Radio Frequency Radiation Hazard

The radar antenna emits electromagnetic radio frequency (RF) energy that 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 level of 100, 50 and 10 W/m

SAFETY INSTRUCTIONS

WARNING

Do not open the equipment.

The equipment uses high voltage that
can cause electrical shock. Refer any
repair work to a qualified technician.

Before turning on the radar, be sure
no one is near the antenna.

Prevent the potential risk of being
struck by the rotating antenna, which
can result in serious injury or death.

If water leaks into the equipment or
something is dropped into the
equipment, immediately turn off the
power at the switchboard.

Fire or electrical shock can result.

If the equipment is giving off smoke
or fire, immediately turn off the
power at the switchboard.

Fire or electrical shock can result.

If you feel the equipment is acting
abnormally or giving off strange
noises, immediately turn off the
power at the switchboard and
contact a FURUNO service techni­cian.

Do not disassemble or modify the
equipment.

Fire, electrical shock or serious injury
can result.

Make sure no rain or water splash
leaks into the equipment.

Fire or electrical shock can result if
water leaks into the equipment.

WARNING

WARNING

Do not operate the equipment with
wet hands.

Electrical shock can result.

Keep objects away from the open­type antenna unit, so as not to
impede rotation of the antenna.

Fire, electrical shock or serious injury
can result.

Use the proper fuse.

Use of the wrong fuse can cause fire or
damage the equipment.

The TT function is a valuable aid to
navigation. However, the navigator
must check all aids available to
avoid collision.

- The TT automatically tracks an
automatically or manually acquired
radar target and calculates its course
and speed, indicating them with a
vector. Since the data generated by
the TT depends on the selected radar
targets, the radar must be optimally
tuned for use with the TT, 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 sea and rain
clutter controls and the gain control so
that the target echoes do not dis­ appear from the radar screen.

Do not place liquid-filled containers
on or near the equipment.

Fire or electrical shock can result if a
liquid spills into the equipment.

SAFETY INSTRUCTIONS

CAUTION

CAUTIO

The plotting accuracy and response of this
TT 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 approx. 15-30 seconds for
the higher relative speed; approx. 30-60
seconds for the lower relative speed. The
following factors can affect accuracy:

- Echo intensity

- Radar transmission pulse length

- Radar bearing error

- Gyrocompass error

- Course change (own ship and targets)

Warning Label(s)

Warning label(s) is(are) attached to the
equipment. Do not remove the label(s). 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.

Signal Processing Functions

This radar has the signal processing functions described in the table below. All signal processing
functions are set with the picture preset feature.

Signal processing function Description Section

Interference rejector Suppress interference transmitted by other radars. Inter-

ference received simultaneously from many radars can
be difficult to reduce.

Echo stretch Enlarge target echoes, especially small echoes. Sup-

press interference, sea clutter and rain clutter before us­ing echo stretch, to prevent the enlargement of unwanted
echoes.

Echo averaging The radar samples echoes with each scan. Targets that

show a large change with each scan are judged as clutter
and are reduced to display only echoes from legitimate
targets.

Noise rejector Suppress white noise and increase the S/N ratio to im-

prove picture clarity.

Standards Used in this Manual

• Three types of Control Units are available: Radar Control Unit RCU-025 (radar controls with

trackball module), ECDIS Control Unit RCU-024 (alphabet keyboard, controls, trackball mod­ule) and Trackball Control Unit RCU-026 (trackball module only). Unless noted otherwise, “Con­trol Unit” refers to the RCU-025.

• The system can be operated with the controls of the Radar Control Unit, ECDIS Control Unit or

a trackball module. The descriptions in this manual use the trackball module.

• Unless noted otherwise, "click" means to push the left button on a trackball module.

• The keys and controls of the Radar Control Unit are shown in bold face; for example, the EN-

TER key.

• The buttons on the InstantAccess bar, Status bar and menu items are shown in brackets; for

example, the [TUNE] button.

• Context-sensitive menus are available with many buttons, and boxes and objects. Right-click

an item to display the related context-sensitive menu.

• This radar is available in three types of specifications: IMO, A, or B. This manual provides the

descriptions for the B type, of which some functions are not available with the IMO or A type.
See the menu tree in Appendix 1 for function availability.

• “C-MAP” means “C-MAP by Jeppesen”.

