16. Do not step on the projector or place 18. any objects upon it. Besides probable physical damage to the projector, doing so may result in accidents and possible injury. This product is capable of displaying inverted pictures for ceiling mount installation.
Use only BenQ's Ceiling Mount Kit for mounting the projector and ensure it is securely installed.
Do not place liquids near or on the projector. Liquids spilled into the 19. projector may cause it to fail. If the projector does become wet, disconnect it from the power supply's wall socket and call BenQ to have the projector serviced.
When the projector is under operation, you may sense some heated air and odor from its ventilation grill. It is a normal phenomenon and not a product defect.
Safety instructions for ceiling mounting of 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 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. Important safety instructions 7

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 in the Advanced > Mirror 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 in the Advanced > Mirror 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 in the Advanced > Mirror 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 projector
Obtaining a preferred projected picture size
The distance from the projector lens to the screen, and the video format each factors in the projected picture size. The native resolution of the projector is 800 x 600 pixels, which is a 4 to 3 aspect ratio (expressed as 4:3). To be able to project a complete 16:9 (widescreen) aspect ratio picture, the projector can resize and scale a widescreen picture 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 picture in a 4:3 aspect display area
16:9 aspect picture scaled to a 4:3 aspect display area
Thus, a 16:9 aspect picture will not utilize 25% of the height of a 4:3 aspect picture 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 picture in the vertical center of the 4:3 projection display area. When determining the position of your projector, you should consider its intended use and input signal aspect ratios. All inputs (other than composite Video being fed a 16:9 aspect signal) will display in a 4:3 aspect ratio (and will require an additional 33% display height than that of the scaled 16:9 aspect picture projection area).

Do not select a permanent projector position based upon a 16:9 projection if you will ever need to select an input (other than composite Video being fed a 16:9 aspect signal).
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 picture 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 16, that this type of projection causes the bottom edge of the projected picture to be vertically offset from the horizontal plane of the projector. When ceiling mounted, this refers to the top edge of the projected picture. If the projector is positioned further away from the screen, the projected picture 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 picture 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. There are two dimensions to consider, the perpendicular 14 Positioning your projector
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
Select your screen size. Refer to the table and find the closest match to your screen size in the left columns labelled "4:3 Screen Diagonal". Using this value, look across this row to the right to find the corresponding average distance from screen value in the column labelled "Recommended projection distance from screen in mm". This is the projection distance. 3. 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. 4. 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 2 above, and offset by the value determined in step 3 above. For example, if you are using a 120 inch screen, the recommended projection distance is 4800 mm and with a vertical offset of 183 mm. If you place the projector in a different position (to that recommended), you will have to tilt it down or up to center the picture on the screen. In these situations, some picture distortion will occur. Use the Keystone function to correct the distortion. See "Correcting keystone" on page 25 for details. 1. 2.

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 the (optional accessory) 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 D-SUB socket on the projector. The final connection path should be like that shown in the following diagram: A/V device
Component Video to VGA (D-Sub) adaptor cable
If you connect the projector to a Digital TV (DTV) tuner, the following resolution is supported:
480i 576i 720p (50/ 60 Hz)
480p 576p 1080i (50/ 60 Hz)
Component Video is the only video output that delivers native 16:9 aspect ratio picture. If the selected video picture 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.
Connecting an S-Video or a composite Video source device
Examine your Video source device to determine if it has an unused S-Video or composite Video output socket 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.
If you have already made a Component Video connection between the projector and the video source device, you need not connect to this device again using an S-Video or composite Video connection as this makes an unnecessary second connection of poorer picture quality. You need only connect using a composite Video connection if both Component Video and SVideo are not supplied on the video source device (for example, with some analog video cameras). See "Connecting Video source devices" on page 18 for details.
To connect the projector to an S-Video/Video source device:
1. Take the (optional accessory) S-Video cable/Video cable and connect one end to the SVideo/Video output socket of the Video source device. 2. Connect the other end of the S-Video cable/Video Cable to the S-VIDEO/VIDEO socket on the projector. The final connection path should be like that shown in the following diagram: A/V device

Video cable

S-Video cable
If the selected video picture 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.

5. Operation

Start up
1. Plug the power cord into the projector and into a wall socket. Turn on the wall socket switch (where fitted). Check that the Power indicator on the projector lights orange after power has been applied.
The power cable used in the illustration may look different to the power cable type used in your region. Use only the power cable as supplied with the projector, and which is suitable for your region.
Remove the lens cap. If it is left on, it could become deformed due to the heat produced by the projector lamp.
Press and hold (for 2 seconds) Power on the projector or remote control to start the projector. 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 picture clarity.
If the projector is still hot from previous activity, it will run the cooling fan for approximately 110 seconds before energizing the lamp.
If you are prompted for a password, press the arrow buttons to enter a four digit password. See "Utilizing the password function" on page 22 for details. Switch on all of the connected equipment. The projector will start to search for input signals. The current input source being scanned displays in the center of the screen. If the projector doesnt detect a valid signal, the searching message will continue displaying until an input source 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 24 for details.

Operation

If a PC input is selected and the resolution is not 800 x 600, you will see a Resolution Reminder as below. For a better picture quality, please change the PCs resolution to 800 x 600 as requested.
Resolution Reminder Analog RGB 1024 x 768 60Hz Dynamic
In order to get better projection image quality, we suggest you to change your PC output resolution to SVGA (800 x 600).

