Note 1: If the target goes out of the picture or the tilt angle is greater than 60 degrees the lamp above the [TARGET LOCK] key flashes to call your attention.
Note 2: Target lock position and data are calculated according to tilt angle.
Note 3: The bearing mark moves to the target lock mark loca- tion when target lock becomes active. Bearing to the target lock mark is shown.
Note 4: Target lock is temporarily disabled when the distance to the tracked fish school is less then 40 m. It is resumed once the distance becomes more than 40 m.
Note 5: The target lock works up to a tilt angle of 60 degrees. In the drawing below, the tilt angle is fixed at 60 degrees between B and C. During this period, however, calculation is continu- ously being performed. When own ship comes to point C, target lock is resumed.
