Playing back frame-by-frame
You can easily play back a selected video at different speeds. This allows you to

playback control toolbar until the speed changes to single frame.
2. Click the Pause button to advance the video frame by frame.
• Using the front panel:
1. In playback mode press the up/down arrow buttons to scroll down and up
through the speed changes until single frame.
2. Press Enter to advance the video frame by frame.
3. Press the Playback button to continue playback at normal speed.
Digital zoom in playback
You can easily zoom in on an image during playback to see it in greater detail.
To digitally zoom-in during playback:

menu. The playback control toolbar disappears.

The image zooms in and the digital view window appears.
3. Left-click the mouse and drag the red square to the area of interest, or press
the arrow buttons on the front panel to position the red square. The selected
area is magnified. The size of the red square cannot be changed using the
