8. ERASING MEMORY
GSM-19 version 6 magnetometers are equipped with flash memory chips. Flash memory cannot be
partially erased. The technology requires that the memory chips must be erased all at once.
For this reason, it is not possible to remove single files from the memory. To erase one file you
must erase them all.
When flash memory is erased, all the information is overwritten with "blanks". Once erased, the
data CANNOT be recovered.
IMPORTANT NOTE:
Use this function only if you want to clear the entire memory, since all of the
files is erased.
As a security feature, to prevent accidental data loss, you must press two buttons simultaneously to
access the erase menu and to later confirm whether to erase the memory or not.
