Alarms and Limits
Medium Priority Alarms
Medium priority alarms signal potential problems with the equipment or other non-life-threatening
situations. Medium priority alarms are indicated with slowly blinking amber displays on the Main
alarm LED and the appropriate indicators or numeric displays. An error code may display to
identify the error source. See table in Error Code Section.
Medium priority alarms are: 3 beeps and a 25-second pause. This sequence repeats until the
alarm is cleared or silenced. The following table describes alarm conditions and visual indicators.
Watchdog Alarms
Watchdog alarms are loud, two-tone, steadily beeping signals that indicate a hardware or
software malfunction. When a watchdog alarm is activated, it can be cleared by shutting down
the device. If the watchdog alarm does not clear, remove the battery and contact your distributor
or Nonin Technical Service.
Informational Tones
Informational tones are at startup/initialization (speaker verification) and the pulse rate tone (which
changes in pitch with SpO
2
values). They are typically single “beeps” or a series of 3 “beeps.”
Reviewing, Setting and Changing Alarm Limits
NOTE:
Alarm limits reset themselves to default values each time the device is turned on,
unless the device is in Patient Security mode. In Patient Security mode, alarm limits and
volumes cannot be adjusted; they can only be viewed.
