14. Back-up Battery Charging
Prior to first use, the ventilator should be connected to a suitable power outlet that
is ON for a minimum of 24 hours. The ventilator does not need to be turned on to
charge the battery.
The ventilator will indicate that mains power is present via the indicator LED on
the front of the machine.
It is recommended that the ventilator has its batteries charged every 14 days. The
ventilator must be connected to a mains power source for 24 hours to ensure a
full charge.
If the ventilator has not been used or charged in a 40 day period, it must be
charged for 24 hours. Failure to do this will leave the batteries in a deep
discharged state.
Warning: Allowing the batteries to remain in the deep discharged state will
shorten the service life of the batteries and the amount of time the ventilator
can remain on battery power.
Warning: If the ventilator is operating on battery power and allowed to
completely discharge the battery, it should be recharged a soon as
possible.
14.1 Battery indicator
Version 4.3 software now displays two new icons in the top left hand corner of the
screen.
The first is the battery status icon (A) and the second is the mains power
connected icon (B). The battery status icon operates in two different ways,
dependant on model of ventilator. The mains power connected icon functions the
same way on all models of ventilator.
When mains power is connected, the ventilator displays the mains power
connected icon.
When mains power is disconnected, the ventilator displays the mains
power disconnected icon.
