Listen function in control room question.

Hi,
I want to solo one channel while reording and do not want to interrupt the listening for the musicians that beeing recorded. I have tried to use the listen function and read the manual but I do not get it to work…nothing happens when actitivate those buttons…

I am sending via the CUES to the musicians,I have tried pre and after fader I can listen to my mix or one of the four cues but do not understand how to solo listening.
Will some one please guide me how this thing works. Please!
