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) modeWhen 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 command set on the autopilot is represented by a small circle on the ROT scale. In addition, " AUTOPILOT" is indicated at the top of the screen. In "autopilot" mode, the autopilot controls the ROT so that actual heading becomes same as commanded one.3) Neither FU nor AP modeWhen the autopilot is in neither FU nor AP mode, the autopilot graph shows ROT command as default.4) No autopilot or on standbyThere is no NMEA signal and also no indication.1.34 Customized MenusThe customized menu settings of four users are programmed individually.

TARGET TRACKING (TT)2-102.10 Vector ModesTarget vectors can be displayed relative to own ship's heading (Relative) or north (True).2.10.1 Description of vectorsSea 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 vectorOwn 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 vectorOther ships move relative to your ship. This mode is useful for finding ships on a collision course with your ship. A ship whose vector passes through your ship's position is on a collision course.2.10.2 Vector mode and lengthVectors may be displayed in true or relative mode.
