Loss of Gyrocompass signal
When the compass signal is lost, the presentation mode automatically becomes head-up and the
HDG (heading) readout at the top of the text area shows asterisks ***. Also GYRO appears in
red characters at the lower right corner on the screen. When the gyrocompass signal is restored,
the SET HDG appears at the upper-right corner on the screen. Press the MODE key, and the
asterisks and GYRO go off. Align the HDG readout with the gyrocompass reading, referring to
the previous section 1.8. Finally press the CANCEL key to erase the message SET HDG.
