1.2 Antenna Unit
1.2.1 Mounting
Install the antenna unit referring to the "INSTALLATION PROCEDURE" at end of
manual.
Mounting considerations
Select a mounting location, keeping in mind the following points:
• Select a location out of the radar and inmarsat beams. Those beams will obstruct
or prevent reception of the GPS satellite signal.
• The location should be well away from a VHF/UHF antenna. Harmonic waves from
a VHF/UHF antenna interfere with the GPS receiver.
• There should be no interfering objects within the line-of-sight to the satellites. An ob-
ject within line-of-sight to satellites, for example, a mast, may block reception or pro-
long acquisition time.
• Mount the antenna unit as high as possible to keep it free from interfering objects
and water spray. Freezing water can interrupt reception of the GPS satellite signal.
• If the antenna cable is to be passed through a hole in a bulkhead which is too small
to pass the connector, disassemble the connector with radio pincers and a monkey
wrench. After passing the cable through the hole, assemble the connector as below.

1.3 Installation of Transducers (Option)
This equipment can use thru-hull, transom or
inner hull mounted transducers. Select a
transducer mounting type according to the
ship’s type. The optional inner hull mounting
kit (type: 22S0191) is required for inner hull
mounting. For details about inner hull mount-
ing, see the installation instructions supplied
with the inner hull mounting kit.
Transducer mounting location
The performance of this fish finder is directly related to the mounting location of the
transducer. The installation should be planned in advance, keeping the length of the
transducer cable and the following factors in mind:
• Air bubbles and turbulence caused by movement of the boat seriously degrade the
sounding capability of the transducer. The transducer should, therefore, be located
in a position where water flow is the smoothest.
• Noise from the propellers adversely affects performance and the transducer should
not be mounted nearby. The lifting strakes are notorious for creating acoustic noise,
and these must be avoided by keeping the transducer inboard of them.
• The transducer must always remain submerged, even when the boat is rolling,
pitching or up on a plane at high speed.
• A practical choice would be somewhere between 1/3 and 1/2 of your boat's length
from the stern. For planing hulls, a practical location is generally rather far astern,
so that the transducer is always in water regardless of the planing attitude.

1.3.1 Thru-hull mount transducer
The thru-hull mount transducer provides the best performance of all, since the
transducer protrudes from the hull and the effect of air bubbles and turbulence near
the hull skin is reduced. If your boat has a keel, the transducer should be at least 30
cm away from it.
1. With the boat hauled out of the water, mark the location selected for mounting the
transducer on the bottom of the hull.
2. If the hull is not level within 15° in any direction, fairing blocks made out of teak
should be used between the transducer and hull, both inside and outside, to keep
the transducer face parallel with the water line. Fabricate the fairing block as
shown below and make the entire surface as smooth as possible to provide an
undisturbed flow of water around the transducer. The fairing block should be
smaller than the transducer itself to provide a channel to divert turbulent water
around the sides of the transducer rather than over its face.
3. Drill a hole just large enough to pass the threaded stuffing tube of the transducer
through the hull, making sure it is drilled vertically.
4. Apply a sufficient amount of high quality caulking compound to the top surface of
the transducer, around the threads of the stuffing tube and inside the mounting
hole (and fairing blocks if used) to ensure watertight mounting.
5. Mount the transducer and fairing blocks and tighten the locknut. Be sure that the
transducer is properly oriented and its working face is parallel to the waterline.
The wood block will swell when the boat is placed in the water. It is suggested that
the nut be tightened lightly at installation and re-tightened several days after the
boat has been launched.
Note: Do not over-stress the stuffing tube and locknut through excessive tightening
(maximum torque: 39 N•m), the plastic screw may damaged.
Transducer preparation
Before putting your boat in water, wipe the face of the transducer thoroughly with a
detergent liquid soap. This will lessen the time necessary for the transducer to have

good contact with the water. Otherwise the time required for complete "saturation" will
be lengthened and performance will be reduced.
Note: DO NOT paint the transducer. Performance will be affected.
1.3.2 Transom mount transducer
The transom mount transducer is very commonly employed, usually on relatively
small outboard boats. Do not use this method on an inboard motor boat because tur-
bulence is created by the propeller ahead of the transducer.
A suitable mounting location is at least 50 cm away from the engine and where the
water flow is smooth.
Installation for flat hulls
When the deadrise angle is less than 10°, install the transducer parallel with hull.
1. Drill four pilot holes for self-tapping screw (5×20) in the mounting location.
2. Coat the threads of the self-tapping screws (5x14) for the transducer with marine
sealant for waterproofing. Attach the transducer to the mounting location with the
self-tapping screws.
3. Adjust the transducer position so the transducer faces right to the bottom. If
necessary, to improve water flow and minimize air bubbles staying on the
transducer face, incline the transducer about 5° at the rear. This may require a
certain amount of experimentation for fine tuning at high cruising speeds.

