							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 projectors 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 manufacturers 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.

Obtaining a preferred projected image size
The distance from the projector lens to the screen, the zoom setting, and the video format 
each factors in the projected image size.
Projection dimensions 
Refer to Dimensions on page 54 for the center of lens dimensions of this projector 
before calculating the appropriate position.

For example, if you are using a 120-inch screen, the recommended projection distance is 
1263 mm and the vertical offset is 81 mm.
If your measured projection distance is 1.5 m (1500 mm), the closest match in the 
Distance from screen (mm) column is 1579 mm. Looking across this row shows that a 
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 projectors 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 notebooks documentation to find your notebooks 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.
