Chapter 5 VARIOUS FUNCTIONS

Head Up (H-UP) mode is displayed so that the ship’s heading line points to the zenith of the PPI. Since
targets are displayed in their direction relative to the ship’s heading line, the operator can view the video in the
same field of view as in operating the ship at sea. This mode is suitable for watching over other ships.
North Up (N-UP) mode is displayed so that the zenith of the PPI points to the due north. Fixed targets do no
flicker and are easily identified on the chart, and the true bearing of a target can easily be read out.
Course Up (C-UP) mode is fixed pointing to the zenith of the PPI points to the due north. In the same way as
in the N-UP mode, fixed targets do not flicker, and are stabilized even if the ship is yawing. The bearing of the
heading line varies by the same shift of own ship’s course. If the course is changed while “Course Up” is
selected, the latest course will be displayed top of the radar screen by selecting “Course Up Reset.”