The screen will be blank while AUTO is functioning.
Fine-tuning the picture clarity
If needed, sharpen the picture by rotating the focus ring.
If you are still not satisfied with the picture clarity, see "Sharpness" on page 35 to make further adjustment.
Selecting the aspect ratio
The 'aspect ratio' is the ratio of the picture width to the picture height. Most analog TV and computers are in 4:3 ratio, and digital TV and DVDs are usually in 16:9 ratio. With the advent of digital signal processing, digital display devices like this projector can dynamically stretch and scale the picture output to a different aspect than that of the picture input source. You can change the projected picture ratio (no matter what aspect the source is) by entering the Pro-Picture > Aspect Ratio menu. Select an aspect ratio to suit the format of the video signal and your display requirements. There are three aspect ratios available:
In the pictures below, the black portions are inactive areas and the white portions are active areas.
Native: The picture is projected at its original resolution, with no pixel conversion. For input signals with lower resolutions, the projected picture will display smaller than if resized to full screen. You could move the projector towards the screen to increase the picture size if necessary. You may also need to refocus the projector after moving the projector. 4:3: Scales a picture so that it is displayed in the center of the screen with a 4:3 aspect ratio. This is most suitable for 4:3 pictures like computer monitors, standard definition TV and 4:3 aspect DVD movies, as it displays them without aspect alteration. 16:9: Scales a picture so that it is displayed in the center of the screen with a 16:9 aspect ratio. This is most suitable for pictures which are already in a 16:9 aspect, like high definition TV, as it displays them without aspect alteration.
16:9 aspect ratio is only sourced through the Component Video input when being fed an appropriate 16:9 aspect signal. See "Connecting a Component Video source device" on page 19 and "Obtaining a preferred projected picture size" on page 14 for details.

Optimizing the picture

Selecting a picture mode
The projector is preset with several predefined picture modes so that you can choose one to suit your operating environment and input source picture type. To select a picture mode that suits your need, you can follow one of the following steps. Press MODE on the remote control or projector repeatedly until your desired mode is selected. Go to the Picture > Picture Left/ Right to select a desired mode. Mode menu and press
The preset picture modes are stored in the projector along with the current color temperature setting for each input. You can change the picture mode and color temperature settings for the currently active input, and your selection is automatically stored in the projector and associated with that input source. Each time you change the picture mode, the projector also changes the color temperature setting to the one which was last selected for that particular picture mode on that particular input. If you change the input source, the most recently used picture mode and color temperature for that input and resolution will be restored. The other picture properties such as brightness, color, contrast, tint, and sharpness, are not changed with a change in picture mode, however, are altered by a change in input. They remain constant and system wide, no matter what other picture properties are changed. See "Picture menu" on page 35 for details. The picture modes available for different types of signals are listed below.

Once BLANK is pressed, the projector enters Economic mode automatically. Do not block the projection lens from projecting as this could cause the blocking object to become heated and deformed or even cause a fire.

Freezing the picture

Press on the remote control to freeze the picture. An icon will display in the lower right corner of the screen. To release the function, press on the remote control, or SOURCE on the projector. Note that pressing SOURCE will also change the input source. Even if a picture is frozen on the screen, the pictures are running on the video or other device.
Operating in a high altitude environment
We recommend that you use the High Altitude Mode when your environment is between 1500 m3000 m above sea level, and temperature is between 0C35C.
Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and temperature is between 0C and 35C. The projector will be over cooled, if you turn the mode on under such condition.
To activate the High Altitude Mode, go to the Advanced > High Altitude Mode menu, select On by pressing Left/ Right on the projector or remote control. A confirmation message displays. Press Down.
We recommend you use the High Altitude Mode by selecting it whenever your environment is higher than 1500m. Confirm to turn High Altitude Mode on? Yes No
Next time you turn on the projector, it will show a message pictured below as a reminder during the start-up.
Current Status High Altitude Mode On
This mode is used for protecting projector from extreme environment and may cause higher fan speed.
Operation under "High Altitude Mode" may cause a higher decibel operating noise level because of increased fan speed necessary to improve overall system cooling and performance. If you use this projector under other extreme conditions excluding the above, it may display auto shut-down symptoms, which is designed to protect your projector from over-heating. In cases like this, you should switch to High Altitude mode to solve these symptoms. However, this is not to state that this projector can operate under any and all harsh or extreme conditions.
Shutting down the projector
1. 2. Press Power and a prompt message appears. Press
Are You Sure to Power Off? Press "Power" again to power off
Power a second time to turn the projector off. The Power indicator light flashes orange and the lamp shuts down, the fans continue to run for approximately 110 seconds to cool down the projector.
To protect the lamp, the projector will not respond to any commands during the cooling process.

If the projector will not be used for a long period of time, disconnect the power cord from the wall socket.
Do not unplug the power cord before the projector shutdown sequence is complete or during the 110second cooling down process. If the projector is not properly shut down, to protect the lamp, when you attempt to re-start the projector, the fans will run for a few minutes to cool down. Press Power again to start the projector after the fans stop and the Power indicator light turns orange.
