SN of the receiver, DDD is day of year, and NN is the recording session.
WARNING – The static data will be saved in the first logging session, the “record_1”
folder, by default. Old files will be deleted if the storage space is full. If you configure not to
auto delete old files when the memory is low, the receiver will stop data logging.
