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 W/m2 and 10 W/m2 exist are given in the
table below.
Note: If the antenna unit is installed at a close distance in front of the wheel house, it may
be necessary to prevent transmission in that area to protect passengers and crew from
microwave radiation. This can be done with Sector Blank in the System menu.
Model Antenna Distance to
100 W/m2 point Distance to
10 W/m2 point
FR-8062 XN-12A Nil 1.20 m
XN-13A Nil 1.10 m
FR-8122 XN-12A Nil 1.90 m
XN-13A Nil 1.40 m
FR-8252 XN-12A 0.40 m 4.60 m
XN-13A 0.40 m 3.10 m

SAFETY INSTRUCTIONS

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.
Turn off the power immediately if water
leaks into the equipment or the equip-
ment is emitting smoke or fire.
Continued use of the equipment can cause
fire or electrical shock.
WARNING
Use the proper fuse.
Fuse rating is shown on the equipment.
Use of a wrong fuse can result in damage
to the equipment.
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 on
the top of 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.

SAFETY INSTRUCTIONS
iv
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.
• The 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 ARP 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 and AIS are
intended for reference purposes only.
Check all available navigation aids to
determine target movement.
WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.
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
Radiation hazard. Only qualified
personnel should work inside scanner.
Confirm that TX has stopped before
opening scanner.

1.11 Suppressing Sea Clutter
Echoes from waves cover the central part of the display with random signals known as sea clutter.
The higher the waves, and the higher the antenna above the water, the further the clutter will
extend. When sea clutter masks the picture, use the A/C SEA control to suppress the clutter,
either manually or automatically.
1.11.1 Choosing sea clutter adjustment method
Push the A/C SEA control to choose automatic or manual adjustment alternately. The adjustment
method currently chosen is show at the top right corner of the screen. In the example below the
sea clutter adjustment method is “AUTO”.

1.18 Measuring the Bearing to a Target
Use the Electronic Bearing Lines (EBLs) to take bearings of targets. There are two EBLs, No. 1
and No. 2. Each EBL is a straight dashed line extending out from the own ship position up to the
circumference of the radar picture. The fine dashed line is the No. 1 EBL and the coarse dashed
one is the No. 2 EBL.
1.18.1 Measuring the bearing with an EBL
1. Press the EBL key to display either of the EBLs. Successively pressing the EBL key toggles
the active EBL between No. 1 and No. 2. The currently active marker is enclosed with >.....< in
the EBL indication box.
2. Operate the Trackball to bisect the target of interest with the EBL and read its bearing at the
lower-left corner of the screen.
3. You may “anchor” an EBL by choosing it and pressing the ENTER key.
4. To erase an EBL, make it active and press the CANCEL/HL OFF key.
