3. STEERING MODE
Navigating to TLL point
When TLL (Target Latitude and Longitude) data is input from a radar or echo sounder connected in the STBY, AUTO or NAV mode, the TURN menu appears. Then, you may choose how to progress towards that position, from ORBIT (port direction, starboard direction) or FIGURE EIGHT. (You may also continue current steering mode, by choosing OFF.) For this mode, own ship’s position L/L data and waypoint L/L data are required.
ORBIT
The boat makes circles around the TLL point.
SPIRAL
The boat goes to the TLL point spirally. After arriving to the TLL, the boat begins orbiting around there.
FIGURE EIGHT
The boat automatically returns to the TLL position when it goes more than a distance (set on menu) away from the TLL position.
