    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 
    projectors 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 manufacturers 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.

    Positioning your projector
    Choosing a location
    Your projector is designed to be installed in one of four possible installation locations: 
    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.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.

    							Positioning your projector 15
    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.
    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 
    projectors native aspect width. This will result in a proportionally smaller height equivalent 
    to 75% of the projectors native aspect height.
    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.
    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 image projection area).
    IMPORTANT: 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 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 17, 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. 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).4:3 aspect image in a 4:3 aspect display area16:9 aspect image scaled to a 4:3 aspect

    How to determine the position of the projector for a given 
    screen size
    1. Select your screen size.
    2. 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 
    Average. 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 average projection distance is 4667 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 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 33 for details.
    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. Measure the distance between the projector and where you want to position the 
    screen. This is the projection distance.
    2. 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.
    3. Using this value, look across that row to the left to find the corresponding screen 
    diagonal listed in that row. That is the projected image size of the projector at that 
    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 placement of the screen in relation to the 
    horizontal plane of the projector. 
    For example, if your measured projection distance was 4.5m (4500mm), the closest match in 
    the Average column is 4593 mm. Looking across this row shows that a 3000 mm (3.0 m) 
    screen is required. If you can only obtain imperial sized screens, the listed screen sizes on 
    either side of the 3.0 m screen are the 9 and 10 screens. 
    Checking the min and max projection distance values for these screen sizes, indicates that 
    the 4.5 m measured projection distance will fit the 10 size screen. The projector can be 
    adjusted (using the zoom control) to display on these different screen sizes at those 
    projection distances. Be aware that these different screens have different vertical offset 
    values.

    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 projectors optical characteristics. This will help you 
    determine the exact mounting position so that it best suits your installation location.
