To adjust the forward looking Range, use the Right side of
the NAV button to select the Forward Range adjustment
(a red box will indicate it is selected). To adjust the range
up or down, use the NAV button.
When finished, press the EXIT softkey or allow the menu

Press the button labeled GAIN to bring up the choices
available for adjusting the SE-200 s receiver GAIN. Press
the button below AUTO so that the word AUTO is shown
inside a red box if you would like the SE-200 to
automatically adjust its receiver gain for changing
buttons to
conditions. To manually adjust press the
NAV button to increase or decrease the receiver gain. Note
that the GAIN MENU shows a number which indicates the
relative gain level being used. When you choose to
manually adjust the GAIN, the SE-200 turns off the
AUTO mode and it will remain off until the AUTO soft
key is again selected. You can also turn off the AUTO
GAIN feature by pressing the AUTO softkey again. To
exit the GAIN MENU and save your adjustments simply
press the exit symbol or allow the menu to time-out
(approx. 6 seconds)
Important Note: One of the biggest problems encountered
with forward scanning sonars is too much gain - especially
in the vertical forward view. If there are no targets
directly in front of the boat, the natural tendency is to
continue to increase the gain which can result in a noisy
display and false targets. In general, if you can see the
bottom between 3 and 4 times the depth forward (for
example in 10 feet of water, seeing the bottom forward 30
to 40 feet) the gain is adequate. (On forward ranges below
200 feet, it's recommended to keep the gain below the
number 14.)

The SE-200 has a useful screen cursor feature that can
show the approximate depth and range from the vessel to
any target on a forward scanning display.
