How to revert all the way back to original settings?

For now I wanna turn FnLk off (i.e., I need hot keys not function keys), how could I do that?

If you need to do this frequently, I will modify the code (or do it you self).

For one-time use, restart the keyboard (slide down the power slider for ~ 3 seconds to turn off).
