Chapter 5: Backlight
Backlight Configuration Parameters
Psion Teklogix Mobile Devices SDK Developers Guide 31
On Psion Teklogix computers running Windows Mobile, the display and keyboard backlight time-
outs are not controlled independently; instead both are controlled by a single timeout value.
However, there are still two timeout values which may be set; one for when the computer is
running on battery power, and one for when it is connected to a constant external power source.
5.2 Backlight Configuration Parameters
The following universal methods are available in all development languages for getting and
setting backlight configuration values—see the API Reference Manuals for the name of the
method in each development environment:
• Get a boolean setting.
• Get an integer setting
• Set a boolean setting.
• Set an integer setting
The following table lists the ranges of values and the default values available for each
