SeaFrogs SF-02 light

I received my SeaFrogs SF-02 light today. It appears functional; i.e., it come on and goes through the colored lights and back to white. However, I have a few questions and the manual doesn't provide much input.

1. When I turn the dial the number in the right window changes from 1 to 9 but the light intensity stays the same. Isn't it supposed to change from dim to brighter?

2. It is very unclear to me what I am supposed to do with respect to Setting 1/2/3 and how I know what setting mode I am in.

Does anyone have a clearer description of this lights operation and modes than the manual provides?

Thanks for your help,
Rick
