 Dlp Users Manual

							Operation 31 The options available for color temperature* settings vary according to the signal type 
selected.
1.T1: With the highest color temperature, T1 makes the image appear the most bluish 
white than other settings.
2.T2: Makes images appear bluish white.
3.T3: Maintains normal colorings for white.
*About color temperatures:
There are many different shades that are considered to be white for various purposes. One 
of the common methods of representing white color is known as the “color temperature”. A 
white color with a low color temperature appears to be reddish white. A white color with a 
high color temperature appears to have more blue in it.
Hiding the image
In order to draw the audiences full attention to the 
presenter, you can use BLANK on the projector or 
remote control to hide the screen image. Press any key 
on the projector or remote control to restore the 
image. The word BLANK appears at the lower right 
corner of the screen while the image is hidden.
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. 
Once BLANK is pressed, the projector enters Economic mode automatically.
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.
Freezing the image
Press FREEZE on the remote control to freeze the 
image. The word FREEZE will display in the upper 
left corner of the screen. To release the function, press 
any key on the projector or remote control.
Even if an image is frozen on the screen, the pictures 
are running on the video or other device. If the 
connected devices have active audio output, you will 
still hear the audio even though the image is frozen on 
screen.

							Operation 32
Operating in a high altitude environment
We recommend you use the High Altitude Mode when your environment is between 1500 m 
–4000 m above sea level, and temperature is between 5°C–35°C.
Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and temperature 
is between 5°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  /  to select On. A confirmation 
message displays.
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.

sure you have made a correct connection to the projector audio input. See Connection on 
page 15 for how the audio input is connected.

To temporarily turn off the sound:
1. Press MENU/EXIT and then press  /  until 
the SYSTEM SETUP: Advanced menu is 
highlighted.

MODE/ENTER. The Audio Settings page 
displays.
3. Highlight Mute and press  / to select On.

Ring LED indicator lights blue and fans stop.
4. Disconnect the power cord from the wall socket if the projector will not be used in an 
extended period of time.
