5.6 Using Batteries
A battery is intended as a backup power source if the primary mains power
source fails.
Power Source Priority
1
Mains power
2
External DC
3
Internal battery
When a power source fails, the Vivo 40 will switch to either the internal or the
external battery if installed and show a message in the display window.
Internal Battery
The internal battery can also be used as a temporary power source for transpor-
tation between one stationary power source to another.
When running on battery, the bat-
tery status is indicated by the fol-
lowing symbols:
Full
Medium
Low
Empty
The internal battery is dis-
connected or malfunction-
ing.
Using the HA 20 humidifier while operating on a battery significantly decreases
the battery operation time.
Due to the internal battery, the Vivo 40 may start if the Start/Stop button
is pressed accidentally, for instance, when packing the ventilator in the
carry bag. Make sure to place and pack the device in a way that prevents
unintentional start of the machine.
