[Setting]
[Operation]
(1) Press the touch switch with the "buzzer stop" function to stop the buzzer.
The NT31/NT31C provides the following two backlight modes.
- Light: The backlight is lit continuously.
- Flash: The backlight alternates between lit and unlit states.
With the NT31/NT31C, the following two methods are used for controlling the
backlight mode.
- Displaying a screen for which the backlight attribute is set
- Operating the PT status control area
with the screen, which is turned off by the screen saver function if the NT31/NT31C
not operated for a while, or by operation at the PT status control area. Even when
the backlight has gone off, it may light or flash according to the setting if the back-
light mode is changed by operation at the PT status control area.
By using this method, it is possible to control the backlight automatically when a
specific screen is displayed.
Set either of the following statuses for the "backlight" screen attribute of the screen
for which the backlight is to be controlled when creating it using the Support Tool.
(The default setting is "Light".)
- Light
- Flash
When the screen is changed over during the operation of the NT31/NT31C, the
status of the backlight is controlled according to the setting for the backlight attrib-
ute of the newly called screen.
