SAFETY INSTRUCTIONS

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 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.

SAFETY INSTRUCTIONS

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 warning 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.

WARNING

Use the proper fuse.

Use of a wrong fuse can result in damage to the equipment or cause fire.

Keep heater away from equipment.

Heat can alter equipment shape and melt the power cord, which can cause fire or electrical shock.

Do not place liquid-filled containers near the equipment.

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

Do not operate the equipment with wet hands.

Electrical shock can result.

Before servicing the radar, turn off the appropriate external breaker.

Power is not removed from the radar simply by turning off its power switch.

Do not disassemble or modify the equipment.

Fire, electrical shock or serious injury can result.

Immediately turn off the power at the ship's mains switchboard if water leaks into the equipment or the equipment is emitting smoke or fire.

Continued use can cause fatal damage to the equipment.

SAFETY INSTRUCTIONS

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.

• This 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 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 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, AIS and video plotter are intended for reference only.

Refer to official nautical charts for detailed and up-to-date information.

Precautions for high speed targets

Assume your ship is making 40 kt and a target ship is approaching at 49 kt right toward you. Then the relative speed is 80 kt. With the antenna rotating at 42 rpm, the target blip appears jumping to a new location 59 m nearer. This jump corresponds to 19 mm on the display using the 0.25 nm range scale. On such a short range you may lose the track of a target in the midst of sea clutter, random noise or other targets. Use one step larger range scale.

ARPA can fail to track a target when the relative speed exceeds 100 kt.

1 RADAR OPERATION

1.1 Turning on the Power

The [POWER] switch is located at the left corner of the control unit. Open the power switch cover and press the switch to turn on the radar system. To turn off the radar, press the switch again. The screen shows the bearing scale and digital timer approximately 30 seconds after power-on. The three minutes of warm-up time. During this period the magnetron (transmitter tube) is warmed for transmission. When the timer has reached 0:00, the indication “ST-BY” appears at the screen center, meaning the radar is now ready to transmit pulses.

In the stand-by condition, markers, rings, map, charts, etc. are not shown. Further, ARP is cancelled and the AIS display is erased.

In warm-up and stand-by condition, ON TIME and TX TIME counts in hours and tenths of hour appear at the screen center.

timer counts

down

1.2 Transmitter ON

After the power is turned on and the magnetron has warmed up, ST-BY appears at the screen center, meaning the radar is ready to transmit radar pulses. You may transmit by pressing the [STBY/TX] key on the full keyboard or roll the trackball to choose the TX STBY box at the bottom left corner of the display and then push the left button (above the trackball). The label at the left-hand side of the guidance box at the bottom right corner of the screen changes from TX to STBY.

1. RADAR OPERATION

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 TX STBY box) toggles the radar between STBY and TRANSMIT status. The antenna stops in stand-by and rotates in transmit. The magnetron ages with time resulting in a reduction of output power. Therefore, it is highly recommended that the radar be set to stand-by when not used for an extended period of time.

Quick start

Provided that the radar was once in use with the transmitter tube (magnetron) still warm, you can turn the radar into TRANSMIT condition without three minutes of warm-up. If the [POWER] switch has been 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.

1.5 Operation Usin g the On-Screen Boxes

All radar functions can be accessed by using the trackball alone. This is done by choosing the appropriate on-screen box with the trackball and operating the trackball module to choose item and option. (See paragraph 1.9 for location of all on-screen boxes.) On-screen boxes come in two varieties: Function selection and function selection w/pop-up menu. On-screen boxes of the latter type have “►” at the right side of their boxes, as in the MARK box shown below.

To operate the radar using on-screen boxes, do the following:

1. Roll the trackball to place the trackball marker inside the box desired.

Note: The trackball marker changes its configuration according to its location.

It is an arrow when placed outside the effective display and a cursor (+) when inside the effective display. See the illustration on the next page for further details.

For example, choose the MARK box, which is at the bottom left corner.

MARK box

When a box is correctly selected, its color changes from green to yellow (default colors) and the guidance box at the bottom right corner shows operational guidance. The operational guidance shows the function of the left and right buttons, with a diagonal line separating the information. For the MARK box, for example, the operational guidance is “MARK SELECT / MARK MENU.” In this case you would push the left button to choose a mark or push the right button to open the MARK menu.

Trackball marker location and guidance box indication

The trackball marker is either a cursor (+) or an arrow ( ) depending on whether it is within or outside the display area, respectively. Further, the indication in the guidance box changes according to trackball marker location.

Trackball marker is out of effective display area (incl. text area) and not selecting a box: The trackball marker is an arrow

Guidance box reads "JUMP CURSOR / DISP MENU." Push the left button to choose the on-screen box closest to the arrow or push the right button to display the MAIN menu.

To choose boxes successively, push the wheel when the guidance box reads as above. Then, the nearest box is selected and marked with the double-ended arrow ( ) and the guidance box reads "JUMP FORWARD / JUMP BACKWARD." Hit the left button to go to the box below or adjacent to the currently selected box or hit the right button to go to the box above or adjacent to the currently selected box. Continue pushing a button to choose boxes successively. This is convenient for operation under heavy pitching and rolling. To cancel this feature, push the wheel when the guidance box reads as above.

