Indication of battery capacity in 25% increments.
Accuracy of the capacity indication The indicated capacity is determined by the battery
itself. The accuracy depends on the type and manu-
facturer and may deteriorate with frequent partial
discharge and during operation in extreme tempera-
tures. The internal battery is only reconditioned after
being discharged completely and recharged at room
temperature 25
o
C.
The criteria for the warnings !!! Int. battery dis-
charged and !! Charge int. battery are therefore
based on measurement of the battery voltage. The
capacity indicated at this moment may differ from the
actual capacity of the internal battery.
Battery storage time The internal battery must always be removed from
the ventilator for storage and recharged completely
after 12 months at the latest (e.g. in the external
battery charging station).
