The display returns to correct depth after 8 seconds.
Note: When the ST30 Depth is used in a SeaTalk system, illumination may
be adjusted from any instrument.
The ST30 Depth is equipped with visual and audible shallow and deep
water alarms.
Both of these alarms are set in calibration (see section 6.3).
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.
The 'feet or metres' legend flashes whenever the depth signal is lost.