Guidance box reads "TARGET DATA & ACQ / CURSOR MENU." In this condition you may access cursor-operated

Trackball marker is within effective display area: The trackball marker is a cursor

functions, by hitting the left button for direct selection of function or the right button to choose desired functions from the CURSOR menu. For further details about the CURSOR menu, see paragraph 1.6.

2. Push the left button (or roll the wheel depending on the box) until the desired

option is displayed in the box.

Note: When you chose an on-screen box’s option by rolling the wheel, the

box and its contents turn red. This simply indicates that the chosen setting is different from the currently active setting. To change the setting, push the wheel or the left button. If neither the wheel nor the left button is pushed within about 30 seconds after operating the wheel, the previous setting is automatically restored.

Relative Motion (RM)

Head-up: Unstabilized Head-up TB: Head-up with compass-stabilized bearing scale (True Bearing)

where the bearing scale rotates with the compass reading. Course-up: Compass-stabilized relative to ship’s orientation at the time of selecting course-up. North-up: Compass-stabilized with reference to north

True Motion (TM)

North-up: Ground or sea stabilized with compass and speed inputs

1.12.1 Choosing presentation mode

By keyboard

Press the [MODE] key consecutively to choose presentation mode desired. The PRESENTATION MODE box shows the current presentation mode. (See the illustration below.)

By trackball

1. Roll the trackball to place the arrow in the PRESENTATION MODE box at

the top left corner of the screen.

2. Push the left button to choose mode desired.

Loss of gyrocompass signal

When the compass signal is lost, “HEADING SET” appears in red at the gyro readout, the presentation mode automatically becomes head-up, all ARP and AIS targets and map or chart are erased. After restoring the compass signal, choose the presentation mode with the [MODE] key or the PRESENTATION MODE box.

1.12.2 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.

A short line on the bearing scale is the north marker indicating heading sensor north. A failure of the heading sensor input will cause the north marker to disappear and the readout to show ***.*° and the message HDG SIG MISSING appears in red at the lower-right corner of the screen.

1. RADAR OPERATION

North Marker

Note: When display is off-centered, the heading mark appears at 000 degrees.

Head-up mode

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 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 0-degree position. The heading line moves in accordance with ship’s yawing and course change. This mode is useful to avoid smearing of picture during course change.

1-19

Page 44

1. RADAR OPERATION

Head-up TB (True Bearing) mode

Radar echoes are shown in the same way as in the head-up mode. The difference from 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. Also, the HDG indication shows ***.*°. And the message HDG SIG MISSING appears in red at the lower-right corner of the screen.

1. RADAR OPERATION

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 72 nm (non-IMO type only) or 96 nm range scale. If COG and SOG (both over the ground) are not available on TM mode, enter the set (tide direction) and drift (tide speed) manually referring to the Tide Table.

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 may also reset the own ship symbol manually by pressing the [CU/TM RESET] key, or roll the trackball to choose the CU/TM RESET box at the bottom right corner of the display and then push the left button.

If the heading sensor fails, the mode is changed to the head-up and the north marker disappears. The HDG readout shows ***.*° and the message HDG SIG MISSING appears in red at the lower-right corner of the screen.

1.16 Adjusting the Sensitivity

The gain control 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.

To adjust receiver sensitivity, adjust the gain control so background noise is just

visible on the screen.

By keyboard

While monitoring the gain level indicator at the top of the screen, operate the [GAIN] control to adjust the sensitivity.

1.17 Suppressing 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 by the A/C SEA control, either manually or automatically.

2. Push the left button to display SEA AUTO or SEA MAN as appropriate.

1.17.2 Automatic adjustment by the A/C SEA control

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.

Note: The auto A/C function can erase weak target echoes. Adjust the control

carefully, watching the display.

By keyboard

1. Choose SEA AUTO following the procedure in paragraph 1.17.1.

2. While observing the A/C SEA level indicator, adjust the A/C SEA with the [A/C

SEA] control. 100 levels are available.

1.17.3 Manual adjustment of A/C SEA

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.

1.18.2 Adjusting A/C RAIN

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.

1.19 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 suppresses randomly occurring signals. There are three levels of interference rejection depending on the number of transmissions that are correlated.

1.20 Measuring the Range

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

Use the fixed 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 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.

1.22 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 any 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 below (Figure (a)). If the EBL passes through the sweep origin (own ship) as illustrated (Figure (b)), the target ship is on a collision course.

1.22.1 How to assess risk of collision by the offset EBL

By keyboard

1. Press the [EBL ON] key to display or activate an EBL (No. 1 or No. 2).

2. Place the cursor (+) on a target appearing as threatening (A in the illustrated example on the next page) by operating the trackball.

3. Press the [EBL OFFSET] key, and the origin of the active EBL shifts to the cursor position. Press the [EBL OFFSET key] again to anchor the EBL origin.

4. After waiting for a few minutes (at least 3 minutes), operate the EBL rotary control until the EBL bisects the target at the new position (A'). The EBL readout shows the target ship's course, which may be true or relative depending on the EBL bearing reference setting.

