Operating the LASER pointer

The Laser Pointer is a presentation aid for professionals. It emits red colored light when you press it.

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.

Introduction12

Remote control effective range

• Operating the projector from the front

• Operating the projector from the rear

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.

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.

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 44 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

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.

• The projector is only capable of playing mixed mono audio, even if a stereo audio input is connected. See "Connecting audio" on page 17 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.

Connection 17

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 43 for details.

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

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

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+/VOLUME- on 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.

• 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.
