When the ventilator is on, the On/Standby LED will be on. The ventilator will operate on external
power if it is available or internal battery if there is no external power or the external power source is
depleted. The internal battery will be charged from the external power source while the ventilator is
operating on external power.
When the ventilator is in Standby, the On/Standby LED will be off, however, the internal battery will
continue to charge when external power is connected.

If both the Leak Test Query and the Patient Circuit Mode Query are disabled/off when the ventilator is
powered up and passed Power On Self Tests (POST), the ventilator will begin ventilation using the

activation are suspended and the message NEXT is displayed (see Queries in Chapter 10 - Extended
