WARNINWARNING

CAUTIONCAUTION

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 TT 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.

The plotting accuracy and response of this TT meets IMO standards. Tracking accuracy is affected by the following:

The data generated by TT, AIS and video plotter are intended for reference only.

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 target tracking and pertinent vector calculation accuracy is influenced by the following:

- Echo intensity

- The range measurement accuracy; characterized by both random and biased measurement errors.

- The angular measurement accuracy; characterized by beam shape, target glint and bias errors.

- Radar transmission pulsewidth

- Gyrocompass heading error

- Speed log error

- Curent and wind (set & drift)

- Course change (own ship and target)

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

DANGER

Electrical shock hazard. Turn off power before servicing.

Advanced fishing specifications

The following radar plotter features will be available by updating to the software for advanced fishing specifications and installing the RP board to the processor unit. Consult your local dealer regarding the software update and RP board installation.

• A variety of plotter-related functions. (Memory capacity increase for own and other ship’s track, ship’s track color customize function, mark/line function, memory capacity increase for origin mark, origin mark list, etc.)

• TT/AIS symbol customize function.

• Enhanced dynamic range for a more complete EAV (Echo Average) function.

• Compatible with the RCU-031 control unit that is specially designed for fisheries.

For details about advanced fishing specifications, see the operator’s manual (OME-36521).

Signal processing functions

This radar has the signal processing functions listed in the table below.

Function Description Reference

Interference rejector Suppresses interference by other radars.

Interference received simultaneously from multiple radars may be difficult to reduce.

Echo stretch Enlarges target echoes, especially small echoes.

Suppress interference, sea clutter and rain clutter before using echo stretch, to prevent 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.

Automatic clutter elimination Discriminates clutter from the radar echo, then reduc-

es the clutter automatically.

Noise rejector Reduces white noise then improves the on-screen

S/N ratio by processing the weighted moving average filter for the received echoes in the range direction. Use this function with caution. Weak target echoes may disappear from the screen or the range resolution may worsen.

1. OPERATIONAL OVERVIEW

1.2 How to Turn the Radar On/Off

The power button ( ) is located at the top-left corner of the RCU-014 and RCU-015 Control Units.

Note: The RCU-016 Control Unit has no power button. To turn the power on or off when using a RCU-016 Control Unit, use the power button on the RCU-014/RCU-015.

To turn the power on

The LED to the left of the power button lights up (green color) and the system begins

the startup process. The indication "Initializing......" appears at the center of the screen.

When the startup process is complete, the system begins warm-up procedures to prepare the magnetron for transmission. The warm-up can take up to three minutes. During the warm-up, indications for total on-time (magnetron on-time since installation) and total transmission time (since installation) appear below the warm-up countdown timer. These indications are also displayed when the radar is in standby mode. When the warm-up process is complete, the radar goes into standby (STBY) mode and the indication "RADAR STBY" (IMO-types) or "STBY" (A/B/R/W-types) appears. This indication also appears whenever the equipment is in STBY mode.

Note 1: For B/W-types with Radar Plotter functionality, the “STBY” indication appears only once, when the equipment is turned on. Note 2: For B/W-types with Radar Plotter functionality, the numerals on the heading dial (outer-most range ring) are not shown and the TT function is inactive while in standby (STBY) mode. Note 3: Do not turn on the power directly after it has been turned off. Wait several seconds before you reapply the power, to be sure the radar starts up properly.

To turn the power off

Note: Solid state radars do not have a magnetron, therefore they have no warming period.

, open the power switch cover, then press the power button.

1.3 How to Adjust the Brilliance

The screen brilliance (brightness) for monitors can be adjusted as shown below.

Note: The following procedure applies only to monitors supplied by FURUNO for this system. For other monitors, see the monitor operator’s manual to adjust the brilliance.

Brilliance adjustment from the Control Unit (RCU-014)

Rotate the BRILL knob clockwise to increase the brilliance (brighter), or rotate the BRILL knob counter-clockwise to reduce the brilliance (darker).

Brilliance adjustment from the on-screen box

Select the [BRILL] box, the spin the scrollwheel on the Control Unit upwards to reduce the brilliance (darker) or downwards to increase the brilliance (brighter).

