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/m
2
and 10 W/m
2
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.

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.

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

1.2 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 warm-
up 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 recom-
mended 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.

1.7 Presentation Modes
This radar has the following presentation modes:
Relative Motion (RM)
Head-up: Unstabilized display. Heading is at the top of the screen.
Course-up: Compass-stabilized relative to ship's orientation. The bearing scale rotates to place
ship’s heading (course set) at the screen top at the moment the course-up mode is selected.
North-up: Compass-stabilized with reference to north. Bearing scale is fixed.
True Motion (TM)
North-up: Ground or sea stabilized with compass and speed inputs. Own ship moves on the dis-
play. Landmasses and sea are fixed.
1.7.1 Choosing presentation mode
Press the MODE key consecutively to choose presentation mode desired. The presentation mode
in use appears at the top left corner on the screen.
All modes except head-up require a heading signal, in AD-10 format or NMEA
format. If the heading signal is lost, the mode is changed to head-up and the north
marker disappears. Further, the heading readout shows XXX.X and the message
“GYRO” (AD-10 format data) or “NMEA-HEAD” (NMEA format data) appears in the
alarm message display. Restore gyro input and confirm bearing.
1.7.2 Description of presentation modes
Head-up mode
The head-up mode is a display in which the line con-
necting own ship and the top of the display indicates own
ship's heading.
The target pips are painted at their measured distances
and in their directions relative to own ship's heading.
Echoes may be unstable in severe yawing and turning.
A short line on the bearing scale is the north marker, indi-
cating heading sensor north.

Course-up mode
The course-up mode is an azimuth stabilized dis-
play in which a line connecting the center with the
top of the display indicates own ship's intended
course (namely, own ship's previous heading just
before this mode has been selected).
Target pips are painted at their measured dis-
tances and in their directions relative to the
intended course, which is maintained at the 0-
degree position. The heading line moves in accor-
dance with ship's yawing and course change. This
mode is useful to avoid smearing of picture during
course change.
North-up mode
The north-up mode paints target pips at their measured dis-
tances and in their true (heading sensor) directions from own
ship, north bearing maintained at the top of the screen. The
heading line changes its direction according to the ship's
heading.
True motion mode
Own ship and other moving objects move in accordance with
their true courses and speed. In ground stabilized TM, all
fixed targets, such as landmasses, appear as stationary
echoes.
When own ship reaches a point corresponding to 75% of the
radius of the display, own ship position is automatically reset
to a point of 75% radius opposite to the extension of the
heading line passing through the display center. You may
also reset the own ship symbol manually by pressing the OFF
CENTER key. The method of resetting is the same as men-
tioned above.

1. Push the A/C SEA control to show “SEA MAN” as the A/C SEA adjustment method.
2. Rotate the A/C SEA control to suppress sea clutter.
The proper setting of the A/C SEA control is such that the clutter is broken up into small dots, and
small targets become distinguishable. If the setting is set too low, targets will be hidden in the
clutter, while if the setting is too high, both sea clutter and targets will disappear from the display.
In most cases adjust the control until clutter has disappeared to leeward, but a little is still visible
windward.

1.12 Suppressing Rain Clutter
The vertical beamwidth of the antenna is designed to see surface targets even when the ship is
rolling. However, by this design the unit will also detect rain clutter (rain, snow, or hail) in the same
manner as normal targets.
The A/C RAIN control adjusts the receiver sensitivity as the A/C SEA control does but rather in a
longer time period (longer range). The higher the setting the greater the anti-clutter effect. When
echoes from precipitation mask solid targets, adjust the control to split up these unwanted echoes
into a speckled pattern, making recognition of solid targets easier.
1.12.1 Choosing rain clutter adjustment method
Rain clutter may be adjusted automatically or manually. Push the A/C RAIN 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 rain clutter adjustment method is

1.15 Interference Rejector
Mutual radar interference may occur in the vicinity of another shipborne radar operating in the
same frequency band (9 GHz). It is seen on the screen as a number of bright spikes either in irreg-
ular patterns or in the form of usually curved spoke-like dotted lines extending from the center to
the edge of the picture. Activating the interference rejector circuit can reduce this type of interfer-
ence.

