Note:
If the ventilator had been previously stopped by use of the I/O switch while ventilation was in progress,
the ventilator starts directly in ventilation mode and does not show the Welcome Menu screen.
The Alarm, Technical Fault, and Event logs are stored in non-volatile memory on the Main CPU PCB,
ensuring that the information is retained when the ventilator is powered off and during power loss
conditions.
