Rewind Speeds

When you press Near (Rewind) or move the joystick left, the recorded video plays in reverse at 2x speed. Pressing Near again increases the speed at which the video plays in reverse. Figure E identifies the rewind progression (refer to Playback Speed on page 37 for an explanation of the abbreviations; negative values, such as -8x, indicate reverse playback.).

Using Digital Zoom

NOTE: This functionality applies to recorded video only.

During playback of recorded video, you can use the digital zoom feature to enlarge a portion of the video image. When digital zoom is enabled, a picture-in-picture frame opens on the monitor. The picture-in-picture frame displays the original recorded image and contains a square showing the portion of the image that is enlarged. The remaining monitor image displays the enlarged image.

1.Twist the joystick to the right and then return the joystick to the center position. Repeat this step to zoom in further.

2.To zoom out to a lower digital zoom magnification, twist the joystick to the left and then return the joystick to the center position. When you reach normal magnification, the picture-in-picture frame on the monitor disappears.

When digital zoom is active, move the joystick in any direction (up, down, left, or right) to move the square inside the picture-in-picture frame; this allows you to move the portion of the image covered in the zoomed view.

NOTE: When digital zoom is active, each joystick movement must be followed by a return to the center position.
