You select the position of the fixed location as described in "Offsetting the PPI center" on page 21. 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. A B When true motion is selected, the true motion reset option is available from the menu. This allows for manually resetting the radar image and vessel symbol to its starting position. Ú Note: True motion is only available when the PPI is in either north up or course up orientation mode. To set to true motion in the MFD, select the Position option in the More menu and then select the True motion option. Radar symbology Use this menu option to collectively turn on/off radar symbology which are selected to show in the Radar Settings panel (refer to "Radar settings" on page 25). Target trails A target trail indicates the target movement by leaving an afterglow, gradually reducing the intensity over time. Target trails show where a target used to be, and the function is useful for quickly assessing the movement of targets relative to your own vessel. You can set the length of the trails. The length represents the time it takes for the trails to fade out. You can also turn OFF target trails. ADDENDUM | HDS Series 23