4. Tape the location shown in the figure at step 3, then fill the gap between the
wedge front of the transducer and transom with epoxy material to eliminate any
air spaces.
5. After the epoxy hardens, remove the tape.
Installation for deep-V hulls
This method is employed on deep-V hulls and provides good performance because
the effects of air bubbles are minimal. Install the transducer parallel with water surface;
not flush with hull (Do not install the transducer parallel with hull). If the boat is placed
on a trailer care must be taken not to damage the transducer when the boat is hauled
out of the water and put on the trailer.
1.3.3 Inside hull mount
The transducer may also be installed inside the hull on FRP boats. However, this
installation method affects the ability to detect the bottom, fish and other objects
because the ultrasound pulse is weakened when it passes through the hull.
Necessary tools
The following tools are required:
• Sandpaper (#100)
• Marine sealant
• Water-filled plastic bag
Remarks on installation
• Do the installation with the ship moored at a dock, etc. The water depth should be
6.5 to 32 feet (2 to 10 meters).
• Install the transducer on the hull plate in the engine room.
• Turn off the engine while installing the equipment.
• Do not power the unit with the transducer in the air, to prevent damage to the
transducer.
• Do not use this method on a double layer hull.

NOTICE
This mounting method should not be used to mount the transducer
that supports the ACCU-FISH

and bottom discrimination display,
since performance is greatly degraded.

Mounting location
Select 2-3 locations considering the four points mentioned below.
• Mount the transducer at a location 1/2 to 1/3 of the length of your boat from the
stern.
• The mounting location is between 15 to 50 cm from the centerline of the hull.
• Do not place the transducer over hull struts or ribs which run under the hull.
• Avoid a location where the rising angle of the hull exceeds 15°, to minimize the ef-
fect of the boat's rolling.
Deciding the mounting location
The attenuation of the ultrasound pulse varies with the thickness of the hull. Select a
location where attenuation is the lowest. Decide the most suitable site from the loca-
tions selected.
1. Put the transducer into water-filled plastic bag.
Press the transducer against the chosen site.
2. Press /BRILL key to turn the power on.
3. Select the transducer on the menu, referring
section 3.2.1.
See page 3-1 for how to use the menu.
4. Press the MENU key to go back to the [ECHO
SOUNDER INITIAL SETTING] menu.
5. Select [1. ECHO SOUNDER SYSTEM SETTING] on the [ECHO SOUNDER INI-
TIAL SETTING] menu.
The [ECHO SOUNDER SYSTEM SETTING] menu has two pages. When the
page 2 is displayed, press the 1key to open page 1.

6. Select [TRANSMISSION OUTPUT].
7. Press the appropriate numeric key to set the transmission power to a level of “02”.
8. Press the MENU key several times or press the DISP key to close the menu.
9. Press the DISP key several times to show the echo sounder display.
Check if the bottom echo appears on the right side of the screen, in the display
area. If no bottom echo appears, repeat the procedure unit a suitable location is
found.
10. Turn the power off and remove the transducer from the plastic bag after deciding
the mounting location.
Attaching the transducer
1. Wipe the face of transducer with a cloth to remove water and any foreign material.
Lightly roughen the face with #100 sandpaper. Also, use the sandpaper to rough-
en the inside of the hull where the transducer is to be mounted.
2. Dry the face of the transducer and the hull,
then coat the transducer face and mount-
ing location with marine sealant. Harden-
ing begins in approx. 15 to 20 minutes so
do this step without delay.
3. Attach the transducer to the hull.
Press the transducer firmly down on the
hull and gently twist it back and forth to
remove any air which may be trapped in
the marine sealant.
4. Support the transducer with a piece of
wood to keep it in place while the sealant is
drying. It takes 24 to 72 hours to harden
completely.
5. Turn the power on and change the menu
setting as shown below.

1.3.4 Triducer
Thru-hull mount triducer
The optional triducer 525STID-MSD is designed for thru-hull mounting. See
section 1.3.1 for how to install the 525STID-MSD.
Transom mount triducer
Mounting location
The optional transom mount triducer 525STID-PWD can be installed to the inboard or
outboard boats. To ensure the best performance, the sensor must be submerged in
aeration-free and turbulence-free water.
Mount the sensor close to the centerline of your boat. On slower heavier displacement
hulls, positioning it farther from the centerline is acceptable. Mount on the starboard
side at least 75 mm beyond the swing radius of the propeller, as shown in the following
figure.
