Introduction 11

Remote control effective range

Infra-Red (IR) remote control sensor is located on the front of the projector. The remote control must be held at an angle within 30 degrees perpendicular to the projector's IR remote control sensor to function correctly. The distance between the remote control and the sensor should not exceed 7 meters (~ 23 feet).

5°

Make sure that there are no obstacles between the remote control and the IR sensor on the projector that might obstruct the infra-red beam.

Replacing the remote control battery

1. Pull out the battery holder.

Please follow the illustrated instructions. Push and hold the locking arm while pulling out the battery holder.

2. Insert the new battery in the holder. Note the positive polarity should face outward.

3. Push the holder into the remote control.

• Avoid excessive heat and humidity.

• There may be battery damage if the battery is

incorrectly replaced.

• Replace only with the same or equivalent type recommended by the battery manufacturer.

• Dispose of the used battery according to the battery manufacturer’s instructions.

• Never throw a battery into a fire. There may be danger of an explosion.

• If the battery is dead or if you will not be using the remote control for a long time, remove

the battery to prevent damage to the remote control from possible battery leakage.

Introduction12

Positioning your projector

Obtaining a preferred projected image size

The distance from the projector lens to the screen, the zoom setting (if available), and the video format each factors in the projected image size.

4:3 is the native aspect ratio of this projector. To be able to project a complete 16:9 (widescreen) aspect ratio image, the projector can resize and scale a widescreen image to the projector's native aspect width. This will result in a proportionally smaller height equivalent to 75% of the projector's native aspect height.

4:3 aspect image in a 4:3

aspect display area

Thus, a 16:9 aspect image will not utilize 25% of the height of a 4:3 aspect image displayed by this projector. This will be seen as darkened (unlit) bars along the top and bottom (vertical 12.5% height respectively) of the 4:3 projection display area whenever displaying a scaled 16:9 aspect image in the vertical center of the 4:3 projection display area.

The projector should always be placed horizontally level (like flat on a table), and positioned directly perpendicular (90° right-angle square) to the horizontal center of the screen. This prevents image distortion caused by angled projections (or projecting onto angled surfaces).

The modern digital projector does not project directly forward (like older style reel-to-reel film projectors did). Instead, digital projectors are designed to project at a slightly upward angle above the horizontal plane of the projector. This is so that they can be readily placed on a table and will project forward and upwards onto a screen positioned so that the bottom edge of the screen is above the level of the table (and everyone in the room can see the screen).

If the projector is mounted on a ceiling, it must be mounted upside-down so that it projects at a slightly downward angle.

You can see from the diagram on page 14, that this type of projection causes the bottom edge of the projected image to be vertically offset from the horizontal plane of the projector. When ceiling mounted, this refers to the top edge of the projected image.

If the projector is positioned further away from the screen, the projected image size increases, and the vertical offset also increases proportionately.

When determining the position of the screen and projector, you will need to account for both the projected image size and the vertical offset dimension, which are directly proportional to the projection distance.

BenQ has provided a table of 4:3-aspect-ratio screen sizes to assist you in determining the ideal location for your projector. Refer to "Projection dimensions" on page 14 depending on the projector you are using. There are two dimensions to consider, the perpendicular horizontal distance from the center of the screen (projection distance), and the vertical offset height of the projector from the horizontal edge of the screen (offset).

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.

Connection

When connecting a signal source to the projector, be sure to:

1. Turn all equipment off before making any connections.

2. Use the correct signal cables for each source.

3. Ensure the cables are firmly inserted.

In the connections shown below, some cables may not be included with the projector (see

"Shipping contents" on page 8). They are commercially available from electronics stores.

Connecting a computer

The projector provides a VGA input socket that allows you to connect it to both IBM® compatibles and Macintosh® computers. A Mac adapter is needed if you are connecting legacy version Macintosh computers.

To connect the projector to a notebook or desktop computer:

1. Take the supplied multi-input cable and connect one end to the D-Sub output socket of the computer.

2. Connect the other end of the multi-input cable to the multi-input socket on the projector.

3. If you wish to make use of the projector speaker, take a suitable audio cable and connect one end of the cable to the audio output socket of the computer, and the other end to the audio input sockets of the multi-input cable.

The final connection path should be like that shown in the following diagram:

Notebook or desktop computer

Multi-input cable

Audio cable

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.

Connection 15

Connecting Video source devices

You can connect your projector to various Video source devices that provide any one of the following output sockets:

• Component Video

•Video (composite)

You need only connect the projector to a Video source device using just one of the above 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:

Best video quality

The best available video connection method is Component Video (not to be confused with composite Video). Digital TV tuner and DVD players output Component Video natively, so if available on your devices, this should be your connection method of choice in preference to (composite) Video.

See "Connecting a Component Video source device" on page 17 for how to connect the projector to a component video device.

Least video quality

Composite Video is an analog video and will result in a perfectly acceptable, but less than optimal result from your projector, being the least video quality of the available methods described here.

See "Connecting a composite Video source device" on page 18 for how to connect the projector to a composite Video device.

Connection16

Connecting a Component Video source device

Examine your Video source device to determine if it has a set of unused Component Video output sockets available:

• If so, you can continue with this procedure.

• If not, you will need to reassess which method you can use to connect to the device.

To connect the projector to a Component Video source device:

1. Take a Component Video to VGA (D-Sub) adaptor cable and connect the end with 3 RCA type connectors to the Component Video output sockets of the Video source device. Match the color of the plugs to the color of the sockets; green to green, blue to blue, and red to red.

2. Connect the other end of the Component Video to VGA (D-Sub) adaptor cable (with a D-Sub type connector) to the multi-input cable.

3. Connect the multi-input cable to the multi-input socket on the projector.

4. If you wish to make use of the projector speaker, take a suitable audio cable and connect one end of the cable to the audio output sockets of the Video source device, and the other end to the audio input sockets of the multi-input cable.

The final connection path should be like that shown in the following diagram:

Component Video to

Audio cable

• 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.

• When AUDIO OUT is connected with the earphone or external speaker, the sound will not

come out from the projector speaker.

• No sound will come out from the speaker or AUDIO OUT if video signals are not input.

Besides, the sound cannot be adjusted either.
