displayed in the alarm area of the monitor while technical alarms and prompt messages unable to trigger alarms are
then displayed in the information area of the monitor. This section does not describe the content about Arr. and ST
analysis.
Among physiological alarms, those belonging to the type that the parameter has exceeded the limits may activate the
recorder to automatically output the parameters and related measured waveforms when the alarms occur on the
condition that the alarm record switch in the related menu is On.
Tables below describe respectively the possible various alarms those may occur during the measurement.
Physiological alarms:

Alarm level
ECG LOST
No ECG signal of the patient is detected.
HIGH
HR TOO HIGH
HR measuring value is above the upper alarm limit
User-selectable
HR TOO LOW
HR measuring value is below the lower alarm limit
User-selectable
