Autopilot graph ROT ±300 º/min RUDDER ±180 º RUDDER graph ROT graph ROT graph The ROT graph displays ship’s rate of turn (degrees/min), using the ROT signal fed from an ROT sensor. The ROT graph is not shown if the ROT signal is lost or inter- rupted. To set the ROT graph scale: 1. Open [MAIN MENU] then click [NAV DATA]. 2. Click [ROT SCALE]. 3. Click the desired scale among 30 degees, 90 degrees and 300 degrees. Rudder graph The rudder graph shows the rudder angle. The rudder graph is not shown if the rudder signal is lost or interrupted.

1. OPERATION Autopilot graph 1) Follow-up (FU) mode When the autopilot is in the follow-up mode, the follow-up rudder command is in- dicated on the RUDDER scale. In addition, "FOLLOW UP" is indicated at the top of the screen. In follow-up mode, the autopilot controls the rudder so that actual rudder angle becomes same as commanded one. 2) Autopilot (AP) mode When the autopilot is in the "autopilot" mode and a ROT signal is available from the autopilot, the autopilot graph shows ROT command. The actual ROT com- mand set on the autopilot is represented by a small circle on the ROT scale. In ad- dition, " AUTOPILOT" is indicated at the top of the screen. In "autopilot" mode, the autopilot controls the ROT so that actual heading becomes same as com- manded one. 3) Neither FU nor AP mode When the autopilot is in neither FU nor AP mode, the autopilot graph shows ROT command as default. 4) No autopilot or on standby The autopilot graph is not shown if the signal is lost/interrupted or if there is no au- topilot connected (includes standby mode). 1.34 Customized Menus Up to four customized menu settings can be saved for up to four different user profiles.

Wrong use can damage the card and destroy its contents. • Make sure the cover of the card drive is closed at all times. • Remove a card with only your fingers. Do not use metal tools (like tweezers) to re- move the card. • Do not remove a card during the reading of the card or writing to the card. • If there is water at the bottom of the card cover, DO NOT open the cover. Remove the water with a dry cloth completely and then open the cover. • The SD cards with the SD or SDHC logo can be used (max. 32 GB). Some SD cards may not work correctly depending on the card type or maker. The memory cards in the table below have been tested and confirmed: Type Capacity Maker Class SDSDB-8192-J95A 8 GB SanDisk 4 SDSDX-008G-J95 8 GB SanDisk 10 SD-E008G4 8 GB TOSHIBA 4 RP-SDW08GJ1K 8 GB Panasonic 10 SDSDX-016G-J35 16 GB SanDisk 10 RP-SDWA16GJK 16 GB Panasonic 10 How to format an SD card You need to format an SD card for use with your PC. If the card be- comes corrupted, format the card with a formatting program that is compatible with the specifications of the SD card. The SD Memory Card Formatting Software made by Panasonic is an example. 1-57

1. OPERATION How to set an SD card The processor unit has two slots for SD cards. The [SD-1] is upper slot and [SD-2] is lower. 1. Pull the tab on the card drive on the processor unit to open the card drive. 2. Put the SD card in the either card drive, [SD-1] or [SD-2], with the label upward. If the card does not set easily, do not use force. 3. Push the card until the card is in position. How to remove an SD card To remove an SD card, select [SD-1] or [SD-2] from the [REMOVE EXTERNAL MEDIA] menu. There are two methods to open [REMOVE EXTERNAL MEDIA] as follows. • [MAIN MENU]–[FILES]–[REMOVE EXTERNAL MEDIA] • [MAIN MENU]–[CAPTURE]–[REMOVE EXTERNAL MEDIA] 1. On [FILES] or [CAPTURE] menu, select [REMOVE EXTERNAL MEDIA]. 2. Select the SD card to remove, [SD-1] or [SD-2]. Note: Select the same card as the card selected on the [DRIVE SELECT] menu. 3. Pull the tab on the card drive cover to open the card drive. 4. Push the card to release the card from the card drive. 5. Remove the card with your fingers then close the cover. Note: Always remove an SD card by this method to prevent non-recognition of the card the next time when it is inserted. If a card is not recognized, insert the card again and do the above operation. 1.35.2 How to save and replay the data All SD card operations begin from the [FILES] menu. [FILES] The [FILES] menu is available in stand-by mode. 1 BACK 2 DRIVE SELECT The data witch is saved in the FR-1908V-BB/FR- SD-1 /SD-2 3 [DRIVE INFO] 1918V-BB do not have the compatibility with other 4 [SAVE DATA] 5 [REPLAY (READ) DATA] models.

[CPA], [TCPA]: CPA (Closest Point of Approach) is the closest range a target will approach to own ship. TCPA is the time to CPA. Both CPA and TCPA are automatically calculated. A negative TCPA value means that you have already passed the CPA and the target is going away from own ship. How to display TT data Click the target on [TT LIST] to show the [TT INFO] window.

2. TARGET TRACKING (TT) 2.10 Vector Modes Target vectors can be displayed relative to own ship's heading (Relative) or north (True). 2.10.1 Description of vectors Sea stabilization is a mode where own ship and all targets are referenced to the sea using a compass heading and single-axis log water speed inputs. Ground stabilization is a mode where own ship and all targets are referenced to the ground using the ground track or set and drift inputs. If the accuracy seems unsatisfactory, enter set and drift corrections. True vector Own ship and other ships move on the display at their true speeds and courses. This mode is useful for distinguishing moving targets from stationary ones. Relative vector Other ships move relative to your ship. This mode is useful for finding ships on a col- lision course with your ship. A ship whose vector passes through your ship's position is on a collision course. A A Buoy Buoy Target on Own ship collision course Own ship B B True vectors in head-up mode Relative vectors in head-up mode 2.10.2 Vector mode and length Vectors may be displayed in true or relative mode. Vector time (or the length of vec- tors) can be set from 30 sec, 1 to 6 minutes. 1. Open [MAIN MENU], click [TT.AIS]. 2. Click [VECTOR].

2. TARGET TRACKING (TT) 2.11 Past Position Display Equally time-spaced dots shows the past position display 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] menu. See section 1.25 for the procedure. (a) Ship turning (b) Ship running (c) Ship reduced (d) Ship increased straight speed speed 2.11.1 How to select the dot number and interval of the past position You may select the number of past points to display per plotting interval as follows. 1. Open [MAIN MENU], click [TT.AIS]. 2. Click [PAST POSN]. [PAST POSN] 1 BACK 2 INTERVAL OFF/0.5min/1min/2min/ 3min/6min 3 POINTS 5/10 3. Click [INTERVAL]. 4.

3. AIS OPERATION The AIS (Automatic Identification System) transponder connected to this radar ex- changes all data and information required by the SOLAS 1994 with other AIS-fitted ships. AIS information is graphically indicated together with the radar and TT informa- tion. When AIS is active, manual or reference speed selection is not available. AIS Function On/Off You may disable or enable the AIS function from the AIS icon. Long press the AIS icon with the left button to switch function between on and off.

Note 2: AIS symbols are momentarily erased after the screen is redrawn when the ori- entation mode is changed from the head-up mode. Note 3: When no AIS data is received, the message "AIS RECEIVE ERROR" appears. Check the AIS transponder. Note 4: An AIS target is declared as lost target if it is not detected in five consecutive reporting periods. 3.2 AIS Display Filter If there are too many AIS targets on the screen you may wish to remove unnecessary ones. You may remove targets by distance from own ship, speed, class and length. For example, you might want to remove slow moving targets, as they normally do not require close monitoring. 1.
