Battery
The very low energy consumption of the device means that a battery service life of up to
5 years is possible. The current charging level of the battery is shown in the device's digital
display. If a critical charging level is reached, the device also sends this condition as part of
the "Extended Status Byte" to the host control system.
Other repair or maintenance measures are not required on the device. You can find
supplementary information on this under Inserting / removing the battery (Page 28) and
Alarm, error, and system messages (Page 79).
