The experienced mode is just minimum SAFE, full control surface movement and less expo with no angle limiter or self level, see below.
If you set your transmitter up properly (see instructions) you don’t need to use the jumpers on the receiver, it is by default set to all three modes, you just need to put a switch to the correct channel on the TX to control it. Position 1 is usually full safe, 2 is intermediate and 3 is expert. The little switches just alter what modes are sent via that channel.
