Alarms are another diagnostic tool provided by RapidZone.
Critical system parameters are constantly monitored within
the RapidZone application. Any deviation outside of preset
limits will trigger an alarm. The RapidZone Command Display
indicates an active alarm by sounding an intermittent beep
and/or by flashing the !! indicator. Active alarms can be dis-
played by pressing the Alarms softkey.
NOTE: Once the conditions that triggered the alarm have
been cleared, a second alarm is issued with the orig-
inal text preceded by RTN (return to normal).