Virus Prevention

The ECDIS is not equipped with a virus checker. The ECDIS operates in real time; therefore, hav­ing a virus checker that periodically checks the equipment for viruses would increase the process­ing load, which can affect operation. However, you can avoid viruses by following the instructions
in this section.

When you update a chart

The PC and medium (USB flash memory, etc.) used to download and store an update for an ex­isting chart or a new chart may be infected with a virus. Check the PC and the medium for viruses
with a commercial virus checker - BEFORE you connect them to the ECDIS. Be sure the virus
checker contains the latest virus definition files.

Network connection

The ECDIS receives and displays information from various navigation equipment and radar via a
LAN. A PC and other equipment connected to a network can carry viruses. To prevent the intro­duction of a virus to the LAN, DO NOT connect the ECDIS or HUB to an external network, includ­ing other shipboard LAN.

Do not install 3rd party programs in the ECDIS

Programs installed via an external network can carry viruses that can cause the ECDIS to mal-

®

function. Do not install any Windows

software.

1.1 Units of the System

1.1.1 Radar Control Unit RCU-025

The Radar Control Unit RCU-025 consists of various controls and a trackball module
(trackball, scrollwheel and left and right buttons). The trackball module functions like
a PC mouse. The user rolls the trackball and operates the left and right buttons and
the scrollwheel to do various functions.

The RCU-025 has 28 direct access keys, five knob-type controls, two rotary encoders,
a power switch, a USB port, and a trackball module. The system can be operated with
the keys and controls or with the trackball module.

1.1.3 Processor Unit EC-3000

The Processor Unit is the heart of the chart system, and is mainly responsible for the
chart management, route planning and route navigation.

The Processor Unit has two power switches. The Mains switch controls the power
from the switchboard, and the Power switch controls the power to the chart radar sys­tem.

1. OPERATIONAL OVERVIEW

DVD
drive

Mains switch

Note 1: Do not operate the chart radar with a DVD or CD inserted in the DVD drive,
to prevent damage to the drive and media. Remove media from the drive after usage.
Insert media only to update charts. After completion of an update, remove the media
from its drive and store it in its case. Store media out of direct sunlight, in a place
where temperature and humidity are moderate and stable

Note 2: To keep the system stable, restart the unit at least once every two weeks.

Note 3: Close the lid of the DVD drive when the drive is not in use.

Power switch

1.2 How to Turn the System On/Off

Normally, leave the power switches at the front of the Processor Unit on and control
the power with the power switch on a Control Unit (RCU-025, RCU-026). The monitor
unit is powered independently.

How to power the system

Push the mains switch on the Processor Unit for the "I" position. Turn on the power
switch on the Processor Unit or a Control Unit. The start-up display appears on the
monitor.

After the power is applied, the program starts up and about one minute later the bear­ing scale appears. The radar then goes into three minutes of warm-up time to warm
the magnetron, which transmits radar pulses. The timer at the center of the screen
counts the time remaining for warm-up. When the timer shows 0:00, the indication
"ST-BY" appears at the screen center. The radar is now ready to transmit radar puls­es. In the stand-by condition, no radar pulses are transmitted and TT nor AIS is active.

The settings on the menus are stored in a non-volatile memory (hard disk) and are
preserved when the power is turned off.

1-5

1. OPERATIONAL OVERVIEW

Note: If the ambient temperature is less than 0°C (32°F) when the power is applied,
nothing appears on the display and the Status LED on the Control Unit flashes. This
is because the heater is warming the unit. The display appears in approx. two minutes.

How to power off the system

Press the power switch on the Processor Unit or a Control Unit. Push the Mains switch
for the "O" position.

Note: Provided that the radar was once in use with the transmitter tube (magnetron)
still warm, you can put the radar in transmit state without three minutes of warm-up. If
the Power switch was turned off by mistake or the like and you wish to restart the radar
promptly, turn on the Power switch not later than 10 seconds after power-off.

1.3 How to Adjust the Display Brilliance (FURUNO monitor)

The brilliance setting is defined according to the color palette setting. However, man­ual adjustment of the brilliance is also possible.

Note 1: The brilliance of the FURUNO monitor can only be adjusted from the Control
Unit. Use a serial cable for brilliance adjustment to make the connection between the
Processor Unit and the Control Unit.

Note 2: Improper brilliance may affect the visibility of information, especially on the
night display.

