3. TARGET TRACKING (TT) 3.10.2 How to change the vector length (time) The vector time provides an estimation of the target’s vector and can be adjusted as follows: Place the cursor on the vector time indication in the [Vector] box, then press the left button. The vector time cycles through the following settings with each press of the left button. [6min] [10min] [20min] [30min] [45min] [60min] [30sec] [1min] [3min] [5min] [6min]... The vector tip shows an estimated position of the target after the selected vector time elapses. It can be valuable to extend the vector length to evaluate the risk of collision with any target. 3.11 Past Position Display The past position display shows equally time-spaced dots marking the past positions of any targets being tracked. A new dot is added every minute (or at other preset time intervals) until the preset number is reached. If a target changes its speed, the spacing will be uneven. If it changes the course, its plotted course will not be a straight line. Past position orientation, true or relative, is controlled with [TRAIL MODE] in the [TRAIL] context menu. To adjust the trail orientation, see paragraph 1.36.1. 3.11.1 How to display past position points and select the past position plotting interval Place the cursor on the [PAST POSN] time indication in the [PAST POSN] box, then press the left button. The past position points are displayed and their plotting interval changes with each press of the left button, as shown below. [OFF] [30sec] [1min] [2min] [3min] [6min] [OFF]... 3.11.2 How to select the number of past position points to be displayed 1. Open the [MAIN MENU]. 2. Select [TT•AIS], then press the ADJUST knob. 3. Select [TT•AIS SYMBOL], then press the ADJUST knob. 4. Select [TT•AIS PAST POSN POINTS], then press the ADJUST knob. 5. Select [5] or [10] as appropriate, then press the ADJUST knob. 6. Close the menu. 3-12 3. TARGET TRACKING (TT) 3.12 Set and Drift Set, the direction in which a water current flows, can be manually entered in 0.1-degree steps. Drift, also known as “Rate”, or the speed of the current, can also be entered manually in 0.1-knot steps. When course through water and speed through water are available, activate set and drift to get course over ground and speed over ground. Set and drift corrections are beneficial for increasing the accuracy of vectors and target data. Refer to the tide table on board the ship for setting information. These values are applied to all targets. If stationary targets have vectors, set and drift values should be adjusted until they lose vectors. To enter set and drift do the following: 1. Select the [SPD] menu box, then press the right button. The [SHIP SPEED MENU] is displayed. 2. Select [SET DRIFT], then press the ADJUST knob. 3. Select [ON], then press the ADJUST knob. The setting can now be adjusted and [SET] is selected. 4. Rotate the ADJUST knob to select the appropriate setting (Setting range: 000.0° to 359.9°), then press the ADJUST knob. The [DRIFT] setting is now selected. 5. Rotate the ADJUST knob to select the appropriate setting (Setting range: 00.0kn to 19.9kn), then press the ADJUST knob. 6. Close the menu. Note 1: Set and drift are available when using manually input speed, speed through the water. The speed source is shown as "WTC" (Water Tracking Count). Note 2: Set and drift should be checked periodically for correctness. Note 3: When speed data input from the position sensor is valid, set and drift is not adjustable. 3-13 3. TARGET TRACKING (TT) 3.13 Collision Alarm (CPA, TCPA) This radar calculates CPA and TCPA by using own ship and relative target positions. The TT continuously monitors the predicted range at the Closest Point of Approach (CPA) and predicted time to CPA (TCPA) of each TT. When the predicted CPA of any TT becomes smaller than a preset CPA range and its predicted TCPA less than a preset TCPA limit, the audio alarm sounds and TT COLLISION appears (in red) in the Alert Box. In addition, the symbol of the offending TT is red and flashes together with its vector. CAUTION CPA/TCPA Alarm The CPA and TCPA alarm feature should never be relied upon as the sole means for detecting the risk of collision.The navigator is not relieved of the responsibility to keep visual lookout for avoiding collisions, whether or not the radar or other plotting aid is in use. This feature, when used correctly, helps prevent the risk of collision by alerting you to threatening targets. It is important that GAIN, A/C SEA, A/C RAIN and other radar controls are properly adjusted. CPA and TCPA ranges must be set up properly taking into consideration the size, tonnage, speed, turning performance and other characteristics of own ship. The reference point for CPA and TCPA calculation can be selected from antenna position or conning position. For further details, see section 1.47. 