Coffee Grinder White

What do the dots (1 dot, 2 dots, 3 dots) mean on lid of a Braun coffee grinder?

I have a Braun coffee grinder with no owners manual. It is very simple–no settings, white… The lid has dots, as if it’s measuring something. What is it measuring? How many ounces? Cups of coffee? If it is measuring cups of coffee, is it whole bean measurement or after grinding measurement? I can not locate the product manual online either. We have a 12 cup coffee maker at work and I want to make sure I am using enough coffee!! I use a french press at home, so am not familiar with how to measure coffee for 12.

it could be nothing. I can’t imagine a grinder measuring anything except possibly the coarseness of the grind.
