7.2 Active alarm indication
When alarms are active the homescreen [Alarms] icon will identify the number
of active alarms in the top right corner. The [Home] icon in app pages can
also be configured to provide an active alarm indicator.
The app pages home icon indicator can be enabled and disabled from the
alarms manager:
[Homescreen > Alarms > Settings > Home button active
alarm indicator] .
When enabled the [Home] icon will turn red and have an exclamation mark
placed inside it.
The homescreen [Alarms] icon will identify the number of active alarms.
7.3 Alarm settings
The alarms listed below can be enabled and disabled and where applicable
alarm threshold values can be adjusted. Certain alarms may require specific
connected peripheral devices or configurations.
Note:
Hardware dependent alarms are only triggered when relevant hardware
(e.g.: sensors) is connected and reporting the data required for the alarm.
• [Dangerous Radar targets] — If enabled, an alarm is triggered when Radar
targets become dangerous. Radar targets are deemed dangerous when
they have the potential to cross your path within a specified distance and
time. For alarm parameters refer to:
p.296 — Dangerous targets alarm
• [Lost Radar targets] — If enabled, an alarm is triggered when dangerous
Radar targets become lost (i.e.: no Radar return from the target has been
received for 20 seconds).
• [Dangerous AIS targets] — If enabled, an alarm is triggered when AIS
targets become dangerous. AIS targets are deemed dangerous when they
have the potential to cross your path within a specified distance and time.
For alarm parameters refer to:
p.187 — Dangerous targets alarm
• [Do not alarm for static AIS targets] — Enables ability to ignore AIS targets
that are considered static (travelling under 2 Knots). Static targets that
become dangerous will still be identified onscreen but will not trigger the
dangerous targets alarm.
• [Guard zone 1] — If enabled, an alarm is triggered when Radar returns
are detected within guard zone 1.
• [Guard zone 2] — If enabled, an alarm is triggered when Radar returns
are detected within guard zone 2.
• [Waypoint arrival] — If enabled, when you arrive at a waypoint, an alarm
is triggered. This setting allows you to specify a radius size for three
types of arrival alarm. When your vessel crosses the specified radius, the
Waypoint Arrival alarm is triggered. The following Waypoint arrival alarms
are available:
–
[Arrival radius] — Used when the MFD is NOT in pilot integration mode
and the Autopilot is in Track mode.
– [Pilot track mode radius] — Used when the MFD is integrated with an
Autopilot and the Autopilot is in Track mode.
– [Search route arrival radius] — Used when the MFD is following a SAR
pattern. Also helpful when race sailing and using Laylines, or when
fishing, as this alarm setting provides a smaller radius to ensure you
don't get alerted too far away from the target waypoint.
• [Interception arrival] — If enabled, during target interception an alarm
is triggered when your vessel reaches the distance specified in [Arrival
radius] .
• [Off track] — If enabled, during active navigation an alarm is triggered
when your vessel steers off track by more than the specified [Cross track
error] value.
• [Shallow depth] — If enabled, when the depth detected by your depth
transducer passes the specified value the Shallow depth alarm is triggered.
