GPSPlus ALARMS
The GPSPlus display has alarms that can be set and
adjusted to suit your requirements. When an alarm condition
is met the internal alarm buzzer will sound and the display
will indicate which alarm has been triggered. When the
GPSPlus is part of a fully integrated Network Instrument
system the alarm conditions will be displayed and sounded
by all Network display units.
The following alarms can be set and adjusted:
• Waypoint arrival alarm with automatic waypoint advance.
• Anchor watch alarm.
• HDOP alarm (GPS use only).
• Cross track error alarm.
• Waypoint zone alarm.
The GPSPlus display will also repeat alarms from Network
instruments when part of an integrated Network System.
Refer to the SETTING UP THE GPSPlus for details on
setting and adjusting the alarms.