3.13.1 How to set the CPA and TCPA ranges CPA and TCPA ranges can be adjusted from the appropriate indication in the [TT] box. CPA setting TCPA setting 1. Place the cursor on the indication you wish to adjust. 2. Press the left button, or rotate the ADJUST knob, to adjust the settings as required. The settings options are outlined in the table below. 3.13.2 Indication CPA Key Left button ADJUST knob TCPA Left button ADJUST knob Settings options 0.5, 1, 1.5, 2, 3, 4, 5, 6 (nm) 0.1-20 (nm), 0-10 nm in 0.1 nm increments, 10 nm increments thereafter 1, 2, 3, 4, 5, 6, 12, 15 (minutes) 1-60 minutes, 1-minute increments How to acknowledge the TT collision alarm Press the key on the control unit, or select the [ALERT] box with the Touchpad then press the left button to acknowledge the alarm and silence the buzzer. The alert "TT COLLISION" and the flashing of the plotting symbol and vector remain in the Alert Box until the dangerous situation is gone or you intentionally terminate tracking of the target. Note that when the TT COLLISION alarm is generated the AIS display is automatically turned on. 3-14 3. TARGET TRACKING (TT) 3.14 Acquisition Zone The acquisition zone functions both to alert you targets in a specific area and acts as an automatic acquisition area when automatic target acquisition is active. Any targets entering the zone will be automatically acquired. When a target enters an acquisition zone, the buzzer sounds and the indication "TT NEW TARGET" (or "AIS NEW TARGET") appears (in yellow-orange) in the Alert Box. The symbol of the offending target is red and flashing. Further, the AIS display is automatically turned on if it is off. There are two types of acquisition zones available, arc and polygon, however, AZ1 can only be set as an arc. Note: The [AZ1] and [AZ2] boxes are not displayed when the setting for [AZ/ALR SELECT] in the [TT•AIS] menu is set to [TARGET ALARM ZONE]. 3.14.1 How to activate the first acquisition zone (AZ1) The No. 1 acquisition zone is available between 3 and 6 nm The TT/AIS acquisition zone’s lines are white and dashed so as to distinguish them from the radar target alarm. The procedure below shows how to set AZ1, using the example at the bottom of the page. 1. Place the cursor on the [AZ] indication at the bottom-right of the screen. 2. Press the left button to cycle through the settings and select [SET]. 3. Place the cursor on the acquisition zone starting point (“A” in the figure below), then press the left button. 4. Place the cursor on the acquisition zone end point (“B” in the figure below), then press the left button. 5. Press the right button to complete the acquisition zone set up. 0.5-1 nm Target in acquision zone is red and flashing. 3-15 3. TARGET TRACKING (TT) 3.14.2 How to set a polygon acquisition zone (AZ2) The No. 2 acquisition zone can be set anywhere when the No. 1 zone is already in use. Polygon zones must have at least three points. To set a polygon shaped acquisition zone: 1. Place the cursor on the [AZ] indication at the bottom-right of the screen. 2. Press the left button to cycle through the settings and select [SET]. 3. Place the cursor on the acquisition zone starting point, then press the left button. 4. Place the cursor on the second point, then press the left button. 