1.3.1 Manual brilliance adjustment

How to adjust the brilliance manually with the BRILL control

Operate the BRILL control to adjust brilliance. Turn it clockwise to increase the bril­liance; counterclockwise to decrease the brilliance. Watch the brilliance level indica­tion on the [BRILL] button (see the illustration below) to see the current brilliance level.

How to adjust the brilliance manually with the InstantAccess knob

1.6.2 How to operate the buttons, slider bars on the Status bar

The Status bar has three types of controls: toggle button, drop-down list button and
slider bar. You operate the buttons and bars with the trackball module.

Control type Example of control

Toggle button

A toggle button alternately selects one of two
functions assigned to the button. For example,
the [STBY TX] button toggles the radar between
stand-by and TX. The background color of the
[STBY TX] button momentarily changes to light­blue when switching from standby to TX.

Drop-down list button

A drop-down list button provides a list from which
to select an option related to the label on the but­ton. A drop-down list button is identified by a tri­angle on the button’s bottom-right corner. The
[Chart database] button, shown in the right figure,
is an example of a drop-down list button.

Click button to show
drop-down list.

OPERATION

2.1 How to Transmit

After the power is turned on and the magnetron has warmed,
"ST-BY" appears at the screen center, meaning the radar is
ready to transmit radar pulses. You can transmit by pushing
the STBY/TX key on the Control Unit, or clicking the [STBY
TX] button on the Status bar.

The radar is initially set to previously used range and pulse length. Other settings such
as brilliance levels, VRMs, EBLs and menu option selections are also set to previous
settings.

The STBY/TX key (or [STBY TX] button) toggles the radar between STBY and
TRANSMIT state. The antenna is stopped in stand-by and rotates in transmit. Set the
radar in standby when its use is not required, to conserve the life of the magnetron.

2.2 How to Tune the Radar Receiver

After the radar is transmitting, adjust the receiver to the exact frequency of the trans­mitter, automatically or manually. The current tuning method and tuning status is
shown at the top-left position.

Loss of gyrocompass signal

When the gyrocompass signal is lost, the Alert
“Gyro xxx COM1 Error” (xxx=a number be­tween 250 and 259 according to gyro no.) ap­pears in the [Alert] box. After all signals are lost,
the Alert 450 “Heading Sensor Not Available”
appears, the presentation mode becomes
head-up and all TT and AIS are erased. Check
the gyrocompass and select the presentation
mode with the MODE key or the Range/Pre­sentation mode box.

2.3.2 Description of presentation modes

Head-up mode

The head-up mode is a display in which the line
connecting 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.

The short line on the bearing scale is the north
marker, which indicates heading sensor north. A
failure of all the heading sensor inputs will cause
the heading readout to disappear, and the Alert 450 "Heading Sensor Not Available"
or "Gyro xxx COM1 Error" (a number between 250-259 according to gyro no.) appears
in the [Alert] box.

Course-up mode

The course-up mode is an azimuth stabilized dis­play in which a line connecting the center with the
top of the display indicates own ship's intended

line

course (namely, own ship's previous heading just
before this mode has been selected).

Target pips are painted at their measured dis­tances and in their directions relative to the in­tended course, which is maintained at the 0­degree position. The heading line moves in ac­cordance with ship's yawing and course change. This mode is useful for avoiding
smearing of the picture during course change.

Head-up TB (True Bearing) mode

Radar echoes are shown in the same way as in the head-up mode. The difference
from the normal head-up presentation lies in the orientation of the bearing scale. The
bearing scale is heading sensor stabilized. That is, it rotates in accordance with the
heading sensor signal, enabling you to know own ship's heading at a glance.

This mode is available when the radar is interfaced with a gyro heading sensor. If the
gyro heading sensor fails, the bearing scale returns to the state of head-up mode.

North-up mode

The north-up mode paints target pips at their mea­sured distances 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. Requires
heading signal.

If the compass fails, the presentation mode changes
to head-up and the north marker disappears. A failure
of the heading sensor input will cause the heading
readout to disappear, and the Alert 450 "Heading
Sensor Not Available" or "Gyro COM1 Error" (a number between 250-259 according
to gyro no.) appears in the [Alert] box.

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. In the sea stabilized TM without set and
drift inputs, the landmass can move on the screen. Note
that true motion is not available on the 96 nm or higher
range scale range scale. If COG and SOG (both over the
ground) are not available on the TM mode, enter the set
(tide direction) and drift (tide speed) manually referring to
a Tide Table.