Note: The above scrollwheel operation is based on default settings for [2 MOUSE WHEEL DIR]. See section 1.10.

Notes on speed input

It should be noted that in determining a target's aspect by radar, the calculation of its true track is dependent on the choice and accuracy of the own ship's course and speed input. A ground-stabilized target plot may accurately calculate the ground track of the target, but the target's heading may be significantly different from its track when experiencing set, drift or leeway. Similarly, a sea stabilized target plot may be inaccurate when own ship and the target, are experiencing different rates of set, drift or leeway.

• IMO Resolution A.823(19) for TT recommends that a speed log to be interfaced with

a TT should be capable of providing through-the-water speed (forward speed).

• Be sure not to select a [LOG] option when a speed log is not connected. If the log

signal is not provided, the ship speed readout at the top of the screen will be blank. In the event of a log error, enter speed manually.

• If a speed log is selected as the data source and there is no signal present for 30

seconds, the [SPD] is shown as "*.* kn" and the label "LOST LOG(BT) SIG" or "LOST LOG(WT) SIG" in yellow-orange appears and the alert buzzer sounds.

• When the speed input in use is interrupted or lost, the system automatically chang-

es to another speed input (stabilization reference) and shows the "SPD SOURCE CHG" indication.

• On IMO-type radars with AIS in use, [MANUAL] and [REF] are shown in gray to in-

dicate they are not available for selection.

• A single-axis water log cannot measure speed when the wind is coming from the

leeway direction.

• When [ECDIS] is selected as the speed data source and communication with the

ECDIS is interrupted or lost for 30 seconds, the Alert "LOST ECDIS COM" is released.

• When speed stabilization is changed at the ECDIS and [ECDIS] is selected as the

speed data source, the "SPD SOURCE CHG" indication appears.

1.12.2 Manual speed input

If the speed log is not working, enter speed manually as below. In this case the speed data type is shown as "MANUAL" and is speed thru water (STW). Manual speed input is not available on IMO-type radars when the AIS feature is active.

1.16 How to Start/Stop Transmission

The radar is ready to transmit when the message "STBY" appears in the operational display area. Transmission can be started using one of the following procedures:

• Using the control unit: Press the STBY TX key.

• Using the on-screen box: Left-click the button on the InstantAccess bar

When the radar is switched to TX (transmit) status, most settings (such as brilliance, range, pulse width, etc) are restored with the same settings as before standby.

For magnetron radars, it is recommended to place the radar in standby when transmission is not required, to reduce wear on the magnetron. You can also set a “blank sector” where transmission is stopped (see the Installation Manual for details).

How to stop antenna rotation

Antenna rotation can be stopped using one of the following procedures:

• Turn the antenna switch off.

™

• Turn antenna rotation off from the menu (See installation manual).

Screen freeze

The screen is not refreshed if the screen has frozen. An audio alarm is released 30 seconds after a screen freeze. The ALARM ACK key flashes and a contact alert sig- nal is also released. To return the radar to normal operation, turn the radar off, then on again.

Quick start

Provided that the radar was in use and the magnetron (transmitter tube) is still warm, you can switch to transmit mode without the three minute warm-up time. If the radar was turned off by mistake or you wish to restart the radar promptly, wait several seconds before you press the POWER switch.

1.19 How to Adjust 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.

How to adjust the GAIN from the control unit (RCU-014)

Rotate the GAIN knob. Rotate anticlockwise to decrease the gain, or clockwise to increase the gain.

1.20 How to Reduce 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 extends. When sea clutter masks the picture, reduce it with the A/C SEA control, either manually or automatically.

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

Note 2: The echo average function (see section 1.24) is useful for reducing reflections from the sea surface. However, high-speed targets are harder to detect than stationary ones when echo average is active.

1.20.1 How to select the method of clutter adjustment

1.20.2 How to fine-tune sea clutter reduction

Auto A/C SEA allows for fine tuning of the A/C SEA circuit, within ±20 dB. Accordingly, with the bar reading set to 50, 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 the echoes because the STC curve changes with the size of the echoes.

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

How to fine-tune sea clutter reduction from the control unit (RCU-014)

Rotate the AC/SEA knob. Rotate anticlockwise to decrease the AC/SEA, or clockwise to increase the A/C SEA.

