Wrong operation or maintenance can cancel the warranty or cause injury.
• Do not copy any part of this manual without written permission from FURUNO.
• If this manual is lost or worn, contact your dealer about replacement.
• The contents of this manual and equipment specifications can change without notice.
• The example screens (or illustrations) shown in this manual can be different from the
screens you see on your display. The screens you see depend on your system
configuration and equipment settings.
• Save this manual for future reference.
• Any modification of the equipment (including software) by persons not authorized by

How to discard this product
Discard this product according to local regulations for the disposal of industrial waste. For
disposal in the USA, see the homepage of the Electronics Industries Alliance
(http://www.eiae.org/) for the correct method of disposal.
How to discard a used battery
Some FURUNO products have a battery(ies). To see if your product has a battery, see the
chapter on Maintenance. Follow the instructions below if a battery is used. Tape the + and -
terminals of battery before disposal to prevent fire, heat generation caused by short circuit.
In the European Union
The crossed-out trash can symbol indicates that all types of
batteries must not be discarded in standard trash, or at a trash
site. Take the used batteries to a battery collection site
according to your national legislation and the Batteries Directive
2006/66/EU.
In the USA
The Mobius loop symbol (three chasing arrows) indicates that
Ni-Cd and lead-acid rechargeable batteries must be recycled.
Take the used batteries to a battery collection site according to
local laws.
In the other countries
There are no international standards for the battery recycle symbol. The number of symbols
can increase when the other countries make their own recycling symbols in the future.

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 level of 100 and 10 W/m2are 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 representive or dealer to provide this feature.

WARNING
ELECTRICAL SHOCK HAZARD
Do not open the equipment.
Only qualified personnel
should work inside the
equipment.
Turn off the radar power
switch before servicing the
antenna unit. Post a warn-
ing sign near the switch
indicating it should not be
turned on while the antenna
unit is being serviced.
Prevent the potential risk of
being struck by the rotating
antenna and exposure to
RF radiation hazard.
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.
Do not disassemble or modify the
equipment.
Fire, electrical shock or serious injury can
result.
Immediately turn off the power at the
ship's mains switchboard if water
leaks into the equipment or the equip-
ment is emitting smoke or fire.
Continued use can cause fatal damage to
the equipment.
WARNING
Use the proper fuse.
Use of a wrong fuse can result in damage
to the equipment or cause fire.
Keep heater away from equipment.
Heat can alter equipment shape and melt
the power cord, which can cause fire or
electrical shock.
Do not place liquid-filled containers
near the equipment.
Fire or electrical shock can result if a liquid
spills into the equipment.
Do not operate the equipment with wet
hands.
Electrical shock can result.
Before servicing the radar, turn off
the appropriate external breaker.
Power is not removed from the radar simply
by turning off its power switch.

SAFETY INSTRUCTIONS

WARNING
No one navigational aid should be relied
upon for the safety of vessel and crew.
The navigator has the responsibility to
check all aids available to confirm
position. Electronic aids are not
a substitute for basic navigational
principles and common sense.
• This ARP automatically tracks
automatically or manually acquired radar
targets and calculates their courses and
speeds, indicating them by vectors. Since
the data generated by the auto plotter
are based on what radar targets are
selected, the radar must always be
optimally tuned for use with the auto
plotter, to ensure required targets will not
be lost or unwanted targets such as sea
returns and noise will not be acquired
and tracked.
• A target does not always mean a land-
mass, reef, ships or other surface vessels
but can imply returns from sea surface
and clutter. As the level of clutter changes
with environment, the operator should
properly adjust the A/C SEA, A/C RAIN
and GAIN controls to be sure target
echoes are not eliminated from the
radar screen.
CAUTION
The plotting accuracy and response of
this ARP meets IMO standards.
Tracking accuracy is affected by the
following:
•Tracking accuracy is affected by course
change. One to two minutes is required to
restore vectors to full accuracy after an
abrupt course change. (The actual
amount depends on gyrocompass
specifications.)
•The amount of tracking delay is inversely
proportional to the relative speed of the
target. Delay is on the order of 15—30
seconds for high relative speed; 30—60
seconds for low relative speed.
The data generated by ARP, AIS and
video plotter are intended for
reference only.
Refer to official nautical charts for
detailed and up-to-date information.
WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.
WARNING LABEL
Warning labels are attached to the
equipment. Do not remove any label.
If a label is missing or damaged,
contact a FURUNO agent or dealer
about replacement.
WARNING
Radiation hazard. Only qualified
personnel should work inside scanner.
Confirm that TX has stopped before
opening scanner.
