DownScan image
When zooming in on a DownScan image, the sea floor will be kept near to bottom of the
screen, irrespective of whether it is in auto-range or manual range.
If the range is set considerably less than the actual depth, the unit will not be able to find
the bottom when zooming.
If the cursor is active, the unit will zoom in where the cursor is pointed.
SideScan image
Zooming on a SideScan image acts as for DownScan, except that it zooms on the surface
rather than trying to keep the sea floor in view.
When the cursor is active, it will zoom where the cursor is pointed.
Adjusting the color settings
Strong and weak echo signals have different colors to
indicate the different signal strengths. The colors used
depend on which palette you select.
The more you increase the Color setting, the more echoes
will be displayed in the color at the strong return end of the
scale.
Color is adjustable by tapping and a vertical dragging
movement or by using the OP40 rotary knob. When you
press the knob the color control image will expand and
display it's name in full. You can then adjust the value by
turning the knob. If no adjustments are made within 3
seconds the control will return to default size.

bottom of the screen (SideScan).
You can pan the image history by dragging up/down (SideScan) or left/right DownScan.
