They are speaking of your compression and rebound settings on your forks and shock. Usually a screw type adjuster on either the top or bottom of your forks. Sometimes both. They click when you turn them. In/clockwise for increased compression or rebound, which will result in a harsher ride.Or out / counterclockwise to decrease compression/rebound for a softer ride.
The shock adjusters are sometimes a little harder to find , but they should be there, if so equipped.
