•
The AC POWER indicator on the top left corner of the ventilator illuminates.
•
The INTERNAL BAT indicator flashes while the battery charges and then turns off
when the battery is fully charged.
Refer to Figure 4-4 on page 4-4.
If the AC power cable becomes disconnected or the AC power source fails, an “AC POWER
DISCONNECTION“ alarm signals an automatic switch to the external DC power source (if the
DC power cable is connected) or to the ventilator’s internal battery.
One of three power indicators, located on the upper-left of the ventilator’s front panel, illuminates to
signal which of the three possible power sources are currently in use by the device (refer to
Figure 4-4 ).
Note:
The only time the AC POWER and INTERNAL BAT indicators are illuminated at the same time is when the ventilator
is connected to an AC supply and the battery is charging (INTERNAL BAT indicator is flashing).
