IMPORTANT NOTICES
General
• The operator of this equipment must read and follow the descriptions in this manual. 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 FURUNO
will cancel the warranty.
• All brand and product names are trademarks, registered trademarks or service marks of their
respective holders.
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.
Cd
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
Ni-Cd
Pb
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.
SAFETY INSTRUCTIONS
Read these safety instructions before you operate the equipment.
WARNING
Indicates a condition that can cause death or serious
injury if not avoided.
CAUTION
Indicates a condition that can cause minor or moderate
injury if not avoided.
Warning, Caution
Prohibitive Action
Mandatory Action
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.

SAFETY INSTRUCTIONS
WARNING
ELECTRICAL SHOCK HAZARD
WARNING
Use the proper fuse.
Do not open the equipment.
Only qualified personnel
should work inside the
equipment.
Fuse rating is shown on the equipment.
Use of a wrong fuse can result in damage
to the equipment.
Keep heater away from equipment.
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
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.
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.
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 equipment is emitting smoke or fire.
Continued use of the equipment can cause
fire or electrical shock.

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.
• 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 landmass, 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.
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.

Type: 03-142-3201-0
Code No.: 100-266-890
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.
TFT LCD
The high quality TFT (Thin Film Transistor)
LCD displays 99.999% of its picture
elements. The remaining 0.001% may
drop out or light, however this is an
inherent property of the LCD; it is not a
sign of malfunction.

Turning the Radar On/Off, Transmitting
Press the POWER/BRILL key at the top of the control panel to turn the radar on, and the lamp to
its left lights. To turn the radar off, press and hold down the key until the screen turns black.
At power-up, the start-up screen appears, showing the model name, program number and the
results of the ROM and RAM check, OK or NG (No Good). If an NG appears, try pressing any key
other than the power key to proceed. If normal operation is not possible, contact your dealer for
advice.

Start-up screen
After the tests are completed, the bearing scale and a digital timer appear. The digital timer counts
down the time remaining to warm up the magnetron, which transmits the radar pulses. This warmup takes 180 sec. (FR-8252) or 90 sec. (FR-8062, FR-8122).
After the timer has counted down to 0:00, the STBY screen appears, the appearance of which you
may choose according to your needs. (For further details, see paragraph 1.41.2.) The radar is now
ready to transmit radar pulses. Press the STBY/TX key to transmit radar pulses.
The STBY/TX key toggles between stand-by and transmit status. The antenna rotates in transmit
condition and is stopped in standby. Because the magnetron ages with use it is highly recommended to set the radar in standby when it will not be required, to extend the life of the magnetron.
Quick start
Provided that the radar was once in use with the transmitter tube (magnetron) still warm, you can
get the radar into TRANSMIT condition without the warm-up. If the POWER/BRILL key was
turned off by mistake or the like and you wish to restart the radar promptly, turn on the POWER/
BRILL key not later than 10 seconds after power-off. This feature is not available with the
FR-8252.