1.16 Measuring the Range to a Target
The range to a target may be measured three ways: with the fixed range rings, with the cursor (if
set to measure range and bearing), and with the VRM.
Use the fixed range rings to obtain a rough estimate of the range to a target. They are the concen-
tric solid circles about own ship, or the sweep origin. The number of rings is automatically deter-
mined by the selected range scale and their interval is displayed at the upper-left position of the
screen. Count the number of rings between the center of the display and the target. Check the
range ring interval and judge the distance of the echo from the inner edge of the nearest ring.
1.16.1 Measuring range by the variable range marker (VRM)
There are two VRMs, No. 1 and No. 2, which appear as dashed rings so that you can discriminate
them from the fixed range rings. The two VRMs can be distinguished from each other by different
lengths of dashes.
1. Press the VRM key to display either of the VRMs. Successively pressing the VRM key toggles
the active VRM between No. 1 and No. 2. The currently active marker is enclosed with >.....<
in the VRM indication box.
2. Operate the Trackball to align the variable range marker with the inner edge of the target of
interest and read its distance at the lower-right corner of the screen. Each VRM remains at the
same geographical distance when you operate the RANGE key. This means that the apparent
radius of the VRM ring changes in proportion to the selected range scale.
3. You may “anchor” the VRM by choosing it and pressing the ENTER key.
4. To erase a VRM, make it active and press the CANCEL/HL OFF key.

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.

1.20 Target Alarm
The target alarm serves to alert the navigator to
targets (ships, landmasses, etc.) entering a set
area, with audio and visual alarms.
The alarm may be set to sound against targets
entering or exiting the zone. See paragraph 1.20.3.
1.20.1 Setting a target alarm
The procedure which follows shows you how to set
a target alarm, using the illustration below as an
example.
1. Press the TARGET ALARM key to activate ALARM 1 or ALARM 2 as appropriate.
2. Use the trackball to drag the cursor to the location “A” and press the ENTER key.
3. Drag the cursor to the location “B” and press the ENTER key.
How to set a target alarm zone
•If you wish to create a target alarm zone having a 360-degree coverage around own
ship, set point "B" in almost the same direction as point "A."
•When the target alarm zone is not within the range in use, the indication OUTRNG
replaces ALARM1(or 2)_IN(or OUT) in the alarm status area. In this case choose a
range which will display the target alarm zone.
1.20.2 Silencing the audio alarm
A target in the target alarm zone produces both visual (flashing) and audio (beep) alarms. To
silence the audio alarm, press any key. This will deactivate the audio alarm but will not stop the
flashing of the offending target.
CAUTION
• The alarm should not be relied upon as
the sole means for detecting possible
collision situations.
• A/C SEA, A/C RAIN and GAIN controls
should be properly adjusted to be sure
the alarm system does not overlook
target echoes.

1.24 Echo Averaging
To distinguish real target echoes from sea clutter, echoes are averaged over successive picture
frames. If an echo is solid and stable, it is presented in its normal intensity. Sea clutter is averaged
over successive scans resulting in reduced brilliance, making it easier to discriminate real targets
from sea clutter.
•Do not use the echo average function under heavy pitching and rolling; loss of target
detection can result.
•This feature requires a heading signal. When the signal becomes lost, echo average
is automatically disabled.
To properly use the echo average function, it is recommended to first suppress sea clutter with
the A/C SEA control. Then, do as follows:
1. Press the MENU key to open the menu.
2. Choose the Echo menu and press the ENTER key.
3. Choose Echo Average and press the ENTER key.

