NOTE
Programs, parameters, and macro variables are
stored in nonvolatile memory in the CNC unit.
Usually, they are retained even if the power is
turned off.
Such data may be deleted inadvertently, however,
or it may prove necessary to delete all data from
nonvolatile memory as part of error recovery.
To guard against the occurrence of the above, and
assure quick restoration of deleted data, backup all
vital data, and keep the backup copy in a safe
place.
