What happens when the tracker memory fills up? How can I tell if the tracker is in overwrite?
Records on all trackers are overwritten, from oldest to newest.
a) ST820: The diagnostics panel will indicate whether the device is in rollover.
b) ST825: If you download an original copy of records the 1st event should always be that the memory was
cleared. Check the record range to see if it is ~250K.
c) TG-1XX/3XX: A USB download will show the 1st record as the memory being cleared. Its memory should
also be ~500K.
