For example, if you are using a 120-inch screen, the recommended projection distance is 3895
mm.
If your measured projection distance is 4200 mm, the closest match in the "Projection distance
(mm)" column is 4220 mm. Looking across this row shows that a 130'' (about 3.3 m) screen is
required.
To optimize your projection quality, we suggest doing the projection by referring to the values listed in the
non-gray rows.
All measurements are approximate and may vary from the actual sizes.
BenQ recommends that if you intend to permanently install the projector, you should physically test the
projection size and distance using the actual projector in situ before you permanently install it, so as to
make allowance for this projector's optical characteristics. This will help you determine the exact mounting
position so that it best suits your installation location.

If you intend to mount your projector, we strongly recommend that you use a proper fitting
BenQ projector mounting kit and that you ensure it is securely and safely installed.
If you use a non-BenQ brand projector mounting kit, there is a safety risk that the projector may
fall down due to an improper attachment through the use of the wrong gauge or length screws.
Before mounting the projector
• Purchase a BenQ projector mounting kit from the place you purchased your BenQ projector.
• BenQ recommends that you also purchase a separate Kensington lock compatible security
cable and attach it securely to both the Kensington lock slot on the projector and the base of
the mounting bracket. This will perform the secondary role of restraining the projector should
its attachment to the mounting bracket become loose.
• Ask your dealer to install the projector for you. Installing the projector on your own may cause
it to fall and result in injury.
• Take necessary procedures to prevent the projector from falling off such as during an
earthquake.
• The warranty doesn’t cover any product damage caused by mounting the projector with a
non-BenQ brand projector mounting kit.
• Consider the surrounding temperature where the projector is ceiling/wall mounted. If a heater
is used, the temperature around the ceiling/wall may be higher than expected.
• Read the user manual for the mounting kit about the range of torque. Tightening with torque
exceeding the recommended range may cause damage to the projector and subsequently
falling off.
• Make sure the power outlet is at an accessible height so that you can easily shut down the
projector.

• Color Management
The Color Management provides six sets (RGBCMY) of colors to be
adjusted. When you select each color, you can independently adjust its
range and saturation according to your preference.
To make adjustments, press the / arrows to highlight an independent
color from among Red (R), Green (G), Blue (B), Cyan (C), Magenta (M),
Yellow (Y) or White (W). The following menu items are displayed for your
choice.
• Hue: Increase in the range will include
colors consisted of more proportions of
its two adjacent colors. Please refer to
the illustration for how the colors relate
to each other.
For example, if you select Red and set its
range at 0, only pure red in the projected
picture will be selected. Increasing its
range will include red close to yellow and
red close to magenta.
• Saturation: Adjusts the values to your
preference. Every adjustment made will
reflect to the image immediately. For
example, if you select Red and set its
value at 0, only the saturation of pure red will be affected.
• Gain: Adjusts the values to your preference. The contrast level of the
primary color you select will be affected. Every adjustment made will
reflect to the image immediately.
If you select White Balance, you can adjust the contrast levels of Red,
Green, Blue, Cyan, Magenta, Yellow and White by selecting R Gain, G Gain,
and B Gain.
To return all the settings to the factory default values, highlight Reset, and

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–30°C.
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
High Altitude
Mode
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.
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.

Maintenance
Care of the projector
Cleaning the lens
Clean the lens whenever you notice dirt or dust on the surface. Please be sure to turn off the
projector and let it cool down completely before cleaning the lens.
• Use a canister of compressed air to remove dust.
• If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner and
gently wipe the lens surface.
• Never use any type of abrasive pad, alkaline/acid cleaner, scouring powder, or volatile solvent,
such as alcohol, benzene, thinner or insecticide. Using such materials or maintaining
prolonged contact with rubber or vinyl materials may result in damage to the projector surface
and cabinet material.
Cleaning the projector case
Before you clean the case, turn the projector off using the proper shutdown procedure as
described in Shutting down the projector on page 27 and unplug the power cord.
• To remove dirt or dust, wipe the case with a soft, lint-free cloth.
• To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral pH detergent.
Then wipe the case.
Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the case.
Storing the projector
If you need to store the projector for an extended time, please follow the instructions below:
• Make sure the temperature and humidity of the storage area are within the recommended
range for the projector. Please refer toSpecifications on page 51 or consult your dealer about
the range.
• Retract the adjuster feet.
• Remove the battery from the remote control.
• Pack the projector in its original packing or equivalent.
Transporting the projector
It is recommended that you ship the projector with its original packing or equivalent.
Light source information
Getting to know the light hour
When the projector is in operation, the duration (in hours) of light source usage is automatically
calculated by the built-in timer. The method of calculating the equivalent light hour is as
follows:
1. Light Usage Time = (x+y+z) hours, if
Time used in Normal mode = x hours
47 Maintenance
Page 48
Time used in ECO mode = y hours
α

Time used in SmartEco mode = z hours
Time used in Custom mode = a hours
2. Equivalent Light Hour = hours
X= light source life spec of Normal mode
Y= light source life spec of ECO mode
Z= light source life spec of SmartEco mode
A= light source life spec of Custom mode
A’ is the longest light life spec among X, Y, Z, A
For time used in each light mode shown in OSD menu:
• Time used is accumulated and rounded down to an integer in hours.
• When time used is less than 1 hour, it shows 0 hours.
When you calculate Equivalent Light Hours manually, it will probably have deviation from the value shown
in OSD menu since projector system calculates time used for each light mode in “Minutes” then rounds
down to an integer in hours shown in OSD.
, if
To obtain the light source hour information:
1. Go to Advanced Menu - Settings > Light Usage Time and press OK.
2. The Light Usage Time information is displayed.
You can also get the light source hour information on the Information menu.
Extending light source life
• Setting the Light Source Mode
Go to Advanced Menu - Picture > Advanced Color Settings > Light Source Mode and select a
suitable light source power from among the provided modes.
Setting the projector in ECO, SmartEco or Custom mode extends light source life.
