Active Alarms
When an active alarm is received, a flashing popup window is overlaid on the current screen when
an active alarm is received. The popup includes a plain language description in addition to the
standard SPN/FMI (Suspect Parameter Number/Failure Mode Indicator) pair defined by the SAE
J1939 standard. Additionally, if enabled, the beeper sounds as an audible cue.
Standard J1939 abbreviations are used for alarms. MS = Most Severe,
MOD = Moderately Severe, LS = Least Severe.

Alarm List
The Alarm List is accessed by pressing any button while an alarm popup is displayed or by pressing
any of the first 4 buttons to show the button bar and then button 4. Alarms not yet acknowledged are
shown in white on red while acknowledged alarms are shown in white on black. The list also indicates
when the alarm occurred if engine hours are available. The most recent alarm is displayed at the
top of the list. The list can be scrolled using buttons 1 and 2 and alarms acknowledged by pressing
button 3. The Alarm List can be closed by pressing button 5 once the alarms are acknowledged.
An alarm indicator is displayed near the upper right corner of the display as long as alarms are
active. The indicator and alarm messages in the list are automatically removed when the alarm has
not been received for a few seconds.