How to fine-tune sea clutter reduction from the on-screen box

2. Place the arrow on level indicator inside the A/C SEA box at the top of the display.

3. While observing the A/C SEA level indicator, spin the scrollwheel to adjust the clutter reduction. The setting range is [-50] to [50].

1.20.3 How to manually reduce sea clutter

Sea clutter at screen center

Note: 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.

1.21 How to Reduce Rain Clutter

Use the AUTO RAIN and A/C RAIN to reduced rain clutter. AUTO RAIN reduces rain clutter in the picture and A/C RAIN reduces clutter picked up by the antenna.

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

1.21.2 How to manually reduce the 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.

Note: 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 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.

Interference from radars using the same frequency.

1.22 Interference Rejector

Mutual radar interference can 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.

You can access this feature from the InstantAccess bar

™

, or from the menu. The avail-

able settings are: [OFF], [1], [2] or [3].

Note: When multiple radars using the same frequency are nearby, interference may appear in a similar manner to that shown in the figure to the right. If this kind of interference appears, do one of the following:

• Press the HL OFF key, or click the [HL OFF] button on

the InstantAccess bar™.

• Change the range.

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 types of echo stretch, 1, 2 and 3, and the higher the number the greater the amount of stretch.

Note: The echo stretch magnifies not only small target pips but also returns (clutter) from sea surface, rain and radar interference. For this reason, make sure these types of interference have been sufficiently reduced before activating the echo stretch.

1.24 Echo Averaging

The echo averaging feature 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 a 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. However, true echo averaging is not 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.

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

Note 3: Echo averaging requires heading, position and speed data.

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. The available settings options are shown in the table below.

Setting

[OFF] Echo averaging is not enabled [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 current conditions. For effective monitoring of high-speed craft, you should use [2] together with the Wiper function.

1.28 How to Preset Controls for a 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 [ROUGH SEA], and is designed to be used in heavy rain.

Three user-programmable presets are also provided (labeled as [CUSTOM1], [CUSTOM2] and [CUSTOM3]), so that you can have the radar automatically set to those conditions which are not covered by the provided setup options.

Below are the preset options provided with this radar.

Preset Description

[CUSTOM1], [CUSTOM2] and [CUSTOM3]

[NEAR] Optimum setting for short range detection using a range

[FAR] Optimum setting for long range detection, on a range

[NEAR BUOY]* Optimum setting for detecting buoys within 3 NM range. [FAR BUOY] Optimum setting for detecting buoys on a range scale of

[ROUGH SEA] Optimum setting for rough weather or heavy rain. [SHIP] Optimum setting for detecting other vessels. [HARBOR] Optimum setting for harbor berthing. [BIRD] Optimum setting for detecting birds. [ICE]* Optimum setting for navigating though sea ice. [COAST] Optimum setting for coastal travel.

User-defined custom settings.

scale of 3 NM or less on calm seas.

scale of 6 NM or larger.

6 NM or larger.

*: [SMALL TARGET] replaces [NEAR BUOY] and [ICE] replaces [BIRD] when Ice Mode is enabled at installation.

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

Changing these features from the [CUSTOMIZED 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 ([CUSTOM1], [CUSTOM2] or [CUSTOM3]) when frequent adjustment of the radar image is necessary.

The default settings for the custom presets are listed on the following pages.

About the ICE custom setting (optional specification)

The ICE custom setting sets up the radar to detect areas of ice on the sea surface. With ICE active, the following restrictions or requirements apply:

• For interswitch configurations with a FAR-2xx8 series as the main radar and a FAR2xx7 series as the sub radar, ice echoes may not appear correctly on the FAR-2xx7 series screen. Avoid using a FAR-2xx7 series radar as the interswitch sub-radar with Ice Mode enabled.

• Ice Mode must be enabled from the [RADAR INSTALLATION] menu. See the Installation Manual for details.

• Dual radar mode must be disabled from the [RADAR INSTALLATION] menu. See the Installation Manual for details.

• Ice Mode replaces Bird Mode. While Ice Mode is in use, Bird Mode-related settings and operations are not available.

• Video Contrast settings are fixed to ICE settings when the performance monitor is activated while Ice Mode is enabled.

