Backlight

When the backlight timer expires, the touch screen backlight is dimmed, not turned off. When both checkboxes are unchecked, the backlight never turns off (or dims).

The default value for external power varies by Power Configuration Mode (page 5-80)selected (and for Ignition Con- trol, the status of the vehicle ignition). The default value is 30 seconds when operating on the internal UPS battery.
