To make the gain or sensitivity setting when the unit is using the
200 kHz frequency, press this Soft Key. Use the up- and down-

Range
The “Range” is the maximum depth that the unit will display. To adjust
the range setting, press either the top or the bottom of the Range button.
Figure 3-16 shows the Soft Keys which allow you to set the range.
Range Auto/Manual
When you first press the Range button, the Fishfinder asks you to
set the range manually. Use the upper or lower parts of the Range
button to decrease or increase the range. If the bottom rises or falls
when Manual Range is selected, the Fishfinder will not adjust for
this.
The Fishfinder can also be set to select the range by itself,
automatically. Use the Soft Key to select the Auto Range function.
The unit chooses the shallowest range which will still include the
bottom in the display. To go back to Manual Range, use the Soft
Key to make the selection, or press either side of the Range button.
Range Downlook
If you select Manual Range or press this Soft Key, the Fishfinder
allows you to choose the manual range setting you want. The
current range setting will be highlighted. To change the setting, use
the up- or down-controls on the Range button.
