Monnal T75 user manual
Note:
During a total power outage (AC power, external and internal batteries) the alarm
threshold settings are retained in memory and may be displayed after the electrical power is
restored. The settings are saved by a backup battery with a life of approx. 2 years. An alarm
is issued when the battery life becomes too short. The battery must be replaced. A power
outage of more than 2 years will cause the settings to be lost. At the next startup, the alarm
thresholds will be automatically restored to their default values.
MVe low threshold settings
In PSV NIV mode, the user has the option of setting the lower threshold of the expiratory minute vol-

This setting is used to inhibit the alarms associated with the low expiratory minute volume (MVe) par-
ticularly in the event of non-invasive ventilation with major leaks.
