Use this function when the system program of the NT631/NT631C has been
corrupted, or when installing a new system program.
Reference: • In order to install a system program, the system installer must also be
installed at the Support Tool. The system installer is an accessory with the
Support Tool (NT-ZJCAT1-EV4). When installing the Support Tool in a
personal computer, install the system installer also. For details on the
method for installing the system installer at the Support Tool side, and the
operating procedure, refer to the NT-series Support Tool Ver. 4.@ for Win-
dows Operation Manual (V061-E1-@).
• When the system program is cleared by mistake, it becomes impossible
to use the NT631/NT631C at all. Check that the system installer is
installed at the Support Tool side before deleting the program. However,
note that the registered screen data and memory switch settings are
retained.
• It becomes possible to install the system program inside the Memory Unit
automatically by installing the Memory Unit at startup (Refer to 3-5 Using
a Memory Unit).
