IMPORTANT ALARM NOTES
Anchor Alarm - The anchor alarm may be triggered even when
you're sitting still. This can happen when using a small (less than
.05 mile) anchor alarm range.
Arrival Alarm - If you set the arrival alarm's distance to a small
number and you run a route (see the Navigate Routes segment),
this unit may not show navigation data to the next waypoint, once
you arrive at the first one. You may not be able to come close
enough to the first waypoint to trip the arrival alarm.
NMEA 2000 Alarms
The NMEA 2000 Alarm can be set to monitor multiple EP-10 Fuel Flow
and EP-15 Fluid Level sensors. You can set a threshold for each alarm
in its corresponding Percent box. Thresholds give you control over
when the alarm will go off. You may want the alarm to go off when the
black water tank is filled to 75 percent of its capacity, likewise, you
may want to know when the fuel level falls below 30 percent of tank
capacity.