2. RADAR, CHART RADAR OPERATION

If the position of the CCRP results in a part of the bearing scale not being distinguish­able, that part of the bearing scale is indicated with appropriate reduced detail.

A failure of the heading sensor input will cause the heading readout to disappear, and
the Alert 450 "Heading Sensor Not Available" or "Gyro COM1 Error" (a number be­tween 250-259 according to gyro no.) appears in the [Alert] box.

When own ship reaches a point corresponding to 50% 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 can also reset the own ship
symbol manually by pushing the CU/TM RESET key, or click the [CU/TM reset] button
on the InstantAccess bar.

2.6 How to Adjust the Sensitivity

The GAIN control (or [Gain] button) adjusts the sensitivity of the receiver. The proper
setting is such that the background noise is just visible on the screen. If you set up for
too little sensitivity, weak echoes may be missed. On the other hand excessive sensi­tivity yields too much background noise; strong targets may be missed because of the
poor contrast between desired echoes and the background noise on the display.

Adjust the gain so background noise is just visible on the screen.

How to adjust the sensitivity from the Control Unit

While monitoring the radar image and the gain slider bar, operate the GAIN control to
adjust the sensitivity.

How to adjust the sensitivity from the trackball module

For coarse adjustment, put the cursor within the slider bar area then push the left

button. For fine adjustment, put the cursor at the end of the slider bar then roll the
trackball while pushing and holding down the left button. Release the button to finish.

Put cursor on slider bar and push and
hold left button. Drag cursor to new
location then release left button.

2.7 How to Suppress Sea Clutter

Echoes from waves cover the central part of the display with random signals known
as sea clutter. The higher the waves, and the higher the antenna above the water, the
further the clutter will extend. When sea clutter masks the picture, suppress it with the
A/C SEA control (or [SEA] on the Status bar), either manually or automatically.

When both sea clutter and rain clutter are reduced, the sensitivity is decreased more
than when only one is adjusted. For that reason adjust them carefully.

The echo average is useful for reducing reflections from the sea surface. However,
high-speed targets are harder to detect than stationary ones when the echo average
is active.

2.7.1 How to reduce sea clutter automatically

Auto A/C SEA allows for fine-tuning of the A/C SEA circuit, within ±20 dB. Accordingly,
with the bar reading set to 100, gain is not lowered to minimum as with manual A/C
SEA on close-in ranges. Further, the auto A/C SEA level is low because the average
value of the original input echo is low in areas where there are no sea surface reflec­tions. For example, when the ship is alongside a quay and the radar picture shows
echoes from both land and sea, you can observe the size of echoes because the STC
curve is different depending size of echoes.

To get automatic adjustment of sea clutter, do one of the following:

Control Unit: Push the A/C SEA control to display
[AUTO] on the [SEA] mode indication on the Status
bar.

Trackball module: Click the [SEA] mode indication
to display [AUTO].

2.7.2 How to reduce sea clutter manually

The A/C SEA control reduces the ampli­fication of echoes at short ranges (where
clutter is the greatest) and progressively
increases amplification as the range in­creases, so amplification will be normal
at those ranges where there is no sea
clutter.

The proper setting of the A/C SEA
should be 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.

Be careful not to remove all sea clutter, because you may erase weak echoes. Fur­ther, the possibility of losing weak echoes is greater when you use both A/C SEA and
A/C RAIN to reduce clutter.

To reduce sea clutter manually, do one of the following:

2. RADAR, CHART RADAR OPERATION

Control Unit: Push the A/C SEA control to display [MAN] on the [SEA] mode indica­tion on the Status bar. Rotate the A/C SEA control to adjust the sea clutter.

Trackball module: Click the [SEA] mode indication on the Status bar to display
[MAN]. For coarse adjustment, put the cursor within the slider bar area then push the
left button. For fine adjustment, put the cursor at the end of the slider bar then roll the
trackball while pushing and holding down the left button. Release the button to finish.

2.8 How to Suppress Rain Clutter

The vertical beam width 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 A/C
RAIN control to split up these unwanted echoes into a speckled pattern, making rec­ognition of solid targets easier.

Be careful not to remove all rain clutter, because you can erase weak echoes. Further,
the possibility of losing weak echoes is greater when you use both A/C RAIN and A/C
SEA to reduce clutter.

Note 1: When both sea clutter and rain clutter are reduced the sensitivity is decreased
more than when only one is adjusted. For that reason adjust them carefully.

