6.6. Alarm
Alarms are used to alert the user
to a hazard or situation requiring attention. The IS20 allows
the user to set up alarms for navigatio
n data from the Alarm page. Audible and visual warnings
are triggered based on the specified thresholds of the alarm. This can be used to monitor all the
input data within a safety range. So, you can feel relax during sailing.

To set up an alarm, the data type has to be selected first. The current firmware supports the
following data types:
Depth, SOG, COG, heading, bearing, TWS, TWA, TWD, AWS, AWA, water temperature, water
speed, ROT, XTE, TBS, roll, pitch, current, voltage, battery status.
After selecting the required data type, the comparator (>, = or <) and the desired value has to be
added to the alarm rule. The final step in activating the alarm is to toggle the switch on the right to
the ON position. If the alarm is no longer needed, it can be easily disabled at any time. When an
alarm is triggered, a warning message as the one below will appear on the IS20 screen, alerting
the user to the out-of-range condition.
