Signal mode
The alarms are processed and transmitted by Nav Box to the display based on data read by the NMEA
2000, SAE J1939 and NMEA 0183 networks or the connected analog and digital sensors. The alarms
concern the engines on the network and other navigation parameters.
When an alarm is triggered, the pop-up with the alarm description appears on the display, the buzzer
sounds (if enabled) and the indicator light for the alarm type appears on Nav Control (see "Signals on
Nav Control" below).
All active alarms appear in the ALARMS > Active alarms page.
Note: an alarm configured as disabled is ignored and will not appear in the alarm list. The alarm signal is
inhibited during device configuration.