5. Repeat step 4 as required to set the remaining points of the polygon zone. 6. Press the right button to complete the acquisition zone set up. Notes on acquisition zones • If you wish to create an acquisition zone having a 360-degree coverage around own ship, set point B in almost the same direction (approx. ±3°) as point A, then press the left button. • The default acquisition zone is fan shaped. It can also be a polygon having 3-10 points. • If both acquisition zones are displayed, a maximum of four polygon points are shown. • TT and AIS are automatically set to TT=AUTO and AIS=DISP, respectively, when an AZ is activated in the following conditions: TT AIS 3.14.3 : TT=OFF or TT=MANUAL 50 : AIS FUNC=OFF or AIS DISP=OFF How to sleep/deactivate an acquisition zone 1. Select the appropriate [AZ] box. 2. Sleep, or deactivate, the acquisition zone, as explained below: Sleeping the acquisition zone Press the left button several times until the indication shows "SLEEP". Deactivating the acquisition zone Press and hold the left button until the AZ box becomes blank. 3.14.4 How to acknowledge the acquisition zone alert Press the key on the control unit, or select the [ALERT] box with the Touchpad then press the left button to acknowledge the alarm and silence the buzzer. 3-16 3. TARGET TRACKING (TT) 3.14.5 How to change the acquisition zone reference The acquisition zone can be referenced to heading or North using the following procedure: 1. Open the [MAIN MENU]. 2. Select [TT•AIS], then press the ADJUST knob. 3. Select [ACQUISITION ZONE], then press the ADJUST knob. 4. Select [AZ STAB], then press the ADJUST knob. 5. Select [STAB HDG] to reference heading, or [STAB NORTH] to reference North. 6. Close the menu. 3.14.6 How to set acquisition zone shape and stabilization The shape of the No. 2 acquisition zone can be a sector or a polygon having up to 10 points. (The shape of the No.1 acquisition zone is always a sector.) 1. Open the [MAIN MENU]. 2. Select [TT•AIS], then press the ADJUST knob. 3. Select [ACQUISITION ZONE], then press the ADJUST knob. 4. Select [AZ POLYGON], then press the ADJUST knob. 5. Select the appropriate setting, then press the ADJUST knob.

Stabilized against ground. Polygon having 3-10 points. Stabilized against heading. Polygon having 3-10 points. Stabilized against North. 6. Close the menu. 3-17 3. TARGET TRACKING (TT) 3.15 TT System Messages There are four main reasons the TT may trigger the audio and visual alerts: • Collision alarm • Acquisition zone alert • Lost target alert • Target capacity To acknowledge the alert, press the key on the control unit, or select the [ALERT] box with the Touchpad then press the left button to acknowledge the alert and silence the buzzer. Alert message TT COLLISION Priority Alarm TT NEW TARGET Warning TT LOST Warning REF TARGET LOST Warning TT TARGET FULL (AUTO) or (MAN) TT TARGET 95% (AUTO) or (MAN) Warning 3-18 Caution Meaning A tracked target is on collision course with your vessel. Tracked target has entered an acquisition zone. The tracked target's symbol is red and flashing. When the system detects a loss of a tracked target, the lost tracked target symbol appears in red and flashes. At the same time, an audio alert is produced for one second. The lost target mark disappears from the screen after the lost target alert is acknowledged. When the system detects a loss of a reference target, the target symbol turns red and flashes. At the same time, an audio alert is produced for one second. The reference target mark disappears from the screen after the reference target alarm is acknowledged. Appears when capacity for automatically (manually) acquired targets is full. Appears when capacity for automatically (manually) tracked targets is 95% full. Action required Take evasive action or terminate tracking of TT. Confirm the tracked target, then press the key. Confirm the lost target, re-acquire if necessary. To continue using a referenced target for speed input, select another tracked target. To continue acquiring targets, cancel tracking for unnecessary targets. 3. TARGET TRACKING (TT) 3.16 TT Simulation Mode You can simulate the risk of a collision by using the TT simulation mode. The test can be terminated at any time by pressing the key. 1. Open the [MAIN MENU]. 