note If a button is pressed for longer than 30 seconds, the remote control stops operating to conserve battery power. When you release the button, normal operation resumes. Using the remote control under bright fluorescent lamps or in direct sunlight may affect projector response. Using the Remote Control Make sure batteries are installed as described on page 82. Follow these tips for using the remote control: ■ Point the remote control at the front or back of the projector, or at the screen. ■ Stand within 19.7 feet (6 meters) of the projector. ■ Aim the remote control within 30° to the side of, or 15° above or below, the remote control receivers on the projector. Controlling the Picture and Sound You can use the remote control to temporarily turn off the picture and sound, freeze the action, zoom in on the picture, and adjust the volume. Turning Off the Picture and Sound Press the A/V Mute button on the remote control or close the A/V Mute slide on the projector to turn off the image and sound, and darken your screen. This is useful if you want to temporarily re-direct your audience's attention without the distraction of a bright screen.
