Fish Finder Power Amplifier
Model DI-FFAMP
A Word to the Owner of the DI-FFAMP
Congraturations on your choice of the FURUNO DI-FFAMP Fish Finder Power Amplifier. The DI-
FFAMP is a power amplifier designed for use with the internal fish finder of the TZtouch3 (TZT12F/
16F/19F) multi function display. Please carefully read and follow the recommended procedures
for installation and maintenance. Thank you for considering and purchasing FURUNO.
Operational cautions
• A separate power supply is required. Take the power from the ship's mains via the ship's switchboard.
• The DI-FFAMP is not turned off when the multi function display is powered off. The power amp's standby
power is 6.2 W, so turn it off when it is not in use.
• Bottom Discrimination, RezBoost and ACCU-FISH are disabled when the power amp is in use.
• The amp can be used with two in-hull transducers, R599LM/LH and R111LH. Do not transmit with the
transducer out of water, to prevent damage to the transducer.
• Use the multi function display to change the program version of the power amp. Contact FURUNO for
information on how to upgrade program version.
Safety Instructions
The installer must read the safety instructions before attempting to install the equipment.

Installation
Select the mounting location considering the following points.
• Locate the unit away from areas subject to water splash.
• Select a location that is well ventilated.
• Observe the compass safe distances shown on page 1.
• Laeve the sufficient service clearance around the unit.
Procedure
1. Drill four pilot holes in the bulkhead (or tabletop) for the self-tapping screws.
2. Screw four self-tapping screws ( 5x20) into the pilot holes, leave 5 mm protruding.
3. Set unit onto the screws, then tightly fasten the screws to fix the unit in place.
NOTE: For on a bulkhead, the connectors must face downword.

Wiring
Wiring Outline
The figure below shows general connection for the DI-FFAMP. Refer to the interconnection dia-
gram for details.
Procedure
1. Unfasten six screws to remove the cover.
2. Fabricate the transducer cable(s) as shown below.
Fabricate the cables for both the high and low frequencies. For a CHIRP transducer, fabricate the ID
signal cores for both the high and low frequencies.
3. Unfasten the seal nut on the cable entry for transducer cable.
4. Pass the seal nut, claw and seal onto the transducer cable, in that order.
5. Push the seal assembly into the seal nut, then tighten the super gland.

6. Remove the WAGO connectors from PCB, then attach the transducer cable to the connector.
7. Clamp the braided shield with a cable clamp.
8. Attach the WAGO connector to the PCB.
9. Fasten the seal nut to fix the transducer cable.
The torque shall be 2.0 Nm and the gap between the seal nut and the super gland shall be approx. 3
mm.
10 . Fabricate the external KP signal cable as shown below. (core size 0.75 sq, outer dia 7.6 approx)
11. Pass the cable through the seal nut and seal assembly, like you did with the transducer cable.
12. Push the seal assembly into the seal nut, then tighten the super gland.
13. Tighten the seal nut to fasten the cable. The torque shall be 2.0 Nm and the gap between the seal nu t
and the super gland shall be approx. 3 mm.
14. Attach the WAGO connctors to the PCB.
15. Reattach the cover and fasten the screws to fix the cover.
Power cable (FRU-3P-FF-A002M-050C, 2m) and signal cables from Multi Function Diaplay (FRU-
F12F12-050C, 5m and FRU-F7F7-050C, 5m) should be connected with their attached connectors.
NOTE: Attach the EMC core to the power cable near the super
gland to prevent noise.
Attach the ground wire (IV-1.25sq, local supply) to the ground ter-
minal with a crimp-on lug (M3, local supply) to prevent interfer-
ence.

• Check the ship’s mains and check the switch board is
turned off.
• Check the fuse on the power cable. If the fuse has blown,
find the cause then replace it.
No echo appears but fixed
range scale appears.
• The sensor cable is disconnected or damaged. Check the
cable and reconnect or replace it as necessary.
Sensitivity is low. • Gain setting is too low. Raise the gain.
