2.6 Final inspection before delivery
2.6.1 Function check
1 Connect the power cord to the power socket of the PV 101+/PV 102+.
2 Connect the patient circuit.
3 Start the PV 101+/PV 102+ and check that it functions normally.
4 Disconnect the power cord and check that the power failure alarm sounds. Recon-
nect the power cord. The alarm should be silenced.
5 Switch on the PV 101+/PV 102+. Upon starting, all the LEDs on the front panel
