The display returns to current speed after 8 seconds or when
speed key is pressed.
Note:
When the ST30 Bidata is used in a SeaTalk system, illumination may
be adjusted from any instrument.
5.4 Alarms
The ST30 Bidata is equipped with visual and audible shallow water and
deep water alarms.
Both of these alarms are set in calibration (see section 6.1).
Any button press will silence the 'Shallow' alarm. However, the 'Shallow'
indicator will continue to flash until the depth exceeds the alarm value.
The 'Deep' alarm sounds when the 'Deep' setting is crossed either when
going from shallow to deep or deep to shallow waters. Any button press
will silence the alarm.
Loss of signal
The 'feet or metres' legend flashes whenever the depth signal is lost.
