Allocation of System Key Functions
The NT20S allows the allocation of "system key" functions to touch switches. The
system key functions can then be used during operation by pressing the touch
switches to which they have been allocated.
For example, if, when a screen for which buzzer sounding has been set is dis-
played, a touch switch is also displayed, the buzzer can be stopped by press-
ing this touch switch.
To set a system key function for a touch switch, use "Touch SW", "Bit specification"
and "Numeric key" of the support tool.
The system key functions are allocated to touch switch numbers 227 to 230 and
255, as shown below. When a touch switch with one of these numbers is displayed
on the screen, it has the same function as the corresponding system key.
