This is what the Toolbar will look like in Playback Mode. This mode is accessible from the Playback
Setup screen by pressing the green Start button. After clicking Start button the data file will scroll to the
end of the file and stop.
Pause/Resume

stops playback and the control button changes to Resume. The Resume control button can then be pressed
to continue playing back the selected data.
Gain
This Gain option is also referred to as display gain. It increases the amplitude of your data by multiplying
every sample by a constant value. This will enhance weaker reflections, but those already strong
reflections may be over-gained (See Output Distance Mode above for screenshots and additional
information).
Zoom
This option allows you to modify the horizontal scale by zooming in or out by factors of ½x, 1x, 2x, 4x,
or 8x (See Output Distance Mode above for screenshots and additional information).
Cursor Dir
You can move a horizontal and vertical cursor
around the screen during data playback.
•
Press the Cursor Dir control button to
change the cursor to either Vert(ical) or
Horiz(ontal). Then use the Control Knob
to adjust its position.
•
Rotate the knob left (counter-clockwise)
to move vertical cursor to the left. Rotate
the knob right (clockwise) to move the
vertical cursor to the right.
•
Rotate the knob left (counter-clockwise)
to move the horizontal cursor down the
time range. Rotate the knob clockwise to
move the cursor up the time range.
•
To turn the Cursor off press the Cursor Dir control button until it says Off. The Cursor Dir needs
to be turned off in order to use the arrow keys for other functions.
Dielectric
You can adjust the Dielectric Constant during playback from a value of one (1) to eighty-one (81).
•
Changing the Dielectric Constant will change the vertical scale if it is displayed in depth based on
the Time Range selected during setup.
