SAFETY INSTRUCTIONS
WARNING
Radio Frequency Radiation Hazard
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 Mandatory Action
Prohibitive Action
Read these safety instructions before you operate the equipment.
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.
The distances at which RF radiation levels of 100 W/m
2
and 10 W/m
2
exist 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.

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.
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.
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.
Electrical shock can occur.
WARNING
SAFETY INSTRUCTIONS
iv
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
CAUTION
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
Radiation hazard. Only qualified
personnel should work inside scanner.
Confirm that TX has stopped before
opening scanner.

1.2 How to Turn the Radar On/Off and Transmit
Press the key to turn on the radar.To turn off the radar, press and hold the key
until the screen turns off.
When you turn on the power, the initialization screen appears followed by the start-up
screen. The start-up screen shows the model name, program number and the results
of the ROM and RAM check, "OK" or "NG" (No Good). If "NG" appears, contact your
dealer for instruction.
Start-up screen
After the self-tests have completed, the bearing scale and a digital timer appear. The
digital timer counts down the time necessary to warm the magnetron, which transmits
the radar pulses. The time to warm the magnetron is 90 seconds for FR-8045/FR-
8065 and FR-8125 radars, 180 seconds for FR-8255 radar.
After the timer reads 0:00, the STBY screen appears. The STBY screen has three
types. (See paragraph 1.44.2.) The radar is ready to transmit the radar pulses. Press
the STBY/TX key to transmit the radar pulses.
The STBY/TX key switches between standby and transmit. The antenna rotates in
transmit and is stopped in standby. The magnetron gets old with use. To increase the
life of the magnetron, set the radar in standby when you do not use the radar.
Quick start
If the magnetron is still warm, you can get the radar to TRANSMIT without the warm
up time. When the key is turned off by accident, turn on the key within 10
seconds after you turn off the power.

moves with the course selected. If you select a new
course, select the course up mode again to display
the new course at the top of the display. Targets are
shown at their measured distances and their direc-
tions relative to the set course, which is at the 0-de-
gree position. The heading line moves according to
the yawing and any course change.
North up mode
Targets are shown at their measured distances and
their true (compass) directions from your ship. North is
at the top of the screen. The heading line changes its
direction according to your heading.

1.15 How to Measure the Range to a Target
You can measure the range to a target in three methods. You can use the fixed range
rings, the cursor (if set to measure range and bearing) and the VRM (Variable Range
Marker).
Use the fixed range rings to get a rough estimate of the range to a target. The fixed
range rings are the concentric solid circles about your ship. The number of rings
changes with the selected range scale. The interval of the range ring is displayed at
the upper-left corner of the screen. Count the number of rings between the center of
the display and the target. Check the range ring interval and measure the distance of
the echo from the nearest ring.

the No. 2 VRM.
1. Press the VRM key to display either of the VRMs. Press the VRM key to change
the active VRM between No. 1 and No. 2. The indication of the currently active
VRM is in a rectangle.
2. Use the CursorPad to align the Variable Range Marker with the inner edge of the
target. Read the distance at the lower-right corner of the screen. Each VRM re-
mains at the same geographical distance when you operate the RANGE key. The
size of the VRM ring changes in proportion to the selected range scale.
3. Press the ENTER key to anchor the VRM.
4. To erase a VRM, press the VRM key to activate the VRM and press the CANCEL/
HL OFF key.

1.26 How to Hide the Heading Line Temporarily
The heading line indicates the heading of your ship in all display modes. The heading
line is a line from your ship position to the outer edge of the radar display area. The
heading line appears at zero degrees on the bearing scale in head up and true view
modes. The heading line changes the orientation depending on the ship orientation in
north up and true motion modes and when the course is changed in the course up
mode.
To hide the heading line (and all marks for River and Sea purpose) and display only
targets, press and hold the CANCEL/HL OFF key. To display the heading line again,
release the key.

