FOREWORD
A Word to the Owner of the DFF3
Congratulations on your choice of the FURUNO DFF3 Network Sounder. We are confident you
will see why the FURUNO name has become synonymous with quality and reliability.
For 60 years FURUNO Electric Company has enjoyed an enviable reputation for quality marine
electronics equipment. This dedication to excellence is furthered by our extensive global network
of agents and dealers.
This equipment is designed and constructed to meet the rigorous demands of the marine environ-
ment. However, no machine can perform its intended function unless operated and maintained
properly. Please carefully read and follow the recommended procedures for operation and main-
tenance.
Thank you for considering and purchasing FURUNO.
Features
The DFF3 network sounder is a dual frequency echo sounder designed for use with the FURUNO
NavNet/NavNet vx2/NavNet 3D series. The DFF3 feeds data about underwater conditions via a
LAN.
A few of the features are
• FURUNO Free Synthesizer (FFS) transceiver design allows use of user-selectable operating
frequencies (28 - 200 kHz).
• Automatic operation selects correct range and gain to show fish echoes and bottom in both
shallow and deep waters.
• Improved discrimination of near-surface fish by eliminating the transmission line.
• Heaving compensation* stabilizes the picture against ship’s pitching and rolling.
* Requires NavNet 3D display device and Satellite Compass SC-30, heading data fed in NMEA
®
2000 format.
®
• ACCU-FISH feature estimates length and depth of individual fish.
(Transducer 50/200-1T only for use with NavNet 3D.)
• 1/2/3 kW output
Note: The terms “NavNet” and “Navnet 3D” refer to the models listed below.

Network Sounder
The network sounder can be installed on a desktop, deck or on a bulkhead. When selecting a
mounting location for the network sounder, keep the following in mind:
• The temperature and humidity at the mounting site should be moderate and stable.
• Locate the unit away from exhaust pipes and vents.
• The mounting location should be well ventilated.
• Mount the unit where shock and vibration are minimal.
• Keep the unit away from electromagnetic field-generating equipment such as motors and gen-
erators.
• Leave slack in cables for maintenance and servicing ease.

1. MOUNTING
• A magnetic compass will be affected if the network sounder is placed too close to it. Observe
the compass safe distances noted in the safety instructions to prevent disturbance to the mag-
netic compass.
Fasten the network sounder to the mounting location with four self-tapping screws (5×20), refer-
ring to the outline drawing at the back of this manual for mounting dimensions.
1.3
Transducer
The performance of the echo sounder largely depends upon the transducer position. Select a
place least affected by air bubbles since turbulence blocks the sounding path. Further, select a
place least influenced by engine noise. It is known that air bubbles are fewest at the place where
the bow first falls and the next wave rises, at usual cruising speed.
Note: The face of the transducer must be facing the sea bottom in normal cruising trim of the boat.
1.4
Optional Speed/Temperature Sensors
ST-02MSB, ST-02PSB
1.4.1
Mounting considerations
Select a suitable mounting location considering the following points:
• Select a mid-boat flat position. The sensor does not have to be installed perfectly perpendicular.
However, the sensor must not be damaged in dry-docking operation.
• Select a place apart from equipment generating heat.
• Select a place in the forward direction viewing from the drain hole, to allow for circulation of cool-
ing water.
• Select a place free from vibration.
• Do not install near the transducer of an echo sounder, to prevent interference to the echo
sounder.

Mounting procedure
1. Dry dock the boat.
2. Make a hole of approx. 51 mm in diameter in the

TD-ID transducer (Airmar make transducer)
The TD-ID type transducer can be connected to this equipment. However, note the following lim-
itations:
• TD-ID transducer cannot be used with NavNet, NavNet vx2.
• TD-ID transducer cannot be used with non-TD-ID transducer.
• Connect single TD-ID transducer to low frequency WAGO connector, regardless of actual fre-
quency.
Cable fabrication
Fabricate the transducer cable as shown below. Separate the transducer cable well away from
other electric cables to prevent interference to the sounder. This is especially important in the case
of power cables from televisions and monitors.

4.2
Replacing the Fuse
The 5A fuse (Type: FGBO-A 125V 5A PBF, Code No. 000-155-853-10) in the snap-in fuse holder
on the power cable protects the equipment from equipment fault and reverse polarity of the ship's
mains. If the equipment cannot be powered, the fuse may have blown. Find out the cause for
blown fuse before replacing it. If the fuse blows again after replacement, contact a FURUNO agent
or dealer for advice.
WARNING
Use the proper fuse.
Use of a wrong fuse can damage the equip-
ment and cause fire.
4.3
Restoring Default Settings
This procedure restores all default sounder settings on the NavNet, NavNet 3D. You can restore
all default settings or restore those other than transducer and LAN. This procedure should only be
performed by a suitably qualified FURUNO technician.
1. Disconnect the power and LAN cables from the DFF3.
2. Turn on the #1 and #2 switches of the Mode switch. See section 3.2 for the location.
3. Turn on the #7 or #8 switch of the Mode switch as applicable.
#7: Restore default settings other than LAN and transducer.
#8: Restore all default settings. Use this when changing transducers.
4. Connect the power cable to the DFF3, and turn on the power at the ship’s switchboard.
5. The LED blinks (every four seconds) when default settings are completely restored.
