*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.

High Altitude
A mode for extreme environments like high altitude and high 
temperature. We recommend you use the High Altitude mode when your 
environment is higher than 3000 feet above sea level, or is hotter than 
40℃.
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 environments excluding the 
above, it may display auto shut-down symptoms, which is designed to 
protect your BenQ 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 environments.

Maintenance

Maintenance
Your projector needs little maintenance. The only things you have to do on a regular basis 
are to keep the lens clean and to clean the dust filters to prevent overheating.
Never remove any parts of the projector except the lamp and dust filters. Contact your dealer 
if other parts need replacing.
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface. 
Q Use a canister of compressed air to remove dust. 
Q If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner 
to gently wipe the lens surface.
Never rub the lens with abrasive materials.
Cleaning the projector case
Before you clean the case, turn the projector off and unplug the power cord.
Q To remove dirt or dust, wipe the case with a soft, dry, lint-free cloth.
Q To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral detergent. Then wipe the case.
Never use wax, alcohol, benzene, thinner or ot her chemical detergents. These can damage the 
case.
Cleaning and replacing the dust filters
It is necessary to clean the dust filters periodically. If the filters are not cleaned, they can 
become clogged with dust and prevent proper  ventilation. This can cause overheating and a 
malfunction of the projector.
A warning message like the one pictured to the 
right will be displayed for 10 seconds every 300 
hours to remind you to clean the filters.
1. Turn the project off and wait until the fans 
stop running.
2. Disconnect the projector from any cables.
3. Open one dust filter cover from the right and another one from the front of the  projector.
