     support is provided by the oldest available version after the specified version. Refer to the user's manuals for the
     specific Units for the relation between models and versions.
*2 The instructions for time stamp refreshing are supported by CPU Units with unit version 1.06 or later. If you do not use
     instructions for time stamp refreshing, you can use version 1.05. Refer to the NJ/NX-series Instructions Reference
     Manual (Cat. No. W502) for details on the instructions for time stamp refreshing.
