few seconds, then beeps again and displays
a navigation warning.

The MOB feature saves the boat’s position and
then navigates back to this point. To do this:

as the waypoint ‘MOB’.

The display changes to the Underway
screen, with a scale of 0.1 miles, with the
MOB waypoint situated in the centre of the
screen. It goes to plotter mode, with a white
screen with crosshatching, rather than
displaying a chart (see section 9-4).

press the Yes key then this might result in
a sudden and dangerous turn.
