A mode for extreme environments like high altitude and high tempera-
ture. We recommend you use the High Altitude mode when your environ-
ment is higher than 3000 feet, or is hotter than 40℃.
Operation under "High Altitude Mode" may cause a higher decibel oper-
ating noise level because of increased fan speed necessary to improve over-
all system cooling and performance.
High Altitude
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.

Your projector needs little maintenance. Things you have to do on a regular basis are keep
the lens clean and clean the air filter to prevent overheating.
Never remove any parts of the projector except the lamp and air filter. Contact your dealer if
other parts needs replacing.
Cleaning the lens

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.
ꢀ To remove dirt or dust, wipe the case with a soft, dry, lint-free cloth.
ꢀ 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 other chemical detergents. These can damage the
case.
Cleaning and replacing the air filters
It is necesssary to clean the air 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.

To reduce the risk of injuries to fingers and/or compromising image quality by touching the
lens, do not touch the empty lamp compartment when the lamp is removed.
This lamp contains mercury. Consult your local hazardous waste regulations and dispose of
this lamp in the proper manner.
Step 1. Turn the power off and disconnect the projector from the wall socket.
Step 2. Turn the projector over. Then loosen the
screws and remove the lamp cover. If the
lamp is hot, avoid burns by waiting for 45
minutes until the lamp has cooled.
Step 3. Loosen the screw that fixes the lamp to the
projector. If the screw is not loosened
completely, you could injure your
fingers. It is strongly recommended that
you use a magnetic-head screwdriver.
Step 4. Lift the handle so that it stands up. Use the
handle to slowly pull the lamp out of the
projector.
Pulling too quickly may cause the lamp to break
and scatter broken glass in the projector.
Do not place the lamp in locations where water
might splash on it, children can reach it, or near
flammable materials.
Do not insert your hands into the projector after
the lamp is removed. If you touch the optical com-
ponents inside, it could cause color unevenness and distortion of the projected images.
Step 5. Insert the new lamp. Make sure the handle is fully locked and tighten the screw
firmly.
A Loose screw may cause a bad connection, which could result in malfunction.
Do not over tighten the screw.
Step 6. Re-install the lamp cover and tighten the
screw. Do not turn the power on with the
lamp cover removed. Whenever the lamp
is replaced, reset the total lamp operation
timer. Do not reset if the lamp is not
replaced as this could cause damage.
