    							32Using the Projector
    Adjusting the Image Quality
    You may need to adjust the projector’s Tracking and Sync settings if 
    your computer image has any of these quality problems:
    Flashing or blurry image
    Vertical or horizontal stripes
    Only a portion of the image is displayed
    See Chapter 3 for instructions on adjusting these settings in the 
    projector’s Video menu.
    Using the Remote Control
    The remote control lets you access projector features from anywhere 
    in the room—up to 32 feet away. You must also be within a 30° 
    horizontal and a 15° vertical angle of the infrared receiver on the front 
    of the projector.
    You can use the remote control to turn the projector on and off, zoom 
    the image, display the projector menus, and other uses. If you 
    connected a mouse cable to the projector, you can also use the remote 
    control as a wireless mouse to run your presentation. See page 34 for 
    instructions.
    Installing the Remote Control Batteries
    The remote control operates the projector and lets you access its setup 
    menus. You can also use it as a wireless mouse. 
    Follow these steps to install the 
    batteries:
    1. Press the tab to release the battery 
    cover and lift it up to remove it.
    note
    You can also increase 
    computer image clarity by 
    pressing the 
    Auto button on 
    the remote control to optimize 
    the tracking, sync, and 
    position settings. Turn off 
    E-Zoom and A/VMute before 
    using the 
    Auto button; see 
    page 30 and page 36.
    infrared receiver 
    for remote control
    note
    You can aim the remote 
    control at your projection 
    screen and reflect the signal 
    back into the sensor on the 
    front of the projector, but this 
    shortens the operating 
    distance of the remote 
    control. 
    						
    							Using the Projector33
    2. Insert the two AA batteries 
    included with the projector 
    as shown.
    3. Replace the battery cover.
    Operating the Projector with the Remote 
    Control
    1. Push up the R/C switch on the side of the remote control to turn 
    it on.
    2. Point the remote at the front of the projector or at the screen. 
    3. Press the button for the function you want to use. The light next 
    to the 
    Power button on the remote control flashes briefly. (If 
    it doesn’t flash, you may have inserted the batteries incorrectly or 
    need to change the batteries; see page 32 for instructions.)
    The projector may not respond to remote control commands in these 
    conditions:
    You are too far away or not within a 30° horizontal or 15° vertical 
    angle of the projector’s sensor
    The R/C switch on the right side of the remote control is in the 
    OFF position (the remote control is turned off)
    Batteries are weak
    Bright ambient light, fluorescent light, or direct sunlight is 
    shining into the remote control sensor
    Equipment emitting infrared energy (such as a radiant room 
    heater) is nearby and interfering with the sensor
    caution
    When replacing batteries, 
    take the following 
    precautions:
    Replace batteries as soon 
    as they run out. 
    Do not mix old and new 
    batteries. 
    If the batteries leak, wipe 
    away battery fluid with a 
    soft cloth. If fluid gets on 
    your hands, wash them 
    immediately.
    Remove batteries if you 
    will not be using the 
    remote for a long period 
    of time.

    							34Using the Projector
    Using the Remote Control as a Wireless Mouse 
    Using the remote control as a wireless mouse gives you more 
    flexibility; you don’t need to stay near your computer or the projector 
    to run your presentation.
    To use the remote control as a mouse, you must first connect a mouse 
    cable between your computer and the projector. See Chapter 1 for 
    instructions.
    Follow these instructions to use your remote control as a wireless 
    mouse:
    Aim the remote at the screen or at the receiver on the front of the 
    projector. To move the mouse pointer on the screen, press the 
    edges of the 
    Enter button with your thumb, as you would to 
    move a trackball.
    To click, press down on the center of the Enter button. To 
    double-click, press down twice on the 
    Enter button.
    To click and drag, press down on the Enter button and then tilt it 
    in the direction you want to drag.
    To right-click, press the Esc button.
    To change slides in a PowerPoint® presentation (in Slide Show 
    mode), press down on the 
    Enter button.
    note
    When you connect the mouse 
    cable, your computer mouse is 
    disabled and you can’t use 
    another external mouse with 
    your desktop. However, you 
    may still be able to use the 
    built-in mouse pointer on 
    your laptop.
    Press center 
    to left-click
    Press 
    here to 
    right-click Press edges 
    to move the 
    pointer
    note
    If you swapped the mouse 
    button functions on your 
    computer mouse, the 
    Enter 
    and 
    Esc buttons on the 
    remote control also swap 
    functions. 
    						
    							Using the Projector35
    Controlling Audio and Video
    While giving your presentation, you may want to switch between 
    picture sources, temporarily turn off or freeze the picture, or adjust the 
    volume. 
    Make sure you’ve first set up your projector and connected your audio 
    or video source as described in Chapter 1.
    Switching Between Picture Sources 
    You can connect the projector simultaneously to one computer source 
    and one video source. Then you can use the buttons on the projector 
    or remote control to switch between them.

    computer, S-video, and composite video sources. 
    Press the Computer, Video, or S-Video button on the remote 
    control to select the source you want to use. 
    After you select a source, the screen goes dark for a moment before the 
    image appears.
    Freezing the Picture
    You can use the remote control to freeze the current picture on the 
    screen.
    Press the Freeze button to freeze the current image on the screen. 
    The sound will continue. 
    Press the Freeze button again to re-start it.
