I'm not familiar with your detector, but some general tips I can give you is to read and re-read the manual and watch the video if one came with it.....be patient, keep the coil very close to and parallel to the ground learn the signals. Until you're comfortable with the tones, dig everything being aware of the tone of each find. Good luck!
Turn it on and go! No seriously what are you confused about? I have the 505 Pro, still learning it but have been finding some nice stuff. I found a necklace and a nice (but bent) sterling silver ring this past weekend.
