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(ies), see the
chapter on Maintenance. Follow the instructions below if a battery(ies) is used.

In the European Union

The crossed-out trash can symbol indicates that all types of batt eries
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.

Ni-Cd Pb

In the other countries

Cd

There are no international standards for the battery recycle symbol. The number of symbols can
increase when the other countries make their own recycle symbols in the future.

WARNING

Radio Frequency Radiation Hazard

The radar antenna sends the electromagnetic radio frequency (RF) energy. This
energy can be dangerous to you, especially your eyes. Do not look at the radiator or
near the antenna when the antenna is rotating.

2

The distances at which RF radiation levels of 100 W/m
are shown in the table.

Note: If the antenna unit is installed at a close distance in front of the wheel house,
prevent the transmission in that area to protect passengers and crew from microwave
radiation. Set the [Sector Blanks] in the [System] menu.

SAFETY INSTRUCTIONS

WARNING

ELECTRICAL SHOCK HAZARD

Do not open the equipment.

Only qualified persons can work
inside the equipment.

Turn off the power before you
service the antenna unit. Post a
warning sign near the power
switch not to turn on the power
while you service the antenna
unit.

Prevent the potential risk of being
struck by the rotating antenna and
exposure to RF radiation hazard.

When you work on the antenna
unit, wear a safety belt and hard
hat.

WARNING

Use the correct fuse.

A wrong fuse can damage the
equipment and cause fire.

Keep heater away from the
equipment.

Heat can change the equipment
shape and meltthe power cord, which
can cause fire or electrical shock.

Do not put liquid-filled containers
on the top of the equipment.

Fire or electrical shock can occur if a
liquid spills into the equipment.

Do not operate the equipment with
wet hands.

Serious injury or death can result
if a person falls from the radar
antenna mast.

Do not disassemble or modify
the equipment.

Fire or electrical shock can occur.

Turn off the power immediately
if water leaks into the equipment
or smoke or fire is coming
from the equipment.

Failure to turn off the equipment
can cause fire or electrical shock.

Electrical shock can occur.

SAFETY INSTRUCTIONS

CAUTION

WARNING

Do not depend on one navigation
device for the navigation of the
ship. The navigator must check all
aids available to confirm position.
Electronic aids are not a
replacement for basic navigation
principles and common sense.

· The ARPA automatically tracks an
automatically or manually acquired
radar target and calculates its
course and speed, indicating them
by a vector. Since the data from the
auto plotter depend on the selected
radar targets, the radar must be
optimally tuned for use with the auto
plotter, to ensure required targets
will not be lost or unnecessary
targets like sea returns and noise
will not be acquired and tracked.

· A target is not always a landmass,
reef, ship, but can also be returns
from the sea surface and from
clutter. As the level of clutter
changes with the environment, the
operator must correctly adjust the
A/C SEA, A/C RAIN and GAIN
controls so that the target echoes do
not disappear from the radar screen.

CAUTION

The plotting accuracy and response of
this ARPA meets IMO standards.
The tracking accuracy is affected by the
following:

· The tracking accuracy is affected by
course change. One to two minutes is
required to restore vectors to full
accuracy after a sudden 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 from ARPA and AIS are
intended for reference purposes only.

Check all available navigation aids to
determine target movement.

WARNING LABELS

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

To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.

WARNING

Radiation hazard. Only qualified
personnel should work inside scanner.
Confirm that TX has stopped before
opening scanner.
