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 transmitting
antenna at a close distance.
Distances at which RF radiation levels of 100 and 10 W/m
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.

ELECTRICAL
SHOCK
HAZARD
Construct a suitable service platform
from which to install the antenna unit.
Serious injury or death can result if someone falls from the radar antenna mast.
Only qualified personnel
should work inside the
equipment.
Wear a safety belt and hard
hat when working on the
antenna unit.
Serious injury or death can
result if someone falls from
the radar antenna mast.
Be sure that the power supply is
compatible with the voltage rating of
the equipment.
Connection of an incorrect power supply
can cause fire or equipment damage. The
voltage rating of the equipment appears
on the label above the power connector.
Use only the specified power cable.
Fire or equipment damage can result if a
different cable is used.
CAUTION
Ground the equipment to
prevent electrical shock and
mutual interference.
Turn off the power at the mains switchboard before beginning the installation.
Fire, electrical shock or serious injury can
result if the power is left on or is applied
while the equipment is being installed.
Turn off the radar power
switch before servicing the
antenna unit. Post a warning sign near the switch
indicating it should not be
turned on while the antenna
unit is being serviced.
Prevent the potential risk of
someone begin struck by the
rotating antenna and exposure to RF radiation hazard.
Observe the following compass safe
distances to prevent deviation of a

1. MOUNTING
1.1 Mounting Methods for Antenna Unit
•
The antenna unit is generally installed either on top of the wheelhouse or on
the radar mast on a suitable platf orm. Locate the antenna unit where there is a
good all-round view. Any obstruction will cause shadow and blind sectors.
A mast for instance, with a diameter considerably less than t he width of the
radiator, will cause only a small blind sector, but a horizontal spreader or
crosstrees in the same horizontal plane as the antenna unit would be a much
more serious obstruction; you would need to place the antenna unit well above
or below it.
•
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 fitt ing.
•
If you have a radio direction finder on your boat, locate its 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 el ectrical equipment. Also avoid
running the cable in parallel with power cables.
•
A magnetic compass will be affected if placed too close to the antenna unit.
Observe the following compass safe distances to prevent deviation of a
magnetic compass: Standard compass, 1.00 m , Steering compass, 0.75 m.
•
Do not paint the radiator aperture, to ensure proper emission of the radar
waves.
•
When this radar is to be installed on larger vessels, consider the following
points:
!
The signal cable run between the antenna and the display comes in lengths
of 10 m (standard), 15 m, 20 m and 30 m. Whatever length is used it must
be unbroken; namely, no splicing allowed.
!
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.
