Figure 78 – Typical AUTO Mode Screen
• The boat’s current actual Heading is shown in large letters in the middle of the LCD
screen, with the source & type.
• Your desired Heading – aka “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

• 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.
Notes on AUTO Mode
• If you need to, you can quickly “dodge” around obstacles, and automatically return to
your original Commanded Heading when the boat is clear of the obstacle, without
having to turn the

• You can limit the maximum amount of rudder travel in AUTO mode by turning on the
Auto/Nav rudder limits. Turning them on, and adjusting them to suit, is done in the
Power Steer menu (see page 122).
• The autopilot has an automatic Off-Course Alarm that will be activated should the
boat fall off the Commanded Heading by more than 20°. There is a 32 second delay
on this alarm.
 On a P2VS without an RFU, you should always manually steer a steady,
straight Heading, in STANDBY mode, for at least 10 seconds – or longer, if
necessary, until you don’t have to continue to move the wheel/tiller to
maintain a straight Track – before switching into POWER STEER, AUTO or
NAV modes. The rudder must be at the dead-ahead position when you
switch modes.