2. Select [INTIAL SETTING], then press the ADJUST knob. 3. Select [TEST], then press the ADJUST knob. 4. Select [TT TEST], then press the ADJUST knob. The normal operation is suspended then three simulated targets appear on the display. The indication "S" appears at the bottom of the effective display area during the simulation mode. The simulation may be terminated any time by going to the STBY mode. Three simulated targets move as the following table. The simulated target is automatically generated with the relative movement in the following table based on own ship's movement at the start of simulation mode. Note: If own ship moves after the start of simulation mode, the movement of the simulated target is not matched with the values in the following table. Target 01 Target 02 Target 03 Range (R) 9.5 NM 1.1 NM 9.3 NM Bearing (R) 270.0° 333.0° 45.0° Speed (R) 20.0 kn 10.2 kn 19.9 kn Course (R) CPA TCPA 90.0° 0.0 NM 28.5 min 90.2° 1.0 NM 2.9 min 225.1° 0.0 NM 28.0 min 03 01 02 Place the cursor on a target, then press the key to display the target data. Acquire the simulated targets after the TT simulation mode is performed. The tracking state changes from unstable to stable and the vector appears. You can simulate the movement of each function with changing true/relative vector, stabilization through the water/over the ground, range or length of vector. Repeat the check for all targets. 3-19 3. TARGET TRACKING (TT) 3.17 Criteria for Tracking Target Selection The FURUNO TT video processor detects targets in midst of noise and discriminates radar echoes on the basis of their size. Target whose echo measurements are greater than those of the largest ship in range or tangential extent are usually land and are displayed only as normal radar video. All smaller ship-sized echoes that are less than this dimension, are further analyzed and regarded as ships and displayed as small circles superimposed over the video echo. When a target is first displayed, it is shown as having zero true speed but develops a course vector as more information is collected. In accordance with the International Marine Organization Automatic Radar Plotting Aid (IMO TT) requirements, an indication of the motion trend should be available within 20 scans of antenna and full vector accuracy within 60 scans. The FURUNO TTs comply with these requirements. Acquisition and tracking criteria A target which is hit by five consecutive radar pulses, is detected as a radar echo. Manual acquisition is done by designating a detected echo with the trackball.Automatic acquisition is done in the acquisition areas when a target is detected 5-7 times continuously depending upon the congestion. Tracking is achieved the target is clearly distinguishable on the display for 5 out of 10 consecutive scans, whether acquired automatically or manually. Required tracking facilities are available within 0.1-32 nm on range scales including 3, 6, 12 nm, full plotting information is available within one scan when the range scale has been changed. Targets not detected in five consecutive scans become “lost targets”. Quantization The entire picture is converted to a digital from called “Quantized Video”. A sweep range is divided into small segments and each range element is”1” if there is radar echo return above a threshold level, or “0” if there is no return. The digital radar signal is then analyzed by a ship-sized echo discriminator. As the antenna scans, if there are five consecutive radar pulses with 1’s indicating an echo presence at the exact same range, a target “start” is initiated. Since receiver noise is random, it is not three-bang correlated, and it is filtered out and not classified as an echo. The same is true of radar interference. Electronic circuits track both the closet and most distant edges of the echo. At the end of the scanning of the echo, the discriminator indicates the measured maximum range extent and total angular extent subtended by the echo. If the echo is larger than a ship-sized echo in range extent and/or angular width, adjusted as a function of range, it is declared to be a coastline and the closet edge is put into memory as a map of the area. This land outline is used to inhibit further acquisition and tracking of ship-sized echoes beyond the closest coast outline. Five consecutive scans of coastal outline are retained in memory to allow for signal variation. All smaller echoes are declared to be ship sized and the middle of the leading edge is used to provide precise range and bearing coordinates of each echo on every scan. This range/bearing data is matched to previous data and analyzed from scan-to-scan for consistency. When it is determined to be as consistent as a real target, automatic acquisition occurs and tracking is initiated. Continued tracking and subsequent calculation develop the relative course and speed of the target. 