Backlight Control
Here, three selections (modes) are available.
• Wait
To preserve the GP unit's screen display elements and extend the life of the
backlight, the backlight can be set to automatically turn off after a designated
period of inactivity (idle time) elapses. The factory setting for this item is
[OFF].
• Enable Touch if Backlight is OFF
This setting designates if the touch panel is enabled or disabled when a back-
light burnout is detected. When this feature is set to OFF, touch panel touch
input is ignored, thereby preventing touch panel operation errors. The factory
setting is [OFF]. (Checkbox is not set.)
Backlight burnout detection is performed via monitoring of the backlight's current
consumption. Therefore, certain types of backlight failures cannot be detected.
• Brightness
Four levels of brightness are available.
Setting Procedure
1. In the [Settings] menu, touch the [Offline] tab.
2. Touch the [Backlight] icon.
3. Touch/select the desired backlight brightness.
4. To automatically turn the backlight off after a specified period of time, touch
the [Wait] selection and set the "idle time" period.
