Auto Mode
In AUTO mode, the autopilot will steer the vessel on your desired Heading. To enter AUTO
mode, press and hold the AUTO button for about 1 second, until the large letter `A´ appears
in the upper left portion of the display (see Figure 43 ).

The vessel’s current actual heading is shown in large letters in the middle of the LCD screen, with the
source and type. Your Desired Heading – also known as the “Commanded Heading” – is shown in
smaller digits at the top-centre of the screen.
When you first enter AUTO mode, the autopilot will use the heading that the boat was on at the
moment the mode was entered as the initial Commanded Heading. To change the Commanded
Heading, use the COURSE CHANGE knob:

A clockwise turn will result in an increase of the Heading.

A counter-clockwise turn will decrease the Heading.

One ‘click’ will change the Heading by 1 degree.

A quick spin of the knob changes the Heading by 10 degrees.
The autopilot will then bring the boat around to the new Commanded Heading at no more than the
rate of turn specified for Turn Rate in the Auto menu. The actual Heading shown in the display will
gradually change to match the Commanded Heading.
Pick up the current heading as the course to steer
When you make a course change, sometimes you may want to stop the turn before the heading
reaches the set heading. Press AUTO button again when you already in AUTO mode will set the
course to the heading at the moment of button press.
