Sensitivity Plus Or Minus

Thank you for taking the time. On my time ranger, the sensitivity plus or minus, does that effect the detector when IM in program mode P1-p4,

When Im in the P1-P4 range does that override all other features?

If so when do you use the sensitivity range,

How do I use the blinker mode, I know I got carried away so if you have any time for any of the questions thanks