The wiper feature automatically reduces the brilliance of unwanted weak signals
(noise, sea clutter, rain clutter, etc.) and unnecessary signals, like radar interference,
to clear the picture of unnecessary echoes. The result of wiper depends on the wiper
setting used and whether echo averaging is turned on or off, as described below.
Processing content A: The brilliance of unnecessary weak echoes, like noise and ra-
dar interference, is reduced to clear the picture. The difference between wiper 1 and
2 is that brilliance is lowered more slowly in 1.
Processing content B: Echo averaging is automatically turned from off to on when
the wiper feature is turned on. You can see how the picture changes with the echo av-
eraging turned off and turned on.
To activate the wiper feature, do the following:
1. Press the MENU key to open the menu.

1.33 Watchman
The Watchman sounds the buzzer to tell the operator to check the radar display. The
radar transmits for one minute and then goes into standby for the selected time inter-
val. If the target alarm is active and a target is found in the alarm zone, Watchman is
cancelled, and the radar transmits continuously.
How watchman operates
In standby, the timer near the <WATCH> label at the center of the screen counts down
the remaining time until the transmission. When the set time interval has passed, the
audio alarm sounds, the timer disappears and the radar transmits for one minute. After
one minute, the audio alarm sounds, the radar stops transmitting and the watch alarm
timer again begins the countdown sequence.
If you press the STBY/TX key before the set time interval comes, the radar goes into
transmission.

2. DESCRIPTION OF RADAR
2.1 General
2.1.1 Minimum and maximum ranges
Minimum range
The minimum range is defined by the shortest distance at which, using a scale of
0.0625 or 0.125 nm, a target that has an echoing area of 10 m2 is shown separate from
the point that shows the antenna position.
The minimum range depends on the pulselength, antenna height, and signal process-
ing (like main bang suppression and digital quantization). Use a shorter range scale
as far as it gives favorable definition or clarity of picture.
The FR-8045/FR-8065/FR-8125/FR-8255 radar series meets the requirements of
IEC 62252 5.14.1 (Class A).
Maximum range
The maximum detection range, Rmax, changes depending on the height of the anten-
na, 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 or a little shorter
than the optical horizon. The radar horizon is longer than the optical one by approxi-
mately 6%, because of the diffraction property of the radar signal. The Rmax is shown
in the following formula.
If the height of the antenna is 9 m and the height of the target is 16 m, the maximum
radar range is;
Note: The detection range is reduced by any precipitation (which absorbs the radar
signal).

2.1.2 Radar resolution
The bearing resolution and range resolution are important in radar resolution.
Bearing resolution
The bearing resolution is the ability of the radar to display the echoes received from
two targets at the same range as the separate echoes. The bearing resolution is pro-
portional to the antenna length and the wavelength.
Bearing resolution
Range resolution
The range resolution is the ability to display the echoes received from two targets on
the same bearing as separate echoes. The range resolution is calculated by only
pulselength.
The test targets used to calculate the range and bearing resolution are radar reflectors
that have 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 tar-
get can be measured. The accuracy of bearing measurement depends on the narrow-
ness of the radar beam. The bearing taken is relative to the heading of the ship.
Correct adjustment of the heading line at installation is important to get accurate bear-
ings. To minimize the error when you measure the bearing of a target, put the target
echo at the extreme position on the screen by selecting a suitable range.
2.1.4 Range measurement
Measurement of the range to a target is important function of the radar. There are
three methods to measure range: the fixed range rings, the Variable Range Marker
(VRM), and the cursor (if the cursor is set to measure range and bearing). The fixed
range rings appear on the screen with a given interval and provide a rough estimate
of the range to a target. The diameter of VRM is increased or decreased so that the
marker touches the inner edge of the target (see paragraph 1.15.2). The VRM is a
more accurate range measurement than the fixed range rings. For cursor, see
section 1.13.
2.2 False Echoes
The echo signals can appear on the screen at positions where there is no target or
disappear when there are targets. These 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 can be seen on the dis-
play at double, triple or other multiples of the actual range of the target as shown be-
low. You can reduce and remove the multiple reflection echoes with the A/C SEA
control.

