1: I saw the P sign and pressed the P, but in the end, it told me [failed to operate whistle].
I should press the P before or after the P sign? Should I press the P twice every time?
2: I drive the train at 140km/h under PZB O, the yellow triangle tells me the speed limit will be 100km/h, I decelerate the train, but the train has an emergency brake in about 15 seconds.
Maybe I decelerate too slow, but in the end, it told me [Indusi 2000Hz], Doesn't the 2000Hz magnet appear at the red light?
3: What does the F sign near the railroad means?
4: In the main menu, I can't see the detail information on the right, and I have re-install the Zusi from Steam.
