9. Maintenance
9.1 Battery Operation
If ´bAt´ is shown in the secondary display the battery has been used up and
needs to be replaced. The device will, however, operate correctly for a certain
amount of time. If ´bAt´ is shown in the upper display the voltage is too low to
operate the device; the battery has been completely used up.
The battery has to be taken out, when storing device above 50 °C.
Please note: We recommend taking out battery if device is not
used for a longer period of time!
