NOTE
After switching on, the warm-up takes a
maximum of 30 minutes (typically
15 minutes). After switching on, the heating
and the water vapor saturation of the
respiratory gas will steadily increase in
order to achieve an optimum value.
The current intensity of humidification is
indicated by an LED.
5.6 Turn off the base
unit
The humidifier can be turned off using the
power switch, after the end of the therapy.
After switching off, the device should cool
for at least 30 minutes before it is packed or
transported.
6. Mode of operation
The device independently recognizes the
connected equipment at the start, and
will automatically begin the associated
operational functions, without the need of
additional setting being done by the operator.
The device is set via a simple two-button
operation. Thereby, the operation mode, the
current state of the humidification intensity
and the alarms are displayed via a light
emitting diode. An Alarm Mute Key is used
to temporarily interrupt the audible alarm. If
the cause of the alarm is not resolved within
10 minutes, the unit switches to the "OFF"
mode.
A detailed description of the controls and
indicators can be found under Chapter

9. Representation of the Guidelines
10. Alarms
The device can be operated in three modes,
which arise from the various combinations
of features of the optional use of inspiratory
heater wire and temperature probe. For
dynamic adjustment of breathing gas
conditioning to the ambient temperature, the
device is equipped with a room thermometer
that optimizes control.
