Hi Ingo,
This question of the A-136 has come up several times in the past -
it is quite a tricky module to get to grips with, and matters aren't
helped by the manual not being as precise as it could be.

Check out posts #307 and #1172, but read them carefully! For my money
it is much easier to understand this module if you have an
oscilloscope, but Joe (author of #307) proved it was possible with a
simple meter, a good ear, and lots of patience!
