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.

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 and the enclosed ''User Information'' 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

PUSH

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.

• Operating the projector from the front

• Operating the projector from the rear

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 near the

floor 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 Mounting 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 Table Select this location with the projector placed near the

floor 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.

4. 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 Mounting Kit are required for this installation location.

Set Rear Ceiling 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.

Positioning your projector14

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.

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 diagrams on pages 17-20, 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 tables of 16:9-aspect-ratio and 4:3-aspect-ratio screen sizes to assist you in determining the ideal location for your projector. 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).

How to determine the position of the projector for a given screen size

1. Determine the aspect ratio of your screen, 16:9 or 4:3? If you have a 16:9 screen, refer to page 17 or 18. If you have a 4:3 screen, refer to page 19 or 20 depending on the projected picture aspect ratio you’ve got.

2. Select your screen size.

3. Refer to the table and find the closest match to your screen size in the left columns labelled "Screen Dimensions". Using this value, look across this row to the right to find the corresponding average distance from screen value in the column labelled

"Average". This is the projection distance.

4. On that same row, look across to the right column and make note of the "Vertical

Offset" value. This will determine the final vertical offset placement of the projector in

relation to the edge of the screen.

5. The recommended position for the projector is aligned perpendicular to the horizontal center of the screen, at the distance from the screen determined in step 3 above, and offset by the value determined in step 4 above.

For example, if you are using an 120-inch, 4:3-aspect-ratio screen and the projected picture is 16:10, please refer to Table B2 with a vertical offset of 61 mm.

on page 20. The average projection distance is 4180 mm and

Positioning your projector 15

How to determine the recommended screen size for a given distance

This method can be used for situations where you have purchased this projector and would like to know what screen size will fit in your room.

The maximum screen size is limited by the physical space available in your room.

1. Determine the aspect ratio of the screen you need, 16:9 or 4:3? If you need a 16:9 screen, refer to Table A1 to Table B1 ratio you’ve got.

2. Measure the distance between the projector and where you want to position the screen. This is the projection distance.

3. Refer to the table and find the closest match to your measurement in the average distance from screen column labelled "Average". Check that your measured distance is between the min and max distances listed on either side of the average distance value.

4. Using this value, look across that row to the left to find the corresponding "Screen

Dimensions" listed in that row. That is the projected image size of the projector at that

projection distance.

5. On that same row, look across to the right column and make note of the "Vertical

Offset" value. This will determine the final placement of the screen in relation to the

horizontal plane of the projector.

For example, if you need a 16:9 screen to project a 16:9 picture and your measured projection distance was 4.8 m (4800 mm), please refer to Table A1 match in the "Average" column is (about 3.0 m) screen is required.

If you place the projector in a different position (to that recommended), you will have to tilt it down or up to center the image on the screen. In these situations, some image distortion will occur. Use the Keystone function to correct the distortion. See "Correcting keystone" on

page 34 for details.

There is 3% tolerance among these numbers in Table A1, Table A2, Table B1, and Table B2 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 or monitor

Connecting a computer

The projector provides a VGA socket that allow you to connect it to both IBM® compatibles and Macintosh® computers. A Mac adapter (an optional accessory) is needed if you are connecting legacy version Macintosh computers.

Additionally, you can also connect the projector to a computer via the USB cable so you can perform paging operations of the application on the PC or notebook.

To connect the projector to a notebook or desktop computer

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

2. Connect the other end of the VGA cable to the D-SUB IN signal input socket on the projector.

3. If you wish to use the remote paging function, take a USB cable and connect the larger end to the USB port of the computer, and the smaller end to the USB socket on the projector. See "Remote paging operations" on page 42 for details.

4. If you wish to make use of the projector (mixed mono) speaker in your presentations, 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 socket of the projector.

Once connected, the audio can be controlled by the projector On-Screen Display (OSD) menus. See "Audio Settings" on page 53 for details.

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

i. VGA cable

ii. Audio cable

iii. USB 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.
