Ú Note: Head-up is only available in relative motion mode, and it is the only orientation mode available if the radar is not connected to a heading source. North up In north up mode, the 0° indication on the PPI represents north. The heading line on the PPI is oriented according to own ship heading obtained from the compass. When the ship turns the heading line changes its direction according to the ship's heading, while the radar image remains stabilized. The north up orientation is not available if no heading source is connected to the radar. If heading data is lost, the system will automatically switch to head-up orientation. Course up In course up mode, the top of the bearing scale indicates the ship's true course measured from north at the time course up was activated. When the ship turns the bearing scale remains fixed, while the heading line rotates with the ship's yawing and course change. The course up orientation is reset by re-selecting the course up mode. Offsetting the PPI center You can set the antenna position origin to a different location on the radar PPI. The options described in the next sections are available. PPI center: Center PPI center: Look Ahead PPI Center: Offset Center The Center option resets the antenna position to the center of the PPI. Look ahead The Look ahead option is used to maximize the view ahead of the vessel. When selected the PPI center is placed at 70% of the radius of the PPI, 180° opposite the top of the display. Ú Note: The look ahead option is only available for heading up radar orientation. Offset This option allows you to use the cursor for selecting the PPI center. Move the cursor to the preferred offset position, and confirm your selection. Radar motion mode Radar motion is indicated on the upper left corner of the radar panel as either TM (True motion) or RM (Relative motion). Relative motion In relative motion your vessel remains in a fixed location on the Radar PPI, and all other objects move relative to your position. You select the position of the fixed location as described in "Offsetting the PPI center" on page 12. True motion In true motion your vessel and all moving targets move across the Radar PPI as you travel. All stationary objects remain in a fixed position. When the vessel's symbol reaches 75% of the PPI radius (A), the radar image is redrawn with the vessel symbol re-positioned (B) 180° opposite the current heading bearing. 12 ADDENDUM | Zeus Series