• While Ice Mode is enabled, the following functions are not available:

• Target Analyzer • Rain Echo Hatching • Video Contrast

• Automatic Clutter Elimination (ACE) • Fast Target Emphasis • Trail Hide

1.30 Orientation Modes

This radar has the following orientation modes available:

Mode Description

Relative Motion (RM) modes

[HEAD UP RM] Not stabilized [STERN UP RM]* The radar image is rotated 180°. Graphics and relative and

true bearings are also rotated 180°.

[STAB HEAD UP RM] Head-up with compass bearing scale (True Bearing) where

the bearing scale rotates with the compass reading.

[COURSE UP RM] Compass-stabilized relative to ship’s orientation at the time of

selecting COURSE UP.

[NORTH UP RM] Compass-stabilized with reference to North.

True Motion (TM ) modes

[NORTH UP TM] Land objects and sea are stationary. Requires compass and

speed data.

*: [STERN UP RM] is only available for A/B/W-types.

1.30.1 How to select an presentation mode

Select the [ORIENTATION MODE] box at the top left corner of the screen, then left-click to cycle through the available orientation modes.

Loss of gyrocompass signal

When the compass signal is lost, "LOST GYRO SIGNAL" appears in yellow-orange in the [ALERT] box, the orientation mode automatically becomes HEAD UP, and TT and AIS objects, map and chart are erased. Stop the alert with the ALARM ACK key or left-click the [ALERT] box. Check the GYRO data.

1.30.2 Description of presentation modes

HEAD UP mode

A display without azimuth stabilization in which the line that connects the center with the top of the display indicates your heading. Targets are shown at their measured distances and their directions relative to your heading. The short dotted line on the bearing scale is the north marker.

1. OPERATIONAL OVERVIEW

The radar picture is stabilized and displayed with the currently selected course at the top of the screen. When you change the heading, the heading line 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 directions relative to the set course, which is at the 0-degree 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.

STAB HEAD UP mode

North marker

Heading line

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 gyrocompass. If the gyrocompass fails, the bearing scale returns to the state of HEAD UP mode.

True motion mode

Your ship and other objects in motion move with their true courses and speed. All fixed targets, like landmasses, appear as fixed echoes in ground stabilized TM. When your ship reaches a point that is 50% of the radius of the display, the position is reset. The ship appears at 75% radius opposite to the extension of the current course. You can manually reset your ship symbol if you highlight the [CU/TM RESET] indication at the top of the screen, then left-click.

• [ANT]: When OFF CENTER is active, the bearing scale intervals change accordingly.

• [CCRP]: When the CCRP moves outside the operational display area, the bearing scale intervals may not be displayed correctly.

STERN UP mode

The STERN UP mode rotates the HEAD UP mode picture, relative and true bearings and display graphics 180°. This mode is useful on dual-radar tugboats when backing up; one radar shows HEAD UP and another shows STERN UP. To enable the STERN UP mode, turn on [STERN UP] on the [OPERATION] menu.

Note: STERN UP mode is only available for A/B/W-types.

1.31 How to Select a Range Scale

The selected range scale and range ring interval are shown at the upper left corner on the screen. When a target of interest comes closer, reduce the range scale so that it appears in 50-90% of the display radius.

1. Place the cursor in the [RANGE] box at the top left corner of the screen.

In the above example, the range scale is set to 0.125 NM and the interval between range rings is set to 0.025 NM.

2. Left-click to lower the range; right-click to raise the range.

You can also select the range with the RANGE key on the control unit. Press "+" to increase the range, or press "-" to reduce the range. Press and hold a key to successively change the range upwards or downwards.

Changing the plotter range (A/B/W-types with Radar Plotter functionality only)

With the radar in standby (STBY) mode, you can change the plotter range by pressing the RANGE key. In this case, “range” means the on-screen displayed distance from the left-hand edge of the screen to the right-hand edge of the screen.

[+]: expands the range scale with the cursor location as the center.

[-]: reduces the range scale with the cursor location as the center.

Press and hold the [+] or [-] key to change the range scale continuously.

