6-3-3 Operations with the System Menu
This section describes how to use the menus, including how to call the System
Menu, how to call the System Installer mode, and how to select menu items.
The System Menu can be displayed by either of the following two methods.
• Touching the corners of the touch panel
• Pressing a touch switch that displays the System Menu
Reference:
S If display of the System Menu is disabled by the setting made in the System
Installer mode, the System Menu cannot be displayed (this does not apply if an
error has occurred).
S At the same as the System Menu is displayed, the operation of the
NT31/NT31C stops and the RUN LED goes OFF.
Touching The Corners of The Touch Panel
When two of the four corners of the touch panel (see the figure below) are
touched simultaneously, the System Menu is displayed.

Note that the touch switches used to call the System Menu are not displayed at
corners on the screen. If a touch switch displayed in a corner is pressed first, the
touch switch will function and the System Menu will not be displayed. In particu-
lar, when the touch switch has switch screen function, as a result of screen
switch over, it means the corner is not pressed even if it is kept pressing. To suc-
cessfully call the System Menu, first press a corner where no touch switch is dis-
played, and then press any other corner regardless of the presence of a touch
switch.
Reference: With the NT31/NT31C, the System Menu can be displayed even if the screen has
touch switches registered at all four corners.
Pressing a Touch Switch That Displays The System Menu
There is a control key that has the function of displaying the System Menu.
By registering the touch switch for System Menu display ([MENU]) on a screen
when creating it, the System Menu can be displayed just by pressing this switch.
If the NT31/NT31C has no system program installed, or if the system program is
destroyed, the System Installer mode is automatically established when the
power is switched ON.
To establish the System Installer mode in order to install a system program or
make settings for data management, either turn the power ON, or reset the
