WARNING
ELECTRICAL SHOCK HAZARD
Do not open the equipment.
Only qualified personnel
should work inside the
equipment.
WARNING
Turn off the power at the switchboard
before beginning the installation.
Fire or electrical shock can result if the
power is left on.
Do not install the display unit or
transceiver unit where it may get wet
from rain or water splash.
Water in the equipment can result in fire,
electrical shock or damage the equipment.
Be sure no water leaks in at the
transducer installation site.
Water leakage can sink the vessel.
Also confirm that the transducer will not
loosen by ship's vibration.
The installer of the equipment is solely
responsible for the proper installation of the
equipment. FURUNO will assume no
responsibility for any damage
associated with improper installation.
Install the specified transducer tank
in accordance with the installation
instructions. If a different tank is to be
installed the shipyard is solely respon-
sible for its installation, and it should
be installed so the tank doesn't strike
an object.
The tank or hull may be damaged if the
tank strikes an object.

WORKING WITH THE SONAR OIL
Precautions
Keep oil away from eyes. Wear protective
goggles when working with the oil. The oil
can cause inflammation of the eyes.
Do not touch the oil. Wear protective
gloves when working with the oil. The oil
can cause inflammation of the skin.
Do not ingest the oil. Diarrhea or vomiting
can result.
Keep the oil out of reach of children.
Emergency
If the oil enters eyes, flush with clean
water about 15 min. Consult a physician.
If the oil contacts skin, wash with soap
and water.
If the oil is ingested, see a physician
immediately.
Disposal of oil and its container
Dispose of oil and its container in
accordance with local regulations.
For further details, contact place of
purchase.
Storage
Seal container to keep out foreign
material. Store in dark place.
CAUTION
Keep hands away from the raise/lower
shaft of the hull unit when it is working.
Injury to hands may result if they become
caught in the shaft.
During sea trials, do not exceed 20
knots when operating the equipment
and do not exceed 15 knots when
raising or lowering the transducer.
The transducer shaft may become
damaged.
Do not turn on the equipment with the
transducer exposed to air as this may
damage the transducer.
Do not swing the soundome by holding
the transducer cable.
The cable and soundome may become
damaged.

1. MOUNTING
1.1 Display Unit, Control Unit
This searchlight sonar is available in two configurations: one with the FURUNO-supplied
display unit or one with no display unit and an interface unit (with which to connect a
monitor, locally supplied). For installation of the system which uses a locally supplied
monitor, see paragraph 1.1.3 on page 6 for monitor requirements and installation
information.
The control unit can be installed together with the display unit, or independently, using the
optional mounting kit. These units may be installed on a desktop or flush mounted in a
console.
1.1.1 General mounting considerations
• Keep the units out of direct sunlight.
• Select a location where the units can easily be operated while observing the fishing
ground or area surrounding the vessel.
• For maintenance and checking purposes, leave sufficient space at the sides and rear of
the units and leave slack in cable. (Refer to the outline drawing at the back of this manual
for recommended maintenance space.)
• A magnetic compass will be affected if the display unit (or control unit when it is installed
separately) is placed too close to the compass. Observe the following compass safe
distances to prevent deviation to the compass: Standard compass: 0.80 m, Steering
compass: 0.55 m.

1.1.3 System with locally supplied monitor
Monitor requirements
This system requires a standard VGA monitor, connected to the interface unit IF-8000.
Supply monitor and interconnection cable locally. A D-sub 15P connector is required for
connection to the DATA/VIDEO OUT port on the IF-8000. Use the three rows-type D-sub
connector; not the two rows-type.
YES NO
The monitor should satisfy the specifications shown below.
• VGA type
• ANALOG RGB 0.7 Vpp, positive polarity
• TLL level H, V, negative polarity
Mounting the control unit on a desktop
For the system which uses a locally supplied monitor, fix the control unit to the mounting
plate (supplied as accessories) as shown below. See the parts list FP06-01120 and outline
drawings at the back of this manual for details.
1. Fix the mounting plate to the mounting location with two tapping screws (5X20).
2. Fix the bracket to the control unit with two hex. screws (M4X12).
3. Insert screwdriver from the top of the mounting plate holes and then loosely fasten two
hex. screws (M4X12).
4. Attach the control unit to the mounting plate and then tightly fasten two hex. screws.
5. Attach two cosmetic caps to holes at the top of the mounting plate.

1.2 Transceiver Unit
1.2.1 General mounting considerations
• The mounting location should be well ventilated and dry.
• The unit can be mounted on a bulkhead or a desktop. For bulkhead mounting, be sure
the bulkhead is strong enough to support the weight of the unit under the vibration
normally experienced onboard the vessel. If necessary, reinforce the mounting location.
• Secure maintenance space for ease of maintenance and service, referring to the outline
drawing for recommended maintenance space.
• The maximum length of the cable between the transceiver unit and the raise/lower drive
assy. is 30 m.
• The maximum length of the cable between the transceiver unit and the display unit (or
interface) is 10 m.
• A magnetic compass will be affected if the transceiver unit is placed too close to the
compass. Observe the following compass safe distances to prevent deviation to the
compass: Standard compass: 0.60 m, Steering compass: 0.35 m.
1.2.2 Mounting procedure
The transceiver unit may be mounted a desktop or a bulkhead. Fasten the unit to the
mounting location with four tapping screws (5 mm diameter, local supply).

For bulkhead mounting:
1. Screw in upper tapping screws, leaving 5 mm gap between bottom of screw head and
bulkhead as shown right.
2. Set the unit to the tapping screws and tighten screws.
3. Screw in lower tapping screws.

1.3 Hull Unit
1.3.1 General handling considerations
CAUTION
Do not turn on the equipment with the
transducer exposed to air as this may
damage the transducer.
The soundome may be painted with antifouling paint to keep marine life of the transducer.
Use “Marine Star 20,” manufactured by Chugoku Marine Co., Ltd., or equivalent. Paint only
the portion below the sticker. Painting metal parts will cause corrosion.

1.3.2 Installation position considerations
Discussion and agreement are required with the dockyard and ship owner in deciding the
location for the hull unit. When deciding the location, take into account the following points:
• Select an area where propeller noise, cruising noise, bubbles and interference from
turbulence are minimal. Generally, the point at 1/3 to 1/2 of the ship’s length from the bow
or near the keel is the best. On-the-keel installation is advantageous for minimizing oil
consumption in comparison with of-the-keel. If the hull unit cannot be installed on the keel,
the center of the retraction tank should be within 1 m of the keel to prevent a rolling effect.
1/2 1/3 Within 1 m
• Select a place where interference from the transducers of other sounding equipment is
minimal. The hull unit should be at least 2.5 m away from the transducers of other
sounding equipment.
• An obstacle in the fore direction not only causes a shadow zone but also aerated water,
resulting in poor sonar performance. Be sure to locate the transducer well away from any
obstacle in the fore direction.
