Mains power supply failure

If the mains power supply fails, Perseus
automatically switches to the internal battery. A
fully charged battery will maintain operation for at
least 30 minutes.
Remaining battery charge is displayed on the
status display.
The breathing system heating is deactivated
during battery operation. The peak inspiratory
pressure PIP may be limited, but it will equal at
least 55 hPa (cmH O).
