75%
75% battery life remaining, does not need to be replaced.
50%
50% battery life remaining.
The conditions of use of the battery must be taken into consideration when deciding
whether to replace it or not:
If the battery is never used apart from in the test (permanently connected to the AC power
supply, back-up supply), the remaining battery life may be sufficient.
If the battery is used often, during intra-hospital transfer of variable duration, it may be nec-
essary to replace it.
25%
The battery has reached its operating limit.
Please replace it.
In order to preserve a record of the test performed, the information is permanently displayed next to
the
[Battery test]
access key, and includes remaining battery life and test date.
Note:
This test resizes the battery charge indicator displayed on-screen: for example, if the
battery is down to 50% of its initial charge, no more than three of the five pictogram cells can
be lit. This function keeps the user aware of the overall state of the battery.

Servicing once a year and checking the operation and performance of the unit.
The ventilator counts two operational parameters: number of hours of ventilation, and number of
hours that the machine is powered up.
These times can be viewed at any time in the stand-by screen.
The internal battery must be replaced after 500 charge/discharge cycles or 3 years (whichever comes
first), and this replacement must be performed by a qualified technician. For more information, refer to
the maintenance manual.
11.3 O2 cell
Note:
The working life of the O2 cell is approximately 5000 hours, but this can vary according
to the oxygen concentration used and the ambient temperature.
