Congratulations on your choice of the FURUNO DFF1-UHD Network Fish Finder. We are confi-
dent 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 DFF1-UHD is a dual frequency echo sounder designed for use with the NavNet TZtouch se-
ries. The DFF1-UHD feeds data about underwater conditions via a LAN connection.

CE declaration
With regards to CE declarations, please refer to our website (www.furuno.com) for further infor-
mation about RoHS conformity declarations.
• FURUNO TruEcho CHIRP
TM
fish finders provide very high definition images.
• High resolution display greatly reduces the possibility of missing a target.
• Noise-suppressing display for enhanced detection performance.
• Fish size shown for depths up to 200 m and bottom discrimination.
• Echoes are shown in high ultra definition, thus echoes are displayed differently from those present-
ed on the conventional fish finder.
• The interference rejector operates differently from the interference rejector on the conventional fish
finder, thus its effect on echoes is different.
• The transducer cannot be installed inside the vessel.
• Observe the following when using the ACCU-FISH
TM
feature:
• Use the feature where the depth is 2 - 200 m.
• The length of the TX pulse changes according to whether the feature is on or off. The appear-
ance of the display changes with the sensitivity.
• Observe the following when using the bottom discrimination display (hereafter referred to as BDD):
• Use the BDD under the following conditions:
- Depth: 5-200 m (16.4-656.2 ft)
- Speed: 10 knots or less”
• The BDD uses depth measured from the vessel’s draft in its analysis of bottom composition. Be
sure to set the draft at the NavNet equipment.
• The TX interval slows when the BDD is active.
• The BDD is inoperative if the transducer selection setting at the NavNet TZtouch is ”Manual”.
Measure for reduction of interference
If you receive interference from the fish finder/echo sounder of another vessel, switch to single fre-
quency operation and change the frequency and/or reduce the transmitting sound pressure level to
remove the interference.
