Operating instructions 5 Viewfinder displays When you press the shutter button halfway, displays indicating distance and symbols for "good picture" or "caution" appear in the viewfinder. When you see the green symbol press the shutter button the rest of the way to take the picture. When you hear a warning tone and see the flashing yellow caution symbol your subject is either too close, too far, or the flash is turned off. For example, the display shows the yellow symbol and the distance 1: • your subject is too close. Release the shutter button and stand at least 2 feet from your subject. If the display shows the yellow symbol and a distance from 16 to 20*: • your subject is beyond the flash range. Release the shutter button and position your subject within the 2 to 15 foot flash range. If the display shows the yellow symbol and a distance from 2 to 15: • your subject is within range, but the flash is off. Press the Auto reset button to turn the flash on. *When your subject is beyond 20 feet, the distance display is blank. Autofocus system When you press the shutter button, sonar waves (at frequencies beyond our range of hearing) are sent to the central part of the scene. A built-in computer measures the time it takes the sonar waves to reach the scene and the echo to return. This measurement is used to provide the correct lens setting. • Be sure the sonar waves have a clear path to your subject. If an object near the central part of the scene prevents the sonar waves from reaching your subject, the lens focuses on that object, causing your subject to be unsharp. • When photographing more than one person, focus and illumination are improved if everyone is at about the same distance from the camera. You can turn off the autofocus system to focus manually. See Manual focusing. Audio signals Your camera has three audio signals: a warning tone when the "caution" symbol appears in the viewfinder, beeps that signal the self-timer countdown, and chimes that tell you the film pack is empty.
