(or the trim button). When you tack, the reference value of the last leg will automatically be displayed.

If the optional analogue steer pilot instrument connected, select sub-function pilot (MEM), as steer reference (See 8.3.2).

The deviation from selected course will be displayed on the analogue steer pilot instrument.

If you do not have the optional trim button or analogue steer pilot connected, we suggest you move the sub-function (TAC) to the NAVIGATE page. Now you can display both the heading and the tactical reference (TAC) at the same time.

Remember to turn off the off course alarm. To turn off the off course alarm, set C32 to (00 ), (See 12.3.3, C32).

10 Man over board (MOB) function

This function will guide you back to the position where the man over board (MOB) button was pressed.

This function requires either a navigator (a NX2 GPS or NMEA navigator can be used) or a speed and compass transducer as well as a man over board (MOB) button. (See Server Manual).

If only a compass and a speed transducer is connected, dead reckoning (MOB) will be displayed on both the Multi Control and the SPEED Log instruments. Dead reckoning (MOB) is also a very useful information, since a person in the water will drift almost as fast as the boat.

If a navigator, a compass and a log transducer is connected, dead reckoning (MOB) will be performed and displayed in the SPEED Log instrument. At the same time the Multi Control instrument will display (MOB) relative position stored in memory when the (MOB) button was activated. A position in latitude and longitude is more important for the sea rescue service.

The (MOB) position is automatically stored in waypoint number 99, and over writes any earlier stored position.

To activate the MOB function, press the (MOB) button.

A fixed alarm signal will sound briefly to alert the crew. The text (MOB) flashes.

Off course error will be displayed in the main-function.

= steer to port.
