Note:
The data sets that have been recorded are wirelessly transferred to the
PC using the USB transceiver. The average transfer speed is 20 data
sets per second. In extreme cases, it can take almost 45 minutes until all
data sets have been downloaded (when the memory is completely filled).
During radio-clock reception, communication with the USB receiver is not
possible and is interrupted. When reception is successful,
communication is automatically restored again.
