WARNING
The radar antenna emits electromagnetic radio frequency (RF)
energy which can be harmful, particularly to your eyes. Never
look directly into the antenna aperture from a close distance
while the radar is in operation or expose yourself to the
transmitting antenna at a close distance.
Distances at which RF radiation levels of 100, 50 and 10 W/m2exist
are given in the table below.
100 W/m210 W/m2
50 W/m2
N/A N/A 1.1 m
WARNING LABEL
A warning label is attached to the sensor. Do not remove the label.
If the label is missing or damaged, contact a FURUNO agent or dealer about
replacement.

1. INSTALLATION
1.1 Installation Considerations
General considerations
• The radar sensor has no power switch. Therefore, it is recommended that you con-
nect the sensor to a distribution switchboard with a switch for power control.
Sensor placement
• Install the radar sensor on the hardtop, radar arch or on a mast on an appropriate
platform. (For sailboats, a “radome mount” is optionally available for fixing the sen-
sor to a mast.) Place the sensor where there is a good all-round view with, as far as
possible, no part of the ship’s superstructure or rigging intercepting the scanning
beam. Any obstruction will cause shadow and blind sectors. A mast for instance,
with a diameter considerably less than the horizontal beam width of the radiator, will
cause only a small blind sector, but a horizontal spreader or cross trees in the same
horizontal plane as the radar sensor would be a much more serious obstruction; you
would need to place the radar sensor well above or below it. Be sure there are no
metallic objects near the antenna. See illustrations below for typical placement on
a sailboat and powerboat.
NOTICE
Do not apply paint, anti-corrosive sealant or contact
spray to coating or plastic parts of the equipment.
Those items contain organic solvents that can damage
coating and plastic parts, especially plastic connectors.

• It is rarely possible to place the radar sensor where a completely clear view in all
directions is available. Thus, you should determine the angular width and relative
bearing of any shadow sectors for their influence on the radar at the first opportunity
after fitting.
• In order to reduce the chance of picking up electrical interference, avoid where pos-
sible routing the power cable near other electrical equipment on-board. Also, avoid
running the cable in parallel with other power cables.
• Select a location that does not allow water to accumulate at the base of the sensor.
• A magnetic compass will be affected if the radar sensor is too close to the compass.
Observe the compass safe distances mentioned in the SAFETY INFORMATION to
prevent interference to a magnetic compass.
• Do not paint the radome to ensure proper emission of the radar waves.
• When this radar sensor is to be installed on a large vessel, consider the following
points:
• The length of the standard supply power/LAN cable is 1 m (from radome to the
connector).
• The power/LAN cable runs between the radar sensor and display and comes in
lengths of 10 m, 15 m, 20 m or 30 m. Select the length when purchasing.
• Deposits and fumes from a funnel or other exhaust vent can adversely affect the
aerial performance and hot gases may distort the radiator portion. The radar sen-
sor must not be mounted where the temperature is more than 55°C (131°F).
• The radar sensor should not be operated or stored in any position other than the
proper operational position (upright).
1.2 Installation of the Radar Sensor
Determine the suitability of the mounting location BEFORE permanently mounting the
sensor. Incoming and outgoing signals may overlap one another depending on the
shape of the vessel, preventing communication between the radar and display. Set the
sensor on the selected location and connect the sensor to the distribution switchboard
and display unit. Turn on the sensor and the display unit. Check that the picture is up-
dated with each sweep on the display unit. Some trial and error may be necessary to
find a suitable location.
Required tools for installation
Prepare the tools shown below.
• A wrench for M10 bolts
• An electric drill with I11 mm (0.43”) drill bit

Installation on a platform
Follow the instructions below to install the sensor on a platform.
Note: The outer diameter of the small flat washer is the same size as the bolt hole. If
the radome is put upside down with only the small flat washer and hex bolt in place,
the hex bolt and flat washer may protrude into the radome and damage the RT unit.
For this reason, DO NOT put the radome upside down when carrying the radome.
If it is necessary to transport the radome, be sure the large flat washers are in place
before transporting, to prevent damage to the RT unit.

1. Remove four each of hex bolts (M10u20), flat washers and spring washers pre-
attached to the bottom of the radar sensor.
2. Using the template supplied, construct a platform and drill mounting holes in the
platform to fasten the sensor. The holes must be parallel with the fore and aft line.
3. Put the radar sensor on the platform with the bow mark (U) on the sensor aligned
with the ship’s bow.
4. Use hex bolts (see the table on the next page for bolt length), flat washers and
spring washers (removed at the first step) to fasten the radar sensor to the plat-
form. The torque for the bolts is 19.6 to 24.5 N•m. Apply marine sealant (local sup-
ply) to the hex bolt.
Platform thickness and bolt to use
5. Connect the power/LAN cable pre-attached to the
radar sensor to the power/LAN cable. The connec-
tor pin assignment is as below.
Observe below guidelines for laying the power/LAN cable.
Guidelines for laying the power/LAN cable
• The connectors must not strike any part of the vessel by wind, etc.
• The load applied to the connectors must not be more than the power/LAN cable.
• If the cable is passed through a mast on a sailboat, be sure the cable does not
touch ropes (sheet, halyard, etc.).
• Do not fasten the cable to the hull.

• The cable must be fixed so no tension is applied to the connectors. To prevent
tension, create a loop in the cable close to the sensor and tie the loop with cable
ties, as in the figure below.
• Wrap the junction of the connectors with self-vulcanizing tape for waterproofing.
• Fasten the cable to the mast, etc. at the neck of each connector with a cable tie.
6. Connect the power/LAN cable to the power source and display unit.
Installation with the radome mount
The optional radome mount lets you fasten the radar sensor to a mast on a sailboat.
