Low-battery alarm
When the battery voltage drops, it must be replaced. At first "low-battery" will flash, but as
soon as it is displayed continuously, the battery MUST be replaced shortly after!
Only original batteries supplied by the manufacturer may be used, else the guarantee and
liability will be terminated. The remaining lifetime after the first moment of indication is
generally several days up to some weeks.
