2.9 Alarm Setup Menu
You receive warnings of hazards via built-in alarms that are generated for each
application. If an alarm is generated, it sounds an audible warning and displays a
message box on screen that explains the cause of the alarm. In some cases, the
appropriate action is taken. For example, following an arrival alarm, the next
route leg is activated (if Waypoint Advance is set to AUTO).
The Alarm Setup Menu is divided into these sub-menus:
• Navigation Alarms Setup
• Fishfinder Alarms Setup (described in the DSM25 Handbook)
Note:
To silence any alarm, press any key.
Navigation Alarms Setup
Navigation alarms will sound in any application when you are navigating.
