In this NC unit, the machining programs, parameters and tool compensation data are saved in
the memory (memory elements). This NC unit's memory is backed up by lithium batteries, and
under normal conditions will last 6 years from the date of manufacture. However, data contents
could be lost under the conditions described below.
To prevent data loss, output important programs, parameters, etc., to a serial input/output device
and save them. Refer to Section "III-8 Maintenance Functions" in this manual for information on
how to do this.

Data in the memory can be lost under these kinds of conditions.
(1) Incorrect operation
Data can be lost if the operator inadvertently changes data while editing a program or setting
parameters.
(This is not really a data loss, but it is a loss from the standpoint that the original data is gone.)
Data can be lost if the operator inadvertently deletes data or initializes NC unit.
(2) Battery life expires
When the battery life expires and there is not enough voltage to store the data in the memory,
data can be lost by turning the power OFF.
(3) Faults
Data can be lost when faults occur and the control unit must be replaced.
