2.6 Heading Sensor Selection
• CAUTION - System Selection
• Heading sensor selection (switching) may cause a large change of True Heading. When on automatic
steering, first turn the steering mode of the automatic steering system to "MANUAL" to prevent a large
course change. Confirm the area around the ship is clear and turn to "AUTO" steering again.
Normally the Gyro Compass is selected as True heading senor. If an external heading sensor is connected to the
AlphaMidiCourse Mk2 it is possible to switch between Gyrocompass and External heading sensor. An external heading should
only be used when the gyrocompass is not working properly.
1.
Turn "OFF" Analog repeaters
Note
When the repeater is a serial signal type, this operation is not required, because it will synchronize
automatically. However, confirm that the value displayed coincides with "the True Heading" selected by this
system, after the repeater switch is turned "ON".

By pressing
GYRO
or
EXT
together with
ACK/ENT
switch the AlphaMidiCourse Mk2 will toggle between using the
gyrocompass or an external sensor as active sensor.
Note
When an active sensor is changed, an audible alarm will sound three times. The active sensor will be
identified by a green led in the top right corner of the GYRO or EXT button as shown below.
