Note:
• There is 5% tolerance among these numbers due to optical component variations. BenQ recommends that
if you intend to permanently install the projector, you should physically test the projection size and distance
using the actual projector 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.
Mounting the projector
If you intend to mount your projector, we strongly recommend that you use a proper tting 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.
English
• 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 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.

Connection
Before connecting
• Before connecting, carefully read the operating instructions for connecting the external device
• Turn off the power to all devices before connecting cables.
• Take note of the following before connecting cables. Failure to do so may result in
malfunctions.
• Before connecting a cable to the projector or to a device that is connected to the
projector, touch any nearby metallic objects to remove any static electricity from your
body.
• Do not use unnecessarily long cables to connect the projector or a device to the projector.
Using a longer cable that is wound makes it act like an antenna, making it more susceptible
to noise.
• When connecting cables, connect GND rst and then insert the connecting terminal of the
connecting device.
• Acquire any connection cables necessary to connect external devices to the system that are
not supplied.
• The images on the screen may wobble if the video signal contains too much jitter. In this case,
a time base corrector (TBC) must be connected.
English
• If synchronization signal outputs from computers or video equipment are disrupted due to
changes in the video output settings or any other reasons, the colors of projected images may
be temporarily disrupted.
• Some computer models are not compatible with the projector.
• Use a cable compensator when you connect devices to the projector with long cables. If a
cable compensator is not used, the image may not display properly.

Connecting audio
The projector has built-in mono speaker(s) which are designed to provide basic audio
functionality accompanying data presentations for business purposes only. They are not
designed for, nor intended for stereo audio reproduction use as might be expected in home
theater or home cinema applications. Any stereo audio input (if provided), is mixed into a
common mono audio output through the projector speaker(s).
The built-in speaker(s) will be muted when the AUDIO OUT jack is connected.
Note:

colors consisted of more proportions of
its two adjacent colors. Please refer to the
illustration for how the colors relate to
each other.
Wh it e
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 reect 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.
Saturation is the amount of that color in a video picture. Lower settings produce
less saturated colors; a setting of “0” removes that color from the image entirely. If
the saturation is too high, that color will be overpowering and unrealistic.
• Gain: Adjusts the values to your preference. The contrast level of the
primary color you select will be affected. Every adjustment made will
reect to the image immediately.
