Important safety instructions6
Safety Instructions (Continued)
Ceiling mounting the projector
We want you to have a pleasant experience using your BenQ projector, so we need
to bring this safety matter to your attention to prevent possible damage to person
and property.
If you intend to mount your projector on the ceiling, we strongly recommend that
you use a proper fitting BenQ projector ceiling mount kit and that you ensure it is
securely and safely installed.
If you use a non-BenQ brand projector ceiling mount kit, there is a safety risk that
the projector may fall from the ceiling due to an improper attachment through the
use of the wrong gauge or length screws.
You can purchase a BenQ projector ceiling mount 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 ceiling mount bracket. This
will perform the secondary role of restraining the projector should its attachment to
the mounting bracket become loose.

Introduction 13
Remote control effective range
Infra-Red (IR) remote control sensors are located on the front and the rear of the
projector. The remote control must be held at an angle within 30 degrees perpendicular to
the projector's IR remote control sensors to function correctly. The distance between the
remote control and the sensors should not exceed 8 meters (~ 26 feet).
Make sure that there are no obstacles between the remote control and the IR sensors on
the projector that might obstruct the infra-red beam.
Replacing the remote control batteries
1. To open the battery cover, turn the remote control over to view its back, push on
the finger grip on the cover and slide it up in the direction of the arrow as illustrated.
The cover will slide off.
2. Remove any existing batteries (if necessary) and install two AAA batteries observing
the battery polarities as indicated in the base of the battery compartment. Positive
(+) goes to positive and negative (-) goes to negative.
3. Refit the cover by aligning it with the base and sliding it back down into position. Stop
when it clicks into place.
Avoid leaving the remote control and batteries in an excessive heat or humid environment like the
kitchen, bathroom, sauna, sunroom or in a closed car.
Replace only with the same or equivalent type recommended by the battery manufacturer.
Dispose of the used batteries according to the manufacturer's instructions and local environment
regulations for your region.
Never throw the batteries into a fire. There may be danger of an explosion.
If the batteries are dead or if you will not be using the remote control for an extended period of time,
remove the batteries to avoid damage to the remote control from possible battery leakage.

150'' (about 3.8 m) screen is required.
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.

Many notebooks do not turn on their external video ports when connected to a projector. Usually a key
combo like FN + F3 or CRT/LCD key turns the external display on/off. Locate a function key labeled CRT/
LCD or a function key with a monitor symbol on the notebook. Press FN and the labeled function key
simultaneously. Refer to your notebook's documentation to find your notebook's key combination.
The D-Sub output only works when an appropriate D-Sub input is made to the COMPUTER 1 jack.
If you wish to use this connection method when the projector is in standby mode, make sure the
Monitor Out function is turned on in the SYSTEM SETUP: Advanced menu. See "Standby Settings"
on page 46 for details.
Connecting video source devices
You need only connect the projector to a video source device using just one of the
connecting methods, however each provides a different level of video quality. The method
you choose will most likely depend upon the availability of matching terminals on both the
projector and the video source device as described below:
Connecting audio
The projector has two built-in mono speakers 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 speakers.
The built-in speakers will be muted when the AUDIO OUT jack is connected.
In the unlikely event that you connect the projector to a DVD player via the projector’s HDMI input and
the projected picture displays wrong colors, please change the color space to YUV. See "Changing Color
Space" on page 27 for details.
The projector is only capable of playing mixed mono audio, even if a stereo audio input is connected. See
"Connecting audio" on page 18 for details.
If the selected video image is not displayed after the projector is turned on and the correct video source
has been selected, check that the video source device is turned on and operating correctly. Also check
that the signal cables have been connected correctly.
Playing sound through the projector
You can make use of the projector (mixed mono) speaker in your presentations, and also
connect separate amplified speakers to the AUDIO OUT socket of the projector.
If you have a separate sound system, you will most likely want to connect the audio output
of your Video source device to that sound system, instead of to the mono audio projector.
You can also use a microphone to output the sound through the projector speaker.

Connection 19
Once connected, the audio can be controlled by the projector On-Screen Display (OSD)
menus. See "Audio Settings" on page 45 for details.
The table below describes the connection methods for different devices, and where the
sound is from.
The projector can play sound if the connected RJ45 cable or USB cable carries audio signal. There is no need
to connect the audio cable when the USB Display or Network Display source is selected.
About the microphone input
If you wish to use a microphone, connect a 3.5 mini jack cable microphone to the
projector.
You can use a wireless microphone as long as a wireless module is attached to the
projector’s microphone input jack and it works well with the associated devices. To
ensure a quality use of the wireless microphone, it is recommended that your
microphone conforms to the specifications listed in the table below.
There are two ways to adjust microphone volumes.
Directly set microphone volume levels in the SYSTEM SETUP: Advanced
> Audio Settings > Microphone Volume menu.
•Press MIC/VOL keys (+/-) on the remote control.
To make the microphone input available when the projector is in standby mode, turn
on the SYSTEM SETUP: Advanced > Standby Settings > Microphone menu.
If the microphone is not working, check the volume setting and cable connection.
You might get feedback noise from the microphone when you are too close to the
speaker of the projector. Move the microphone away from the speaker of the
projector. The greater volume you require, the greater distance you need to be away
from the speaker to prevent the noise.

the projector doesn't detect a valid signal, the message “No Signal” will continue
displaying until an input signal is found.
You can also press SOURCE on the projector or remote control to select your
desired input signal. See "Switching input signal" on page 27 for details.
If the frequency/resolution of the input signal exceeds the projector's operating range, you will see the
message “Out of Range” displayed on a blank screen. Please change to an input signal which is compatible with
the projector's resolution or set the input signal to a lower setting. See "Timing chart" on page 57 for details.
