How do I fade my beard with the rest of my hair?

I just bought a facial hair trimmer. I read how it work and everything but one question eludes me. How does one fade his longer hair into a shorter beard? The trimmer I used has a variety of attachments including 6-position guide. I'm wondering if there is something specific I have to do before I try it on myself.

Thanks!

if beard is too long the trimmer doesn't work. if this happen you need a shear and cut beard to shorter. so you can use your trimmer.