1.29 Custom Setup
1.29.1 About custom setup
Every time your navigating environment or task changes, you must adjust the radar, which can be
a nuisance in a busy situation. Instead of changing radar settings case by case, it is possible to
assign the CUSTOM key to provide optimum settings for often encountered situations.
The radar's internal computer offers three default custom setups (see the table below). However,
you may customize these settings to meet your navigation needs, on the Custom 1, Custom 2 and
Custom 3 menus.
To enable a custom setup, press the CUSTOM key. Each press of the key enables Custom1,
Custom2 or Custom3 cyclically. (Custom setup numbers which are turned off will be skipped.) The
chosen custom setup name is shown at the top left corner. To escape from custom setup, operate

The minimum range is defined by the shortest distance at which, using a scale of 1.5 or 0.75 nm,
a target having an echoing area of 10 m2 is still shown separate from the point representing the
antenna position.
It is mainly dependent on the pulse length, antenna height, and signal processing such as main
bang suppression and digital quantization. It is a good practice to use a shorter range scale as far
as it gives favorable definition or clarity of picture. This series of radars satisfy the requirement of
IEC 62252 5.14.1 (Class A).
Maximum range
The maximum detecting range of the radar, Rmax, varies considerably depending on several fac-
tors such as the height of the antenna above the waterline, the height of the target above the sea,
the size, shape and material of the target, and the atmospheric conditions.
Under normal atmospheric conditions, the maximum range is equal to the radar horizon or a little
shorter. The radar horizon is longer than the optical one by about 6% because of the diffraction
property of the radar signal. The Rmax is given in the following equation.
where Rmax: radar horizon (nautical miles)
h1: antenna height (m)
h2: target height (m)
For example, if the height of the antenna above the waterline is 9 meters and the height of the
target is 16 meters, the maximum radar range is;
It should be noted that the detection range is reduced by precipitation (which absorbs the radar
signal).

2.1.2 Radar resolution
There are two important factors in radar resolution (discrimination): bearing resolution and range
resolution.
Bearing resolution
Bearing resolution is the ability of the radar to display as separate pips the echoes received from
two targets which are at the same range and close together. It is proportional to the antenna length
and reciprocally proportional to the wavelength. The length of the antenna radiator should be
chosen for a bearing resolution better than 4.5 degrees (IEC 62252 Class A). This condition is nor-
mally satisfied with a radiator of 1.2 m (4 ft) or longer in the X-band.
Range resolution
Range resolution is the ability to display as separate pips the echoes received from two targets
which are on the same bearing and close to each other. This is determined by pulse length only.
Test targets for determining the range and bearing resolution are radar reflectors having an
echoing area of 10 m2.
2.1.3 Bearing accuracy
One of the most important features of the radar is how accurately the bearing of a target can be
measured. The accuracy of bearing measurement basically depends on the narrowness of the
radar beam. However, the bearing is usually taken relative to the ship's heading, and thus, proper
adjustment of the heading line at installation is an important factor in ensuring bearing accuracy.
To minimize error when measuring the bearing of a target, put the target echo at the extreme posi-
tion on the screen by selecting a suitable range.
2.1.4 Range measurement
Measurement of the range to a target is also a very important function of the radar. Generally,
there are two means of measuring range: the fixed range rings and the variable range marker
(VRM). The fixed range rings appear on the screen with a predetermined interval and provide a
rough estimate of the range to a target. The variable range marker's diameter is increased or
decreased so that the marker touches the inner edge of the target, allowing the operator to obtain
more accurate range measurements.
2. RADAR OBSERVATION
2-3
2.2 False Echoes
Occasionally echo signals appear on the screen at positions where there is no target or disappear
even if there are targets. They are, however, recognized if you understand the reason why they
are displayed. Typical false echoes are shown below.
2.2.1 Multiple echoes
Multiple echoes occur when a transmitted pulse returns from a solid object like a large ship, bridge,
or breakwater. A second, a third or more echoes may be observed on the display at double, triple
or other multiples of the actual range of the target as shown below. Multiple reflection echoes can
be reduced and often removed by decreasing the gain (sensitivity) or properly adjusting the A/C
SEA control.
Multiple echoes
2.2.2 Sidelobe echoes
Every time the radar pulse is transmitted, some radiation escapes on each side of the beam,
called “sidelobes.” If a target exists where it can be detected by the sidelobes as well as the main
lobe, the side echoes may be represented on both sides of the true echo at the same range. Side
lobes show usually only on short ranges and from strong targets. They can be reduced through
careful reduction of the gain or proper adjustment of the A/C SEA control.