3-20 3. TARGET TRACKING (TT) The true course and speed of own ship are computed from own ship's gyro and speed inputs, and the resulting course and speed of each tracked target is easily computed by vector summing of the relative motion with own ship’s course and speed. The resulting true or relative vector is displayed for each of the tracked targets. This process is updated continually for each target on every scan of the radar. Qualitative description of tracking error The FURUNO TT's accuracy complies with or exceed IMO standards. Own ship maneuvers For slow turns there is no effect. For very high turning rates (greater than 150°/minute, depending on gyro), there is some influence on all tracked targets that lasts for a minute or two then all tracked targets revert to full accuracy. Other ship maneuvers Target ship courses, lag 15 to 30 seconds at high relative speed, or 3 to 6 seconds at low (near 0) relative speed. It is less accurate during a turn due to lag, but accuracy recovers quickly. 3.18 Factors Affecting TT Functions Low gain Insufficient or low radar receiver gain will result in some targets not being acquired at long distance. TT display will be missing on one or more targets that could only be visible if the radar sensitivity control (GAIN control) were increased. The setting of the correct radar receiver gain is not critical but the target should be on the radar PPI and be clearly visible and well defined. Manual acquisition is done if a target is positively displayed more than once. Automatic acquisition is done when the target is detected 5-7 times continuously. Tracking is achieved when the target is detected five times (not necessarily continuously) out of 10 scans. If not detected six times out of 10 scans, the target will become a “lost target”. The TT will acquire a radar echo that is present once in every six antenna scans and continue tracking if 1 in 10. Sea returns If the radar anti-clutter control is adjusted properly, there is no serious effect because distant wave clutter, not eliminated by this control, is filtered out by more than one bang correlation and scan-to-scan matching of data. Rain and snow Clutter can be acquired and tracked as targets. Adjust the A/C RAIN control. If it is heavy rain, switch to S-band if provided, or switch on the interference rejector on the radar. If heavy clutter still exists, switch to manual acquisition. Accuracy can be affected. Low clouds Usually no affect. If necessary, adjust the A/C RAIN. 3-21 3. TARGET TRACKING (TT) Non-synchronous emissions No effect. Second trace echoes When the radar beam is super refracted, strong echoes may be received at such long ranges that they appear on a different timebase sweep than the transmitted pulse. This gives an incorrect range indication. Second and third trace echoes can be tracked if they are consistent enough to meet acquisition and tracking criteria but target course and speed data will be in error. Blind and shadow sectors Radar shadow or blind areas caused by obstructions aboard ship, for example, funnels and masts, in the path of the radar beam can result in reduction of radar beam intensity in that particular direction. This may eliminate the detection of some targets. The TT system will lose track of targets shortly after they are lost on the radar picture and if they remain in a blind zone. These targets will however be acquired and tracked when they pass out of the blind zone and again present normal radar echo. The angular width and bearing of any shadow sector should be determined for their influence on the radar. In certain cases false echoes in the shadow sector cause the TT system to acquire, track, and vector them. Shadow sectors should be avoided. Indirect echoes A target at close range is usually picked up directly, but it can also be received as reflection from a large, flat surface. This will result in the radar presenting two or more echoes on the display, each at a different range. The TT can acquire and track the false echo if it is detected by five consecutive scans. Reduction in radar gain can eliminate the multiple echoing but care should be taken as range detection also will