Note: If relative motion is selected, it is also possible to read CPA by using a

VRM as shown in left-hand figure at the top of the next page. If the EBL passes through the sweep origin (own ship) as illustrated in the right-hand figure at the top of then next page, the target ship is on a collision course.

5. To return the EBL origin to the own ship's position, press the [EBL OFFSET] key twice.

1.24 Setting a Target Alarm

The target alarm serves to alert the navigator to targets (ships, landmasses, etc.) entering a set area, with audible and visual alarms.

The guard alarm zone has a fixed width of 0.5 nm in the radial direction (depth) and is adjustable from 3.0 to

6.0 nm (guard zone 1) and any distance (guard zone 2). On the Non-IMO radar the boundaries can be set at any distance. On any radar type the sector of the zone can be set from 0 to 360 degrees in any direction.

1.24.1 How to set a target alarm zone

The procedure which follows shows how to set a target alarm zone using the figure below as an example.

1. Roll the trackball to choose the ALARM1 or ALARM2 box, whichever alarm you wish to set.

1. RADAR OPERATION

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. RADAR OPERATION

Note 1: 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.”

Note 2: Two target alarm zones may be set. Note however that the 2

alarm zone is available only when the 1

Note 3: When the target alarm zone is not within the range in use the indication

UP RNG appears to the right of the ALARM box. In this case choose a range which will display the target alarm zone.

1.24.2 Acknowledging the target alarm

A target in the target alarm zone produces both visual (flashing) and audible (beep) alarms. To silence the audible alarm, press the [ALARM ACK] key on the full keyboard or choose the appropriate ALARM box and then push the left button. The ALARM box shows “ALARMx ACK.” This will deactivate the audible alarm but will not stop the flashing of the offending target. To reactivate the audible alarm, press the [ALARM ACK] key again or choose the ALARM box and then push the left button. (When an external buzzer is connected, the audible alarm does not stop until the alarm zone itself is deactivated.) The ALARM box shows “ALARMx WORK.”

1.24.3 Deactivating a target alarm

target alarm zone is active.

1.25 Off-Centering 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 not available on the 72 nm (Non-IMO type only) or 96 nm range scale nor in the true motion mode.

To off-center the radar picture, do the following:

By keyboard

1. Roll the trackball to place the cursor at a position where you wish to move the sweep origin.

2. Press the [OFF CENTER] key. Then, the sweep origin is off-centered to the cursor position.

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

1.27 Echo Averaging

The echo average feature effectively suppresses 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, 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.

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 suppressing random echoes such as sea clutter. True echo average is not however effective for picking up small targets running at high speeds over the ground.

Note 1: Do not use the echo average function under heavy pitching and rolling;

loss of target detection can result.

Note 2: Echo average can be used without a heading sensor. For further details,

contact your dealer.

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. Roll the trackball to choose the PICTURE box at the left side of the display.

2. Push the right button to show the PICTURE menu.

3. Roll the wheel to choose 3 ECHO AVERAGE and then push the wheel or the left button.

4. Roll the wheel to choose OFF, 1, 2 or 3 as appropriate and then push the wheel or the left button.

1.28 Target Trails

The trails of the radar echoes of targets may be displ ayed in the form of synthet ic afterglow. Target trails are chosen either r elative or true and may be sea or ground stabilized. True motion trails require a compass signal and own ship speed input.

1.28.1 True or relati ve tr ails

You may display ec ho trails in true or relative moti on ( only true trai l on TM). Relative tr ails show relative movements betw een targets and own ship. True motion tr ails require a gy r oc om pass signal and own ship speed input to cancel out own s hip's movement and present true target movem ents in accordance wit h their over-the-ground s peeds and cours es .

1.33 Automatic Picture Setup According to 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 often encountered situations.

The radar's internal computer offers several picture setup options to be assigned to each function key for your specific navigating requirements. For instance, one of the functions is assigned the buoy detecting function and labeled SHIP on the on the PICTURE box. By choosing SHIP, the radar will be instantly set for optimum detection of ships.

Four user-programmable setups are also provided (labeled PICTURE1-PICTURE4), so that you may have the radar automatically adjusted to those conditions which are not covered by the provided setup options.

Below are the preset picture setup options provided with this radar.

Picture setup options description

Label Description Label Description

NEAR Optimum setting for short range

detection using a range scale of 3

nm or less on calm seas NEAR BUOY

ROUGH SEA HARBOR Optimum setting for short range

Optimum setting for detecting

navigation buoys, small vessels and

other small surface objects at close

range

Optimum setting for rough weather

or heavy rain

navigation in a harbor area using a

range scale of 1.5 nm or less

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

Adjusting these features from the PICTURE menu changes the original function key settings. To restore the original settings for a particular picture setup option, it is necessary to choose the default setting. For this reason, we recommended that you use the user-programmable function sets when frequent adjustment of the radar picture is necessary.

FAR Optimum setting for long range

SHIP Optimum setting for detecting

COAST For coastal navigation using a
