How to Set Up the Fish Finder
If you have a BBDS1 or DFF series fish finder connected to the same network, you
can set them up as shown in this section. If there is no networked fish finder in the
configuration, the settings outlined in this section are not required.
Note 1: Some menu items are restricted to certain external depth sounders; some
menu items may not be available with your networked fish finder.
Note 2: For DFF-3D setup instructions, see the DFF-3D operator's manual.
Note 3: In the following tables, the term "Shown with connection of..." means network
connection.
1. Tap the [FURUNO] icon to show the home screen and display mode settings.
2. Tap [Settings], then tap [Fish Finder]
3. Tap [User Settings]. [Fish Finder Source], then select fish finder source.
4. Tap [<] to go back one layer in the menu.

Set to change the TX center frequency and CHIRP width.
Please refer to the instruction manual for details.
Note: This menu is available when DFF3-UHD or TZT9F/
12F/16F/19F is connected.
When you turn the zero line (transmission line) rejection
on, the line is not shown, which allows you to see fish
echoes near the surface. The width of the line changes
with the transducer used and installation characteristics. If
the width of the line is 1.4 m or more, select [ON].
Note: If a DFF3 or DFF3-UHD is connected and this item
is set to [ON], set the range of rejection with [Zero Line
Range].
You can set the zero line removal range by turning on [Ze-
ro Line Rejection]. If the tail of the zero line is long, set a
large value. If the zero line still does not disappear, reduce
the transmission power. The default setting is 2.0
Note: Shown with connection of DFF3 or DFF3-UHD.
Set the distance between the transducer and the draft line
to show the distance from the sea surface.
Select [ON] if you use this equipment in salt water.
Select whether to transmit high and low frequencies simul-
taneously, or separately with a time delay. Normally, use
[Parallel], which transmits the frequencies simultaneously.
If you encounter interference near the bottom, select [Se-
quential A] or [Sequential B] in order to suppress the inter-
ference.
Note: Shown with connection of DFF3-UHD.