be reduced. Radar interference If interference is extreme due to another radar operating at close range, spiral “dotting” and/or false targets may appear momentarily. The interference rejector can clear the display. To receive radar beacon or SART signals, turn on [SART] in the [ECHO] menu. 3-22 4. AIS OPERATION An AIS transponder can be connected to this radar to overlay AIS targets on the radar display. The radar can store up to 1,000 AIS targets in its storage buffer. When this buffer becomes full of AIS targets, the Alert 190 "TARGET CAPACITY (AIS CAPACITY FULL)" is generated to alert you to full storage buffer. The storage buffer contains automatic dead reckoning for all AIS targets, which is based on reported Speed Over the Ground (SOG), Course Over the Ground (COG), Rate Of Turn (ROT) and heading. The storage buffer also contains calculation of range, bearing, CPA, TCPA, etc. The CPA and TCPA limits set for dangerous targets are common for TT and AIS targets. This radar can activate 40 AIS targets. The Alert 190 "TARGET CAPACITY (AIS CAPACITY FULL)" is generated when 40 AIS targets are activated. This radar can display a maximum of 300 AIS targets. The Alert 190 "TARGET CAPACITY (AIS CAPACITY FULL)" is generated when 300 AIS targets, which includes both activated and sleeping targets, are displayed. The frequency for update of AIS transponder-sent data depends on speed and course of tracked AIS target. The table below shows the IMO standardized reporting rates for the AIS transponder. Based on the table below, the radar defines which AIS targets are in tracking or lost. When you acknowledge a lost target alert, the corresponding AIS symbol will be removed from the display. Type of Ship Class A: Navigation status is “anchor” or “not under command” or “moored” or “aground”, and SOG 3kn Class A: Navigation status is “anchor” or “not under command” or “moored” or “aground”, and SOG > 3kn Class A: 0kn SOG < 14kn Class A: 14kn SOG 23kn Class A: SOG > 23kn Class B: “CS” SOG < 2kn Class B: “CS” SOG 2kn Class B: “SO” 0 kn SOG < 2kn Class B: “SO” 2 kn SOG < 14kn Class B: “SO” 14 kn SOG 23kn Class B: “SO” SOG > 23kn Class A and Class B: no SOG available AIS SAR aircraft AIS aid to navigation AIS base station AIS search and rescue transponder IMO nominal reporting interval 3 min Lost target indication (reporting interval >) 10 min 10 s 50 s 10 s 6s 2s 3 min 30 s 3 min 30 s 15 s 5s N/A 10 s 3 min 10 s N/A 50 s 30 s 10 s 10 min 150 s 10 min 150 s 75 s 25 s 10 min 50 s 10 min 50 s 10 min An AIS transponder “sees” all ships fitted with an AIS transponder belonging to either a Class A or Class B AIS. Additionally, the AIS transponder receives messages from ships and non-ships (AIS SAR aircraft, AIS aid to navigation, AIS base station, and AIS search and rescue transmitter). 4-1 4. AIS OPERATION There can be several hundreds or several thousands of AIS targets, and of those only a few will be significant for your ship. To remove unnecessary AIS targets from the radar display, the feature “active and sleeping AIS targets” is available. Initially any new AIS target received by an AIS transponder is not active (=“sleeping”). Such sleeping targets are shown with a small triangle. The operator can pick any AIS target and change it from sleeping to active. Active AIS targets are shown with a large triangle with speed vector, headline, ROT indicator, etc. Further, the operator can pick active AIS targets and change their status to sleeping. An indication of AIS target activated capacity limit is given well before it is reached. When 95% of 40 targets are activated, the Alert 190 "TARGET CAPACITY (AIS ACITVATE 95%)" appears. When 40 targets are activated, the Alert 190 "TARGET CAPACITY (AIS ACTIVATE FULL)" appears. An indication of AIS target display capacity limit is given well before it is reached. When 95% of 300 targets are displayed, the Alert 190 "TARGET CAPACITY (AIS ACTIVATE 95%)" appears. When 300 targets are displayed, the Alert 190 "TARGET CAPACITY (AIS DISPLAY FULL)" appears. An indication of AIS target processing capacity limit is given well before it is reached. The Alert 190 "TARGET CAPACITY (AIS CAPACITY FULL)" appears when 1,000 targets are in the storage buffer. This radar generates AIS-related alerts. These are Alert 191 "CPA/TCPA (AIS COLLISION" and Alert 193 "LOST TARGET (AIS LOST)". Only active AIS targets generate alerts. The operator can activate or sleep AIS target alerts as desired. The feature “active and sleeping AIS targets” is very effective for focusing on only those AIS targets that need supervision. This radar further eases the task of the operator by automatically changing non-active targets to active targets, if their CPA and TCPA are within a preset limit. 