Press and hold the M button. A screen with P1 to P5 will appear. Use the left and right arrows to move between P1 and P5. Press the M button again when you have reached the number you want. Now set all your parameters. (sensitivity is the first one) Now they will stay with that preset. I have mine set as the least sensitive on P1 and the most on P5. It will even register dry fire.
Thanks!
