If it is impossible to keep the chosen air-flow, you
will hear an acoustic signal. If it is possible, the
electronics will automatically decrease the air-flow
by one level. If the unit is unable to keep the lowest
practicable air-flow, you will be warned by alarm
and the reason for this alarm as well as the in-
structons for needful intervetion into the unit will
appear on the display. Next it is urgent to stop work
immediatelly and to replace the filter or battery,
