U can verify the machine cuts out when on a slope when u lift up at around ten feet...Then, if you want the tilt to read center...go into analyzer access level 2...take note of all current settings..Then change the model and at least one other option, enter and back out, kill power, then turn on and verify its reading the other type of machine and whatever else you changed...then change those back, enter and kill power, then go in and verify everything is set the way you want, then check tilt and angle calibration...should be reset
