In order to install a system program, the system installer must also be installed
at the NT Support Tool. The system installer is an accessory with the NT Sup-
port Tool (NT-ZJCAT1-EV5). When installing the NT Support Tool in a person-
al computer, install the system installer also. For details on the method for
installing the system installer at the NT Support Tool side, and the operating
procedure, refer to the NT-series Support Tool Ver. 5 for Windows Operation
Manual (V070-E1-
j
).

When the system program is cleared by mistake, it becomes impossible to use
the NT21 at all. Check that the system installer is installed at the NT Support
Tool side before deleting the program. However, note that the registered
screen data and memory switch settings are retained.

The system program in the Memory Unit can be installed automatically by
starting the PT with the Memory Unit installed. (Refer to 3-5 Using a Memory
Unit.)
Clear/install the system program by following the menu operation from the Sys-
tem Installer mode menu shown below.
