SAFETY INSTRUCTIONS
WARNING
Radio Frequency Radiation
Hazard
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 trans-
mitting antenna at a close distance.
Distances at which RF radiation levels of
100 and 10 W/m
2
exist are given in the
table below.
Note: If the antenna unit is installed at a
close distance in front of the wheel house,
your administration may require halt of
transmission within a certain sector of
antenna revolution. This is possible–Ask
your FURUNO representative or dealer to
provide this feature.

1. MOUNTING
1.1 Antenna Unit
Mounting considerations
• The antenna unit is generally installed either on top of the wheelhouse, on the radar mast,
or on a suitable platform. Locate the antenna unit where there is a good all-round view.
• No funnel, mast or derrick should be within the vertical beamwidth of the antenna unit in
the bow direction, especially zero degrees ±5°, to prevent blind sectors and false echoes
on the radar picture.
• It is rarely possible to place the antenna unit 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.
• Locate a direction finder antenna clear of the antenna unit to prevent interference to the
direction finder. A separation of more than two meters is recommended.
• To lessen the chance of picking up electrical interference, avoid where possible routing
the signal cable near other onboard electrical equipment. Also avoid running the cable in
parallel with power cables.
• A magnetic compass will be affected if the antenna unit is placed too close to the
magnetic compass. Observe the compass safe distances on page ii to prevent deviation
of the magnetic compass.
• Do not paint the radiator aperture, to ensure proper emission of the radar waves.
• The signal cable run between the antenna and processor units is available in lengths of
15 m (standard), 30 m and 50 m. Whatever length is used it must be unbroken; namely,
no splicing allowed.
• The antenna base is made of cast aluminum. To prevent electrolytic corrosion of the
antenna base, use the seal washers and corrosion-proof rubber mat and ground the unit
with the ground wire (supplied).
• 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 antenna unit must not be
mounted where the temperature is more than 70°C.
• Leave sufficient space around the unit for maintenance and servicing. See the antenna
unit outline drawing for recommended maintenance space.

Installation precaution for S-band antenna unit
If an S-band antenna unit is mounted near the end of a platform to provide sufficient rotation
clearance for the radiator, the antenna unit, because of its weight, swings up and down by
ship’s vibration and rolling. This exerts excessive levels of stress at the base of the radiator,
which can damage the radiator. To prevent this, relocate the antenna unit, or if relocation is
not possible, reinforce the platform.
Mast for
DF, etc.
Mount the antenna unit
directly on the mast or on
the platform, as near as
possible to center of the
mast.

Fastening the antenna unit to the mounting platform
See the figure on the next page for antenna unit mounting.
1. Referring to the antenna outline drawing, drill eight fixing holes of 15 mm in diameter in
the radar mast platform or the deck.
• The diameter of the mast for fixing the antenna unit platform must be over 250 mm.
• The thickness of the antenna unit platform must be over 15 mm.
• The reinforcement rib must be installed diagonally as shown below.
Over 15mm
250mm diameter or more,
6 mm thick or more
Use two nuts.

2. Place the corrosion-proof rubber mat (supplied) on the mounting platform.
3. Hoist the antenna unit as shown on page 1-3 and place it on the rubber mat. Orient the
cable gland toward the ship’s stern (or port, starboard). Remove the lifting fixtures and
collars.
4. Fix the antenna base to the mounting platform with four M12X70 hex bolts, nuts,
washers and seal washers (supplied). For the unit with the performance monitor (PM),
orient the PM toward the ship’s stern.
5. Arrange the grounding terminal at the nearest grounding spot with the M6X25 hex bolt,
nut and washers. Then, fix a ground wire (RW-4747, 340 mm) to the terminal.
6. Connect the other end of the ground wire to the ground terminal of the antenna unit.

Mounting considerations
When selecting a mounting location, keep in mind the following points:
• Select a location where the display unit can be viewed conveniently and where the
screen can be viewed while facing towards the bow.
• Locate the unit out of direct sunlight and away from heat sources because of heat that
can build up inside the cabinet.
• Locate the equipment away from places subject to water splash and rain.
• Leave sufficient space on the sides and rear of the unit to facilitate maintenance.
• A magnetic compass will be affected if the monitor unit is placed too close to the
magnetic compass. Observe the compass safe distances on page ii to prevent deviation
of a magnetic compass.
Mounting procedure
Flush mounting
Follow the procedure below to mount the monitor unit in a console panel.

1.3 Power Supply Unit
The Power Supply Unit PSU-007 does not contain usual operating controls. Therefore, it
can be installed in any recessed place either in vertical or horizontal position. (For the
console mount display unit, the PSU-007 can be installed inside the console.) However,
select a dry and well-ventilated location and observe the compass safe distance to prevent
deviation of a magnetic compass. See page ii.
1. Open the cover of the power supply unit.
2. Fasten the unit to chosen location with four self-tapping screws 5x20.
3. After connecting cables, attach the cover.

1.4 Control Unit
The control unit may be mounted on a tabletop, with or without the KB fixing metal
(supplied), which mounts the control unit at an angle.
Mounting considerations
When selecting a mounting location, keep in mind the following points:
• Select a location where the control unit can be operated conveniently.
• Locate the unit away from heat sources because of heat that can build up inside the
cabinet.
• Locate the equipment away from places subject to water splash and rain.
• Determine the mounting location considering the length of the signal cable between the
control unit and the processor unit. (The signal cable comes in lengths of 10 m).
• A magnetic compass will be affected if the control unit is placed too close to the magnetic
compass. Observe the compass safe distances on page ii to prevent deviation of a
magnetic compass.
Fixing with KB fixing plate
1. Fix the KB fixing plate to the bottom of the control unit.
2. Attach cushions (three for RCU-014, two for RCU-015/016) to the bottom of the control
unit as shown below.
3. Fix it to a desired location with self-tapping screws (local supply).
