On Windows Mobile devices, reading the default value returns the Battery Power Backlight On-time value 
of 30000. However, when setting the backlight value, it is written to the External Power Backlight On-time 
value which enforces the range of 60000 - 600000 for that parameter (1 minute to 10 minutes).