Note 2: The echo average (see 2.16) is useful for reducing reflections from the sea
surface. However, high-speed targets are harder to detect than stationary ones when
the echo average is active.

2.8.1 How to reduce rain clutter automatically

Control Unit: Push the RAIN control to display

[AUTO1], [AUTO2], [AUTO3] or [AUTO4] on RAIN
mode indication on the Status bar. The higher the
number the greater the degree of rain clutter reduc­tion.

Trackball module: Click the [RAIN] mode indication
on the Status bar to display [AUTO1], [AUTO2],
[AUTO3] or [AUTO4]. The higher the number the
greater the degree of rain clutter reduction.

2.8.2 How to reduce rain clutter manually

Control Unit: Push the RAIN control to display [MAN] on the [RAIN] mode indication

on the Status bar. While watching the radar picture, adjust the RAIN control to reduce
the clutter.

Trackball module: Click the [RAIN] mode indication on the Status bar to show [MAN].
For coarse adjustment, put the cursor within the slider bar area then push the left but­ton. For fine adjustment, put the cursor at the end of the slider bar then roll the trackball
while pushing and holding down the left button. Release the button to finish.

Note: The detection range is reduced when the RAIN is used to show targets in rain.
Generally, the amount of rain, TX pulse length and TX frequency are factors in deter­mining how the detection range is affected. The figures shown below illustrate this oc­currence.

4 mm/h rain (long pulse): approx 2.6 nm
16 mm/h rain (long pulse): approx 0.9 nm

2.9 How to Measure the Range to a Target

The range to a target may be measured three ways: with the fixed range rings, with
the cursor, or with the VRM.

Use the range rings to obtain a rough estimate of the range to a target. They are the
concentric solid circles about own ship, or the sweep origin. The number of rings is
automatically determined by the selected range scale and their interval is displayed in
the Range/Presentation mode box at the top-left position on 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.

The range rings can be turned on/off with [RANGE RING] on the [NAV TOOL] menu.

2.9.1 How to measure the range by using a VRM

There are two VRMs, No. 1 and No. 2, which appear as dashed rings so that you can
distinguish them from the fixed range rings. The two VRMs can be distinguished from
each other by the different lengths of their dashes; the dashes on the No. 2 VRM are
longer.

2.10 How to Measure the Bearing to a Target

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 from the own
ship position up to the circumference of the radar picture. The two EBLs can be dis­tinguished from each other by the different lengths of their dashes; the dashes on the
No. 2 EBL are longer.

Each EBL carries a range marker, or a short line crossing the EBL at right angles. Its
distance from the EBL origin is indicated at the VRM readout whether or not the cor­responding VRM is displayed. The range marker changes its position along the EBL
with the rotation of the VRM control. To operate this marker, rotate the VRM rotary
control on the Control Unit, or put the cursor in the applicable VRM box and roll the
scrollwheel.

2.11 Collision Assessment by Offset EBL

The origin of the EBL can be placed anywhere with the trackball to enable measure­ment of range and bearing between two targets. This function is also useful for as­sessment of the potential risk of collision. It is possible to read CPA (Closest Point of
Approach) by using a VRM as shown in Figure (a) on the next page. If the EBL passes
through the sweep origin (own ship) as illustrated in Figure (b), the target ship is on a
collision course.

2.11.1 How to assess risk of collision

How to assess risk of collision from the Control Unit

1. Press the EBL1 or EBL2 key to activate an EBL.

2. Put the cursor on a target that appears as a threatening target (A in the figure on
the next page).

3. Press the EBL OFFSET key to shift the EBL origin to the cursor location.

4. Wait approx. three minutes. Operate the EBL rotary control to bisect the target at
the new position (A'). The EBL indication shows the target ship's course, which
may be true or relative depending on the EBL bearing reference setting.

5. If relative motion is selected, it is also possible to read CPA by using a VRM as
shown in the left figure on the next page. If the EBL passes through the sweep
origin (own ship) as illustrated in the right figure on the next page, the target ship
is on a collision course.

To return the EBL origin to the center of the screen, press the EBL OFFSET key.

2.13 How to Off-center the Display

Own ship position, or sweep origin, can be displaced to expand the view field without
switching to a larger range scale. The sweep origin can be off-centered to the cursor
position, but not more than 75% of the range in use; if the cursor is set beyond 75%
of the range scale, the sweep origin will be off-centered to the point of 75% of the limit.

