21. BATTERY LEVEL

If the battery level in the base station or in the wireless sensor reaches a
critical value, the low battery symbol appears in the respective area on the
display. When replacing a set of batteries, always remove the batteries from
the other devices and reinsert them in the correct order. Replace the batteries
to be changed with a completely new set with full capacity. This ensures that
the connection between the devices is correctly re-established.