2.2.3 Virtual image
A relatively large target close to your ship may be represented at two positions on the screen. One
of them is the true echo directly reflected by the target and the other is a false echo which is
caused by the mirror effect of a large object on or close to your ship as shown in the figure below.
If your ship comes close to a large metal bridge, for example, such a false echo may temporarily
be seen on the screen.
Virtual image
2.2.4 Shadow sector
Funnels, stacks, masts, or derricks in the path of the antenna block the radar beam. If the angle
subtended at the antenna is more than a few degrees, a non-detecting sector may be produced.
Within this sector targets can not be detected.

2.3 SART (Search and Rescue Transponder)
2.3.1 SART description
A Search and Rescue Transponder (SART) may be triggered by any X-band (3 cm wavelength)
radar within a range of approximately 8 nm. Each radar pulse received causes it to transmit a
response which is swept repetitively across the complete radar frequency band. When interro-
gated, it first sweeps rapidly (0.4 µs) through the band before beginning a relatively slow sweep
(7.5 µs) through the band back to the starting frequency. This process is repeated for a total of
twelve complete cycles. At some point in each sweep, the SART frequency will match that of the
interrogating radar and be within the pass band of the radar receiver. If the SART is within range,
the frequency match during each of the 12 slow sweeps will produce a response on the radar dis-
play, thus a line of 12 dots equally spaced by about 0.64 nautical miles will be shown.
When the radar to the SART is reduced to about 1 nm, the radar display my show also the 12
responses generated during the fast sweeps. These additional dot responses, which also are
equally spaced by 0.64 nautical miles, will be interspersed with the original line of 12 dots. They
will appear slightly weaker and smaller than the original dots.

2.3.2 General remarks on receiving SART
SART range errors
When responses from only the 12 low frequency sweeps are visible (when the SART is at a range
greater than about 1 nm), the position at which the first dot is displayed may be as much as 0.64
nm beyond the true position of the SART. When the range closes so that the fast sweep responses
are seen also, the first of these will be no more than 150 meters beyond the true position.
Radar bandwidth
This is normally matched to the radar pulse length and is usually switched with the range scale
and the associated pulse length. Narrow bandwidths of 3-5 MHz are used with long pulses on long
range scales and wide bandwidths of 10-25 MHz with short pulses on short ranges.
A radar bandwidth of less than 5 MHz will attenuate the SART signal slightly, so it is preferable to
use a medium bandwidth to ensure optimum detection of the SART.
Radar side lobes
As the SART is approached, side lobes from the radar antenna may show the SART responses
as a series of arcs or concentric rings. These can be removed by the use of the anti-clutter sea
control although it may be operationally useful to observe the side lobes as they may be easier to
detect in clutter conditions and also they will confirm that the SART is near to own ship.
Note: SART information excerpted from IMO SN/Circ 197 OPERATION OF MARINE RADAR
FOR SART DETECTION.
2.4 RACON
A RACON is a radar beacon which emits radar receivable signals in the radar frequency spectrum
(X- or S-band). There are several signal formats; in general, the RACON signal appears on the
radar screen as a rectangular echo originating at a point just beyond the position of the radar
beacon. It has a Morse coded pattern. Note that the position on the radar display is not accurate.

3. ARP OPERATION
The Automatic Radar Plotter ARP-11 (option) manually or automatically acquires and tracks ten
targets. Once a target is acquired automatically or manually it is automatically tracked within 0.1
to 16 nm.
3.1 Usage Precautions
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 auto plotter automatically tracks an
automatically or manually acquired radar
target and calculates its course and
speed, indicating them by a vector. 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 auto plotter 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.
Display accuracy is affected by the
following:
• Echo intensity
• Radar transmission pulsewidth
• Radar bearing error
• Gyrocompass error
• Course change (own ship or target)

3.6 Vector Attributes
What is a vector?
A vector is a line extending from a tracked target which shows speed and course of the target. The
vector tip shows estimated position of the target after the selected vector time elapses. It can be
useful to extend the vector length (time) in order to evaluate the risk of collision with any target.
Vector
Vector time, vector reference
Vector time can be set to 30 seconds, 1, 3, 6, 15 or 30 minutes. You may reference the vectors to
North (True, requires heading and speed data) or ship's heading (relative) as desired.
1. Press the MENU key to open the menu.
2. Choose Target and press the ENTER key.

5. Choose Vector Reference and press the ENTER key.
6. Choose Relative or True as appropriate and press the ENTER
key.
Relative: Other ships move relative to own ship. This mode is
useful as an anti-collision aid. If a vessel is on a collision course
with own ship its vector will be pointing toward own ship position.
True: Own ship and other ships move at their true motions. This
mode is useful for discriminating between moving and stationary
targets.

3.9 CPA/TCPA Alarm
When the predicted CPA of any ARP target or AIS target becomes smaller than the preset CPA
alarm range and its predicted TCPA less than the preset TCPA alarm limit, the audio alarm sounds
and the target plot symbol of the offending target changes to a triangle and flashes together with
its vector. You may silence the audio alarm with the CANCEL/HL OFF key. The flashing of the
triangle plot stops when the vessel’s CPA and TCPA are out of the CPA and TCPA alarm setting.
The ARP continuously monitors the predicted range at the Closest Point of Approach (CPA) and
predicted time to CPA (TCPA) of each track to own ship.
This feature helps alert you to targets which may be on a collision course with own ship. However,
it is important that GAIN, A/C SEA, A/C RAIN and other radar controls are properly adjusted and
the ARP is set up so that it can track targets effectively.
1. Press the MENU key to open the menu.
2. Choose Target and press the ENTER key.

CAUTION
The CPA/TCPA alarm should never be
relied upon as the sole means for detect-
ing the risk of collision. The navigator is
not relieved of the responsibility to keep
visual lookout for avoiding collisions,
whether or not the radar or other plotting
aid is in use.

4.10 Vector Attributes
What is a vector?
A vector is a line extending from a tracked target which shows course of the AIS target. The vector
tip shows estimated position of the target after the selected vector time elapses. It can be useful
to extend the vector length (time) in order to evaluate the risk of collision with any target. (See the
illustration on page 4-2 for the appearance of a vector.)
Vector time, vector reference
Vector time can be set to 30 seconds, 1, 3, 6, 15 or 30 minutes. Vectors may be displayed in True
or Relative motion.

Relative: Other ships move relative to own ship. This mode is
useful as an anti-collision aid. If a vessel is on a collision course
with own ship its vector will be pointing toward own ship position.
True: Own ship and other ships move at their true motions. This
mode is useful for discriminating between moving and stationary
targets.

This chapter provides the necessary procedures for maintenance and troubleshooting. Follow the
recommended procedures to keep your radar in good working order.
WARNING
Do not open the equipment.
Hazardous voltage which can
cause electrical shock exists
inside 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.
NOTICE
Do not apply paint, anti-corrosive
sealant or contact spray to coating
or plastic parts of the equipment.
Those items contain organic solvents
that can damage coating and plastic
parts, especially plastic connectors.
6. MAINTENANCE & TROUBLESHOOTING

necessary
LCD The LCD will, in time,
accumulate a coating of
dust which tends to dim
the picture.
Wipe the LCD carefully to prevent
scratching, using tissue paper and an
LCD cleaner. To remove dirt or salt
deposits, use an LCD cleaner, wiping
slowly with tissue paper so as to dissolve
the dirt or salt. Change paper frequently
so the salt or dirt will not scratch the
LCD. Do not use solvents such as
thinner, acetone or benzene for
cleaning. Also, do not use degreaser or
antifog solution, as they can strip the
coating from the LCD.

6.2 Fuse Replacement
A fuse is in the fuse holder on the power cable and inside the power supply unit, and they protect
the equipment from reverse polarity of the ship's mains and equipment fault. If a fuse blows, find
out the cause before replacing it. Use the correct fuse. Using the wrong fuse will damage the
equipment and void the warranty.
6.3 Magnetron Life
When the magnetron (generates microwaves) has expired, distant targets cannot be seen on the
display. When you feel that long range performance has decreased, contact a FURUNO agent or
dealer about replacement of the magnetron.
6.4 LCD Backlight Life
The life of the LCD backlight, which provides illumination for the LCD, is approximately 4,300
hours. The display brilliance cannot be raised when the backlight has worn out. Have a qualified
technician replace the backlight when brilliance cannot be raised.