This feature is available on the ranges between 0.125 and 48 NM and any presenta­tion mode other than true motion.

If the position of the CCRP results in a part of the bearing scale not being distinguish­able, that part of the bearing scale is indicated with appropriate reduced detail.

Off-centered display

How to off-center the display from the Control Unit

1. Put the cursor on the position within the display area where you want to move the
sweep origin.

2. Press the OFF CENTER key to move the sweep origin to the cursor position.

To cancel off-centering, press the OFF CENTER key again.

How to off-center the display from the context-sensitive menu

1. Put the cursor where you want to off-center the display then right-click to show the
context-sensitive menu.

2. Select [Off Center].

3. Push the left button. Then, the sweep origin is off-centered to the cursor position.

To cancel the off-center display, put the cursor on the sweep origin and right-click.

If you cannot cancel off-center…

When the conditions shown below are met, offcenter cannot be cancelled. This is be­cause the radar antenna position is located at a position greater than 75% of the ef­fective radar display.

• Own ship marker is large.

• The distance between the antenna position and the conning position is large.

• Short-distance display range.

To cancel the off-center in the above-mentioned conditions, first select a larger range,
then cancel the off-center.

2.14 Interference Rejector

Mutual radar interference may occur in the vicinity of an­other shipborne radar operating in the same frequency
band. It is seen on the screen as a number of bright
spikes either in irregular 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 interference.

The interference rejector is a kind of signal correlation
circuit. It compares the received signals over succes­sive transmissions and reduces randomly occurring sig­nals. There are three levels of interference rejection depending on the number of
transmissions that are correlated.

Click the [IR] button on the InstantAccess bar then click desired rejection level. The
higher the number the greater the degree of interference rejection.

IR button

2.15 Echo Stretch

The echo stretch feature enlarges targets in the range and bearing directions to make
them easier to see, and it is available on any range. There are three levels of echo
stretch, 1, 2 and 3. The higher the number the greater the amount of stretching.

The echo stretch magnifies not only small target pips but also returns from the sea sur­face, rain and radar interference. For this reason, suppress those types of interference
before activating the echo stretch.

Click the [ES] button on the InstantAccess bar then click desired echo stretch level.

ES button

2.16 Echo Averaging

The echo averaging feature, which requires heading, position and speed data, effec­tively reduces sea clutter. Echoes received from stable targets such as ships appear
on the screen at almost the same position every rotation of the antenna. On the other
hand, unstable echoes such as sea clutter appear at random positions.

To distinguish real target echoes from sea clutter, echoes are averaged over succes­sive picture frames. If an echo is solid and stable over successive frames, it is present­ed in its normal intensity. Sea clutter is averaged over successive scans and its
brilliance reduced, making it easier to discriminate real targets from sea clutter.

Echo averaging uses scan-to-scan signal correlation technique based on the true mo­tion over the ground of each target. Thus, small stationary targets such as buoys will
be shown while reducing random echoes such as sea clutter. True echo averaging is
not however effective for picking up small targets running at high speeds over the
ground.

Note 1: With echo average active it is harder to detect high-speed targets than sta­tionary ones.

2. RADAR, CHART RADAR OPERATION

Note 2: Do not use echo averaging under heavy pitching and rolling; loss of targets
can result.

Before using the echo averaging function, reduce sea clutter with the A/C SEA control.
Leave a little sea clutter on the screen so as not to erase weak targets. Then, do as
follows:

Click the [EAV] button on the InstantAccess bar then click desired setting.

OFF: Echo averaging OFF.
1, 2: Detects targets hidden in sea clutter. "2" is more effective than "1" in detecting

targets hidden in strong sea clutter. However, "1" is more effective than "2" in display­ing high-speed targets. Select the setting best suited to your objective.
3: Stably displays unstable targets; distinguishes high-speed craft from sea clutter.

2.23 How to Preset Controls for Specific Navigation Purpose

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 function keys to provide optimum settings for often­encountered situations.

The radar's internal computer offers several picture preset options to be assigned to
each function key for your specific navigating requirements. For instance, one of the
presets is labelled HARD RAIN, and is designed to be used in heavy rain.

Two user-programmable presets are also provided (labeled CUSTOM1, CUSTOM2),
so that you can have the radar automatically adjusted to those conditions that are not
covered by the provided setup options.

Below are the preset options provided with this radar.

Label Description Label Description

OCEAN Optimum setting for long

range detection, on a range
scale of 6 nm or larger.

