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.
Since 1948, 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 and Navnet TZtouch series. The DFF3 feeds data about under-
water conditions via a LAN.
• 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/TZtouch display device plus Satellite Compass SC-30.
• Approximate fish length calculation available with conenction of transducer 50/200-1T. (NavNet
3D and TZtouch only.)
• 1/2/3 kW output
Note: The terms “NavNet”, NavNet vx2”, “Navnet 3D” and “NavNet TZtouch” refer to the models

1.2 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.

• 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:
• Selecta mid-boat flat position. The sensor does nothavetobe installedperfectlyperpendicular.
However, the sensor must not be damaged in dry-docking operation.
• Select a place apart from equipment generating heat.
• Select aplace in the forward direction viewing from the drain hole, toallow 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.
1.4.2 Mounting procedure
1. Dry dock the boat.
2. Make a hole of approx. 51 mm in diameter in the
mounting location.
3. Unfasten locknut and remove the sensor section.
4. Apply high-grade sealant to the flange of the sen-
sor.
5. Pass the sensor casing through the hole.
6. Face the notch on the sensor toward boat's bow
and tighten the flange.
7. Set the sensor section to the sensor casing and
tighten the locknut.
8. Launch the boat and check for water leakage
around the sensor.

1.5 Optional Temperature Sensors
1.5.1 Transom mount temperature sensor T-02MTB
• Fix the cable at a convenient location with cable clamp.
• When the cable is led in through the transom board, make a hole of approx. 17 mm in diameter
to pass the connector. After passing the cable, fill the hole with a sealing compound.

1.5.2 Thru-hull temperature sensor T-02MSB, T-03MSB
Select a suitable mounting location considering the following points:
• Selecta mid-boat flat position. The sensor does nothavetobe installedperfectlyperpendicular.
However, the location should not be such that the transducer may be damaged when the boat
is dry-docked.
• Locate away from equipment which gives off heat.
• Locate away from drain pipes.
• Select a location where vibration is minimal.

2. WIRING
2.1 Wiring Outline
Connect the power cable, transducer cables, sensor cable, network cable and ground wire to their
respective locations on the network sounder. See the next page for how to connect the transducer
cables.
Ground
Connect a ground wire (IV-2 sq, local supply) between the
ground terminal and ship’s ground to prevent interference
to the sounder picture. Make the length of the wire as short
as possible. For FRP vessels, install a ground plate that
measures about 20 cm by 30 cm on the outside of the hull
bottom and connect the ground wire there.
