Default Where is tachometer calibration screw in 944 S2?

I need to calibrate my tachometer after its replacement. For every real 800rpm it displays 1000rpm.
To explain it in other words left side is the tacho value, right is the real engine rpm:
3000 - 2400
4000 - 3200
5000 - 4000

Where is tacho calibration screw? I know that there is one, but don't know which one is it.
