8. Some functions may have been implemented at the request of the machine-tool builder. When using
such functions, refer to the manual supplied by the machine-tool builder for details of their use and
any related cautions.
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.
