1.4 Choosing Presentation Mode
Five presentation modes are available by the [MODE] key: head-up, head-up true bearing,
course-up, north-up, and true-motion. (North-up, head-up true bearing, course-up and true
motion require a heading signal. TM mode additionally requires a speed signal.) Each time
the key is pressed, if heading is input to the radar, the display and the display mode
indication at the top left corner of the display change in the sequence of HU, HU TB, CU,
NU and TM. If there is no heading signal input, the display mode is always HU.
