Important safety instructions

Your projector is designed and tested to meet the latest standards for safety of information technology equipment. However, to ensure safe use of this product, it is important that you follow the instructions mentioned in this manual and marked on the product.

Safety Instructions

1.Please read this manual before you operate your projector. Save it for future reference.

2.Do not look straight at the projector lens during operation. The intense light beam may damage your eyes.

3.Refer servicing to qualified service personnel.

5.In some countries, the line voltage is NOT stable. This projector is designed to operate safely within a mains voltage between 100 to 240 volts AC, but could fail if power cuts or surges of 10 volts occur. In areas where the mains voltage may fluctuate or cut out, it is recommended that you connect your projector through a power stabilizer, surge protector or uninterruptible power supply (UPS).

6.Do not block the projection lens with any objects when the projector is under operation as this could cause the objects to become heated and deformed or even cause a fire. To temporarily turn off the lamp, press BLANK on the projector or remote control.

4.Always open the lens shutter (if any) or remove the lens cap (if any) when the projector lamp is on.

18.Do not place liquids near or on the projector. Liquids spilled into the projector may cause it to fail. If the projector does become wet, disconnect it from the power supply's power outlet and call BenQ to have the projector serviced.

19.This product is capable of displaying inverted images for ceiling mount installation.

Use only BenQ's Ceiling Mount Kit for mounting the projector and ensure it is securely installed.

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.

Hg - Lamp contains mercury. Manage in accordance with local disposal laws. See www.lamprecycle.org.

20.This apparatus must be earthed.

Operating the LASER pointer

The Laser Pointer is a

presentation aid for professionals. It emits red colored light when you press it and the indicator lights up red.

The laser beam is visible. It is necessary to press and hold LASER for continuous output.

Do not look into the laser light window or

shine the laser light beam on yourself or others. See the warning messages on the back of the remote control prior to using it.

The laser pointer is not a toy. Parents should be mindful of the dangers of laser energy and keep this remote control out of the reach of children.

12 Introduction

Remote control effective range

Infra-Red (IR) remote control sensors are located on the front and the back 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.

Introduction 13

Positioning your projector

Choosing a location

Your projector is designed to be installed in one of four possible installation locations:

1.Front Table

Select this location with the projector placed on the table in front of the screen. This is the most common way to position the projector for quick setup and portability.

2.Front Ceiling

Select this location with the projector suspended upside-down from the ceiling in front of the screen.

Purchase the BenQ Projector Ceiling Mount Kit from your dealer to mount your projector on the ceiling.

Set Front Ceiling in the SYSTEM SETUP: Basic > Projector Position menu after you turn the projector on.

3.Rear Ceiling

Select this location with the projector suspended upside-down from the ceiling behind the screen.

Note that a special rear projection screen and the BenQ Projector Ceiling Mount Kit are required for this installation location.

Set Rear Ceiling in the SYSTEM SETUP: Basic > Projector Position menu after you turn the projector on.

4.Rear Table

Select this location with the projector placed on the table behind the screen.

Note that a special rear projection screen is required.

Set Rear Table in the SYSTEM SETUP: Basic > Projector Position menu after you turn the projector on.

Your room layout or personal preference will dictate which installation location you select. Take into consideration the size and position of your screen, the location of a suitable power outlet, as well as the location and distance between the projector and the rest of your equipment.

14 Positioning your projector

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 73 for the center of lens dimensions of this projector before calculating the appropriate position.

	300	7620	6096	4572	3704	686

For example, if you are using a 120-inch screen, the recommended projection distance is 1481 mm and the vertical offset is 274 mm.

If your measured projection distance is 1.0 m (1000 mm), the closest match in the "Distance from screen (mm)" column is 988 mm. Looking across this row shows that a 80'' (about 2.0 m) screen is required.

For example, if you are using a 120-inch, 4:3-aspect-ratio screen and the projected picture is 16:10, please refer to Table B2 on page 17, the recommended projection distance is 1192 mm and the vertical offset is 76 mm.

If you need a 16:9 screen to project a 16:9 picture and your measured projection distance is 1.5 m (1500 mm), please refer to Table A1 on page 16. The closest match in the "(b) Distance from screen" column is 1623 mm. Looking across this row shows that a 150'' (about 3.8 m) screen is required.

There is 3% 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 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 62 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:

Terminal name	Terminal appearance	Picture quality
HDMI		Best
(MX762 ST only)
Component Video		Better
S-Video		Good
Video		Normal

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 (MX762 ST only)" on page 30 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 20 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.

20 Connection

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.

Once connected, the audio can be controlled by the projector On-Screen Display (OSD) menus. See "Audio Settings" on page 61 for details.

The table below describes the connection methods for different devices, and where the sound is from.

Device	PC/Component Video	Video/S-Video		Microphone
Audio input port	AUDIO IN 1	AUDIO IN 2 (L/R)		MIC
The projector can			•	MIC
play the sound	AUDIO IN 1/MIC	AUDIO IN 2 (L/R)/MIC	•	AUDIO IN 1/MIC
from...			• AUDIO IN 2 (L/R)/
				MIC
Audio output port	AUDIO OUT	AUDIO OUT		AUDIO OUT

The selected input signal determines which sound will be played by the projector speaker, and which sound will be output from the projector when AUDIO OUT is connected. If you select a PC signal, the projector can play the sound received from AUDIO IN 1/MIC.

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.

Signal	Parameter	Min	Type	Max
	Transducer Principle				Dynamic
Microphone	Impedance	300		1K	ohm
	Frequency response	600		16k	Hz

•There are two ways to adjust microphone volumes.

•Directly set microphone volume levels in the SYSTEM SETUP: Advanced > Audio Settings > Microphone Volume menu or press MIC/VOL keys (+/-) on the remote control.

•Set projector volume levels in the SYSTEM SETUP: Advanced > Audio Settings > Volume menu, or press VOLUME+/VOLUMEon the remote control. (The projector volume setting will affect the microphone volume.)

•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.

Connection 21

•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.

Operation

Starting up the projector

1.Plug the power cord into the projector and into a

power outlet. Turn on the power outlet switch (where fitted). Check that the POWER indicator light on the projector lights orange after power has been applied.

Please use the original accessories (e.g. power cord) only with the device to avoid possible dangers such as electric shock and fire.

2.Press POWER on the projector or ON on the remote control to start the projector. As soon as the lamp lights up, a "Power On Tone" will be heard. The POWER indicator light flashes green and stays green when the projector is on.

The start up procedure takes about 30 seconds. In the later stage of start up, a startup logo is projected.

(If necessary) Rotate the focus ring to adjust the image clearness.

To turn off the ring tone, see "Turning off the Power On/Off Ring Tone" on page 39 for details.

If the projector is still hot from previous activity, it will run the cooling fan for approximately 90 seconds before energizing the lamp.

3.If the projector is activated for the first time, select your OSD language following the onscreen instructions.

4.If you are prompted for a password, press the arrow keys to enter a six-digit password. See "Utilizing the password function" on page 27 for details.

5.Switch all of the connected equipment on.

6.The projector will start to search for input signals. The current input signal being scanned displays in the upper left corner of the screen. If

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 30 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 74 for details.
