ALARMS
4.5.4 SENSOR FAULT
If a sensor fault occurs in CSM mode, the instrument’s
audible alarm will activate. The visual alarm (yellow and four
red LED’s) will also activate.
If a sensor fault occurs in CGI mode, only the visual alarm
(yellow LED) will activate.
In both modes, a warning display is followed by a display
showing a spanner symbol adjacent to the faulty range, as
illustrated in Shipsurveyor 3 example, Fig. 4-10.