1-50

1.32 How to Measure Range

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

Use the fixed range rings to get an estimate of the range to a target. The rings are the concentric solid circles on the display. The number of rings is automatically set by the current range scale. The distance between the rings is the range ring interval, and the current interval appears at the upper-left position on the screen. To measure the range to a target with the range rings, count the number of rings between the center of the display and the target. Check the range ring interval and estimate the distance of the echo from the inner edge of the nearest ring.

1.33 How to Measure Bearing

The Electronic Bearing Lines (EBLs) are used to take bearings of targets.There are two EBLs, EBL1 and EBL2. Each EBL is a straight dashed line extending out 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 EBL2 are longer.

Each EBL has an EBRL (Electronic Bearing Range Line, indicated as a short line, crossing the EBL at right angles). When VRM is not displayed and only EBL is displayed, the EBRL shows the range from the EBL origin.

When VRMs are displayed with EBLs the VRM overlaps the EBRL. The value for EBRL and VRM is the same and is displayed in the VRM box at the bottom-right of the screen.

No echo adjustment (Target analyzer off, EAV off, hatching off) Rain, moving targets and surface reflections are all displayed with no filtering.

Minimal echo adjustment (Target analyzer on, EAV off, hatching off) Echoes are colored, surface reflections are filtered, rain is displayed.

Maximum echo adjustment (Target analyzer on, EAV on, hatching on) Echoes are colored, surface reflections are filtered, rain is displayed in gray colored hatching.

Moderate echo adjustment (Target analyzer on, EAV on, hatching off) Echoes are colored, surface reflections and rain are filtered.

1.38 Target Analyzer (B/W-type only)

The target analyzer function analyzes echoes and assists the operator to determine dangerous targets. This function is particularly useful under heavy rain/snow or where there is surface reflection, which can cause interference and noise.

The target analyzer function can also place hatching over heavy rain areas, reducing the visible interference and allowing a clearer view of potential targets.

Echoes are displayed in five different colors to assist the operator in identifying targets. The colors and their respective echoes change depending on the echo color selected from the [BRILL] menu (see section 1.45) are shown in the table below.

Target Analyzer indication

Note 1: This function works best when the settings for [GAIN], [STC], [RAIN], [NOISE REJECT] and [VIDEO CONTRAST] are properly adjusted (surface reflections are displayed in green and rain is displayed in gray).

Note 2: This function recognizes moving targets as approaching targets. Buoys and other stationary objects are not recognized as approaching targets by this function.

Note 3: The target analyzer function requires a short period of time to analyze echoes and display them on-screen. If your antenna revolves at more than 40 rpm, moving targets may not be displayed correctly. For this reason, caution is advised when using the target analyzer function.

Note 4: The target analyzer function’s performance may be affected by factors such as target size, weather and sea conditions, physical equipment configuration, offset settings and other factors.

Note 5: When the high speed function mode is activated (at installation), this function is automatically deactivated at a range of 2 NM or less. For details of the high speed rotation mode, contact your dealer.

What is “hatching”?

Where echo averaging may hide light rain on the display, the hatching feature, when activated, places a gray “veil” over the areas where rain is detected. This allows the operator to see where the rain is without affecting the quality of the displayed echoes.

Note 1: To create a 360° alarm zone, set Point B at the same location as Point A.

Note 2: Two alarm zones can be set simultaneously. The second alarm zone is only

available when the first alarm zone is active, however.

Note 3: When the target alarm zone is not within the range in use the indication "UP RNG" appears to the right of the target alarm box. In this case select a range that will

display the target alarm zone.

1.39.2 How to mute the target alarm

A target in the target alarm zone produces both visual (flashing) and audible (beep) alarms. To silence the audio alarm select the appropriate target alarm box then leftclick. The target alarm box indication shows "MUTE". This will deactivate the audio alarm but will not stop the flashing of the offending target. You can also stop the alarm by deactivating the target alarm zone (see section 1.39.3).

To reactivate the audio alarm, select the target alarm box then left-click to show "WORK" in the box.

1.39.3 How to deactivate a target alarm

Select the target box to be deactivated, then press and hold the left button on the Control Unit.

Note: When both alarm zones are active, the second ([2:]) alarm zone must be deactivated before the first ([1:]) can be deactivated. If both zones are active when you try to deactivate zone [1:], the system releases two audible beeps and shows the message "DELETE ALR2 FIRST".