CANAL Optimum setting for operating

in a canal.

BERTHING Optimum setting when

berthing.

CONGESTION Optimum setting for short

range navigation (for exam­ple, a harbor) using a range
scale of 1.5 nm or less.

Each picture option defines a combination of several radar settings for achieving op­timum setup for a particular navigating situation. These include interference rejector,
echo stretch, echo average, noise rejector, automatic anti-sea and anti-rain clutters,
video contrast, pulse length and sea and radar conditions.

ROUGH SEA Optimum setting for operation

in rough seas.

HARD RAIN Optimum setting for rough

weather or heavy rain.

CUSTOM1 User-defined custom

settings.

CUSTOM2 User-defined custom

settings.

2-29

2. RADAR, CHART RADAR OPERATION

Adjusting these features from the [CUSTOMIZE ECHO] menu changes the original
function key settings. To restore the original settings for a particular customize option,
it is necessary to select the default setting. For this reason, we recommended that you
use the user-programmable presets when frequent adjustment of the radar image is
necessary.

Item Description

1 DEPTH Selects unit of depth measurement, or turn depth indica-

tion OFF.

2 DEPTH GRAPH SCALE Selects depth scale range. The depth for the last 30 min-

utes is plotted with a yellow line. The [AUTO] setting auto­matically adjusts the scale according to depth.

3 DEPTH MARK Selects the depth at which to show the depth mark.

4 CURRENT Turns the current (tide) display ON (current relative to

North) or OFF.

5 WIND Selects the unit of wind speed measurement.

6 WIND STAB Selects Wind vector format, among three choices:

APPARENT: Apparent wind measured by wind meter,
with ship's bow as reference.
NORTH: Apparent wind minus ship's movement, with
North as reference
THEORETICAL: Apparent wind minus ship's movement,
with ship's bow as reference.

7 TEMPERATURE Turns water temperature indication ON or OFF and se-

lects the unit of measurement.

8 WPT DATA Turns waypoint data OFF, or selects waypoint data refer-

ence, true or relative.

2-38

Note: Appropriate sensors are required to display any data. The wind vector shows a

direction from which the wind blows in, relative to own ship heading, and is labeled "T
*." Wind velocity is a true wind speed as a result of compensating for own ship's speed
and orientation. Ocean current (tide) is shown relative to bow in head-up, cursor gyro
and course-up, and reference to North in north-up and true motion.

2.28 Interswitch

The interswitch uses a network to transfer multiple radar signals to the monitor units
connected in the network. A master/slave relation can be set for a single radar signal
and that signal can be shown on multiple displays. Up to four antennas and four dis­play units can be connected. Set the radar display and antenna groups from the [An­tenna] button on the Status bar.

When you switch to a different antenna, the heading skew and timing adjustment (set
at installation) for that antenna are automatically applied.

The [Antenna] button on the Status bar shows current antenna selection.

Antenna selection considerations

• An antenna unit cannot be controlled from multiple display units. Select one Master
display unit for one antenna unit. If two antenna units are set as masters, the display
last-set as master becomes the master and all other displays are automatically
changed to slave.

• An antenna unit without a Master display cannot be selected on the sub display
units. If there is no antenna unit set as master, the lowest number display is auto­matically set as master.

• Radar functions are controlled independently, dependently or commonly depending
on selection as Master or Slave.

• If the Alert 750 “EXT Radar COM Error” appears, do one of the following as appli­cable:

• If only your antenna is not displayed on the [ANT SELECT] display, the LAN line

in the Processor Unit may be faulty. In this case, use the standalone mode.

• If the antenna that was in use does not appear on the [ANT SELECT] display, the

LAN line in other Processor Unit may be faulty. In this case, see the preceding
page for how to select a different antenna unit.

• When the Network fails, the Interswitch does not work, but standalone operation is

How to check radar performance

The range scale is automatically set to 24 nm. The radar screen will show one or two
arcs. If the radar transmitter and receiver are in good working order in as much as the
original state when the monitor was turned on, the innermost arc should appear be­tween 13.5 and 18.5 nm. The performance monitor can observe a total of 10 dB loss
in the transmitter and receiver.

Note: The lengths and location of the arcs may vary according to the direction in which
the antenna unit is installed. Judge the strength of the echo that appears within 60°
from arc location to confirm if the radar is working properly or not.

Turn off the performance monitor when finished.