2. DESCRIPTION OF RADAR

2.2.2 Sidelobe echoes
When the radar pulse is transmitted, some radiation escapes on each side of the
beam, called "sidelobes”. If a target is where a target can be detected by the sidelobes
as well as the mainlobe, the side echoes can be shown on both sides of the true echo
at the same range. Sidelobes show normally only on short ranges and from strong tar-
gets. You can reduce the sidelobes with the A/C SEA control.
2.2.3 Virtual image
A large target close your ship can appear at two positions on the screen. One of them
is the true echo reflected by the target. The other is a false echo which is caused by
the mirror effect of a large object on or close your ship as shown in the following figure.
If your ship comes near a large metal bridge, for example, a false echo can temporarily
appear on the screen.

2.2.4 Shadow sector
Funnels, stacks, masts, or derricks near the antenna interrupt the radar beam, and a
non-detecting sector can occur. Radar can not detect targets within this sector.
2.3 SART (Search and Rescue Transponder)
2.3.1 SART description
A Search and Rescue Transponder (SART) responds to any X-band (3 cm) radar with-
in a range of approximately 8 nm. Each radar pulse received causes the SART to
transmit a response which is swept continuously across the complete radar frequency
band.

2.3.2 General remarks on receiving SART
SART range errors
When the SART is at a range greater than approximately 1 nm, the first dot is dis-
played at 0.64 nm past the true position of the SART. When the range closes so that
the fast-sweep responses are also seen, the first range echoes are displayed at 150
m past the true position.
Range scale
When you find the SART position, do as follows:
1. Use the RANGE key to set the range scale to 6 nm or 12 nm.
2. Turn off [A/C Auto].
3. Turn off [Int Rejector].
SART display
To display only the SART echo clearly on the radar screen, reduce the tuning on man-
ual mode. The normal radar echoes get weak, but the SART echoes remain. Your ship
comes near the SART, the arc for the SART display becomes larger. Most of the radar
screen becomes fuzzy. Adjust the A/C SEA and GAIN controls to display the neces-
sary screen.
2.4 RACON
The RACON is a RAdar beaCON which sends 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 an echo in the shape of a rectangle
originating at a point just past the position of the radar beacon. It has a Morse coded
pattern. Note that the position on the radar display is not accurate.

3. ARPA OPERATION
The Automatic Radar Plotter ARP-11 (option) manually or automatically acquires and
tracks ten targets. When a target is acquired automatically or manually, a target is au-
tomatically tracked within 0.1 to 16 nm.
3.1 Precautions for Use
3.2 Controls for Use with ARPA
ENTER: Acquire the cursor-selected target. Display data for tracked target (in the data
box at the bottom of the screen).
CANCEL/HL OFF: Remove data of cursor-selected tracked target from the data box.
Stop tracking the cursor-selected target (when its data is not displayed in the data
box).
MENU: Access the [Target] and [ARPA] menus for ARPA operations.
CursorPad: Select a target to acquire (or cancel the tracking). Select a target to show
(or remove) target data.
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 be returns from the sea
surface and 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.
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 display accuracy is affected by the
following:
· Echo intensity
· Pulse width of radar transmission
· Radar bearing error
· Gyrocompass error
· Course change (your ship or target)

Target number
[River] and [Sea] (Non-IEC system): An acquired target gets the youngest unused
number. When a target is lost and disappears from the number list, the next acquired
target takes the number of that lost target (ie: In a five-target list, if the target 2 is lost,
the next acquired target takes the number of target 2).
[IEC] and [Russian-River] (IEC system): An acquired target gets the youngest un-
used number. When a target is lost and disappears from the number list, the next ac-
quired target takes the next sequential number until reaching a maximum 10. If the
target number reaches a maximum 10, the next acquired target takes the number of
a previously lost target.
