My ventilator gives me this error after replacing the O2 cell, if I install an original cell with serial number >Z39xxxxx the ventilator does not update the serial in the technical state and gives error.
This ventilator have firmware version 2.1.2.
This does not access ventilators with firmware version 2.2.5.
I ask if it was possible to have firmware for software update this ventilator.
Thanks
