SAFETY INSTRUCTIONS

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

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.

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.

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 equip-

ment is emitting smoke or fire.

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.

WARNING

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.

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.

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.

SART (Search and Rescue Transponder)

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 rela-

tively 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 ech-

oes, 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.

Summary to detect SART response

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 neces-

sary 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.

1.1 What is Radar?

The term “RADAR” is an acronym meaning

RAdio Detection And Ranging. Although the

basic principles of radar were developed dur-

ing World War II, echoes as an aid to naviga-

tion 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 indi-

cated 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 ra-

dar 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 tar-

get. 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. PRINCIPLE OF OPERATION

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 di-

rection 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 dis-

played 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.
