Level alarm:
When the actual level is outside the allowed range, an alarm message will be displayed at the
bottom line of the display indicating the type of alarm: "LO LEVEL ", "HI LEVEL" or
"HI-LO
LEVEL".
The alarm is terminated automatically as soon as the level is in its range again. Due to the
setup configuration it might be that the level is outside it’s range without an immediate alarm.
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 official
batteries may be used, or else the guarantee will be terminated. The remaining lifetime after
the first moment of indication is generally several days up to some weeks.

Alarm 01-04:
