SAFETY INSTRUCTIONS
DANGERDANGER
Stay away from transmitting antenna.
The radar antenna emits microwave radiation which can be harmful to the
human body, particularly the eyes. Never look directly into the antenna
radiator from a distance of less than 1 m when the radar is in operation.
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 and 10 W/m exist are given in the table
below.
Note: If the antenna unit is installed at a close distance in front of the wheel house,
your administration may require halt of transmission within a certain sector of antenna
revolution. This is possible - Ask your FURUNO representative or dealer to provide
this feature.

DANGER
WARNING
Before turning on the radar
make sure no one is near the
scanner unit.
Prevent the potential risk of
someone begin struck by the
rotating antenna and exposure
to RF radiation hazard.
WARNING
Do not open the equipment.
Improper handling can result in electrical
shock. Only qualified personnel shold
work inside the equipment.
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.
Use the proper fuse.
Fuse rating is shown in the chapter 5.
Use of a wrong fuse can result in equipment
damage
Do not operate the equipment with wet
hands.
Electrical shock can result.
CAUTION
No one navigation device should ever be
solely replied upon for the navigation of
a vessel.
Always confirm position against all available
aids to navigation, for safety of vessel and
crew.
The guard alarm is a useful anti-collision
aid, but does not relieve the operator of the
responsibility to also keep a visual lookout
for possible collision situations. The alarm
should never be used as the sole means for
detecting possible collision situations.
Continued use of the equipment 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.
Two warning labels are attached to the display
unit and scanner unit. Do not remove these label.
If labels are peeling off or are illegible, contact a
FURUNO agent or dealer.

SART (Search and Rescue Transponder)
iv
A Search and Rescue Transponder (SART) may be triggered by any X-Band (3 cm) radar
within a range of approximately 8 n.miles. Each radar pulse received causes it to transmit
a response which is swept repetitively across the complete radar frequency band. When
interrogated, it first sweeps rapidly (0.4 µsec) through the band before beginning a relatively slow sweep (7.5 µsec) 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 display , 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 n.miles, the radar display may show
also the 12 respopnses generated during the fast sweeps. These additional dot responses,
which also are equaly spaced by 0.64 nautical miles, will be interspersed with the original
line of 12 dots. They will appear slightly weaker and smaler than the original dots.

Showing SART marks on the radar display
To show the SART marks only on the radar display, detune the radar receiver by the
manual tuning out of best tuning condition. This erases or weakens all normal radar echoes, but, the SART marks are not erased because the SAR T response signal scans over
all frequencies in the 9 GHz band. When the radar approaches the SART in operation, the
SART marks will enlarge to large arcs, blurring a large part of the screen. Reduce the
sensitivity and adjust the sea clutter control of the radar.
iii
Summary to detect SART response
v
1. Use range scale of 6 or 12 nm as the spacing between the SART responses is about
0.6 nm (1125 m) to distinguish the SART.
2. Turn off the A/C AUTO function.
3. Turn off the Interference Rejector.
General remarks on receiving SART
Radar range scale
When looking for a SART it is preferable to use either the 6 or 12 nautical mile range scale.
This is because the total displayed length of the SART response of 12 (or 24) dots may
extend approximately 9.5 nautical miles beyond the position of the SART and it is necessary to see a number of response dots to distinguish the SART from other responses.
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 n.mile), the position at which the first dot is displayed may be
as mush as 0.64 n.mile 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.

1. PRINCIPLE OF OPERATION
1.1 What is Radar?
The term “RADAR” is an acronym meaning
RAdio Detection And Ranging. Although the
basic principles of radar were developed during World War II, echoes as an aid to navigation is not a new development.
1.2 How Ships Determined Position Before Radar
Before the invention of radar , when running in
fog near a rugged shoreline, ships would sound
a short blast on their whistles, fire a shot, or
strike a bell. The time between the origination
of the sound and the returning of the echo indicated how far the ship was from the cliffs or the
shore. The direction from which the echo was
heard indicated the relative bearing of the shore.
1.3 How Radar Determines Range
Radar determines the distance to the target by
calculating the time difference between the
transmission of a radar signal and the reception
of the reflected echo. It is a known fact that radar waves travel at a nearly constant speed of
162,000 nautical miles per second. Therefore
the time required for a transmitted signal to
travel to the target and return as an echo to the
source is a measure of the distance to the target. Note that the echo makes a complete round
trip, but only half the time of travel is needed to
determine the one-way distance to the target.
This radar automatically takes this into account
in making the range calculation.
1.4 How Radar Determines Bearing
The bearing to a target found by the radar is
determined by the direction in which the radar
scanner antenna is pointing when it emits an
electronic pulse and then receives a returning
echo. Each time the scanner rotates pulses are
transmitted in the full 360 degree circle, each
pulse at a slightly different bearing from the
previous one. Therefore, if one knows the direction in which the signal is sent out, one knows
the direction from which the echo must return.
1.5 Radar Wave Speed and Antenna Rotation Speed
Note that the speed of the radar waves out to
the target and back again as echoes is extremely
fast compared to the speed of rotation of the
antenna. By the time radar echoes have returned
to the scanner, the amount of scanner rotation
after initial transmission of the radar pulse is
extremely small.
1.6 The Radar Display
The range and bearing of a target are displayed
on what is called a Plan Position Indicator (PPI).
This display is essentially a polar diagram, with
the transmitting ship’s position at the center.
Images of target echoes are received and displayed at their relative bearings, and at their
distance from the PPI center.
With a continuous display of the images of tar gets, the motion of the transmitting ship is also
displayed.