4.1 Controls for AIS Displays AIS target data Cancel target • TGT ACQ: Displays the selected target’s data. • TGT CANCEL: Sleeps the cursor-selected target. These functions, along with other AIS functions, can also be accessed from the [CURSOR] menu (See section 1.7). Select the AIS box, then press the left button to cycle through AIS display modes. DISP OFF: Hides AIS targets DISP FILT: Displays a filtered selection of AIS targets DISP ALL: Displays all AIS targets FUNC OFF: Deactivates the AIS function 4-2 4. AIS OPERATION 4.2 AIS Symbols and Their Meanings When the AIS is active, AIS targets are marked with the appropriate AIS symbol, as shown in the table below. SYMBOL STATUS REMARKS Activated target All AIS symbols shown with thick line. Color is selectable from menu. ROT higher than preset ROT Displayed for turning ship. Dangerous target Displayed when CPA/TCPA is within CPA/TCPA limit. Red in color. Flashing until acknowledged. Lost target “X” overlaid on a lost target. Red in color. Erased after acknowledged. Sleeping target Indicates the presence of a target equipped with AIS. Color is selectable from menu. Target with neither a reported heading nor a COG A target with neither a reported heading nor COG is oriented toward the top of the operational display area. The symbol is shown with a solid line. Target selected Broken square is overlaid on target selected to display its data. for data display A, B or C shown to indicate data box location at right side of the screen. Scaled symbol Symbol shape is based on antenna location, ship length and ship width. Size changes depending on range from own ship. Note 1: The equipment continues to process AIS targets when the AIS feature is deactivated. When the AIS is activated again, symbols are immediately displayed. Note 2: AIS symbols are momentarily erased and the screen is redrawn after the heading is changed in the HEAD UP mode. Note 3: When no AIS data is received, the message "RECEIVE" appears in the Alert Box. Check the AIS transponder. Note 4: Physical and virtual AIS AtoN symbols that may appear are listed on the following page. 4-3 4.

Note 6: The CPA and TCPA of SAR aircraft data are not available and are shown as ***. 4-4 4. AIS OPERATION 4.3 How to Use the AIS Display Filter If there are too many AIS targets on the screen you may wish to remove unnecessary ones. You can remove sleeping targets A/B by distance from own ship, speed and class. For example, you might want to remove slow moving targets, as they normally do not require close monitoring. 1. Open the [MAIN MENU]. 2. Select [TT•AIS], then press the left button. 3. Select [AIS DISP FILTER], then press the left button. 4. Referring to the table below, select the appropriate filtering type, then press the left button. Filter type [MAX RANGE] [MIN SHIP SPEED] [EXCEPT CLASS B] [EXCEPT BASE STATION] [EXCEPT PHYSICAL ATON] [EXCEPT VIRTUAL ATON] Definition Any sleeping AIS targets class A/B beyond the range set here will not be shown. Any sleeping AIS targets class A/B slower than this setting will not be shown. Select [ON] to remove sleeping AIS targets class B. Select [ON] to remove the BASE STATION symbol. Select [ON] to remove the AIS PHYSICAL ATON symbol. Select [ON] to remove the AIS VIRTUAL ATON symbol. 5. Rotate the ADJUST knob to set the selected filter’s options, then press the ADJUST knob. 6. Close the menu. 7. Place the cursor on the [AIS] box, then press the left button several times to display "DISP FILT" in the [AIS] box.

For this reason, a longitude error occurs on the radar display. For example, when own ship is at 60°N and 135°E, even if the cursor indication is 62°N and 139°E, the real cursor position is deviated to the left (west) side. The table below shows the longitude error, represented from 0° to 90° at 96 nm from the radar center (own ship).
