From the channel menu, select the stations one by one.
The first wave is the P. Move cursor to start of the P and press P.
The S wave is usually more difficult. It is often the larger wave that comes after the P.
If you can see an S, Move the cursor to the start of the S and press S.
If the S is unclear, go to the next station.
(At least one S in necessary in the current version of Waves.)<\/p>\n\n\n\n
