ALARMS

The ConchaTherm Neptune has two alarms conditions: priority and cautionary. Priority alarms are
indicated by a red status light and an audible alarm. Clinician involvement is required to reset a
priority alarm. To reset a priority alarm, turn the unit's power OFF, correct the alarm condition and
turn the unit's power ON. Cautionary alarms are indicated by yellow status light and an audible
alarm. The cautionary audible alarm can be silenced by pressing the alarm mute button. The alarm
will deactivate if the alarm condition self-corrects.
