By pressing the DOWN button - once, the SE-200's
display will split and a conventional downlooking
display will appear at the left side of the screen as shown
on the right. The downlooking split screen mode will
work in either the vertical or horizontal display modes.
This down looking display is useful as it shows a history
of the bottom depth directly below the boat.
The vertical scale just to the right of the downlooking
display can be used to determine the depth below the
vessel. The current depth is also shown in the large
digits at the top left of the display. Adjust the RANGE
and GAIN for the best picture (see pages 9-10).
To see a full screen downlooking display, press the
DOWN button a second time. The display should look
similar to that shown on the right. This display shows
the recent history of the bottom echos. The most current
information is at the right of the screen.
Note: While in the Forward Horizontal / Down Split
mode, or if you select the Full Screen Down mode while
in the Horizontal mode, the Depth Range can be adjusted
independantly from the Forward Horizontal range.
Changing the Depth Range also changes the range of the
Depth Bar in the Full Screen Forward Horizontal view.
Downlooking Zoom
In the full screen downlooking display, you can ZOOM
into any 25% portion of the depth being displayed. For
example, if the downlooking depth range is 100 feet, then
the ZOOM function can be used to look at any 25% of
the depth - like 10 to 35 feet, 50 to 75 feet, etc.
To turn ON the ZOOM feature, press any of the five
softkeys to bring up the menu shown at right.
Then press the softkey for the ZOOM Symbol to bring
up a split screen zoom picture as shown at bottom right.
The normal depth display is on the left side, while the
larger right portion of the display shows the ZOOMED
picture. The NAV or UP/Down button can be used to
