Tip – For hcn files, the name of the file is represented as XXXXXXDDDNN,
where XXXXXX is the 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.
