features. To playback a sample file follow the steps below.

sample file from the sample file stored on the hard disk. The default location of the sample files
is: C:\Program Files\JW Fishers\SCAN-650\Sample Data Files

single blue arrow pointing to the right. The saved file will begin to play.

6. Click the Rewind button on the toolbar on the left of the screen. The Rewind button is the double
blue arrowhead pointing to the left. The double blue arrowhead with the line in front is the Rewind

to any point on the recorded file. Click the Stop button when the file is rewound to the desired

target. Holding both the shift key and the mouse button down, move the mouse arrow to the other

eters were set when the file was originally recorded and can not be changed during playback
mode.
