CAUTION!
The device contains a buffer battery that is used for data buffering when the device is in switched
off mode or if the power fails. The operating life of the battery is at least 7 years. A low battery is
indicated by the battery pre-alarm ("Battery low"). An empty battery is indicated by the battery
alarm ("Battery empty").
If the battery is not changed in time, data may be lost!
The battery must be replaced within 4 weeks after the battery pre-alarm has been triggered. The bat-
tery change must be carried out exclusively by the manufacturer's service department. For this pur-
pose the device must be sent to the manufacturer.
