New PS2 wirelsss controller wont work?

[Rooboy2]

Hi, I was hoping someone might be able to help me with a problem.
I have got a new PS2 wireless controller ( replaced one that I wore out)
However with the new one, I plug in the module into controller section of PS2 unit, and have fresh aaa batteries in controller.
Yet when I start PS2, it is not detected and nothing happens when I turn the controller on. Or if I press the start button on the controller.
The recever module has one constant green LED light showing and the red one is flashing, is that correct? I can't remember what the one I wore out did, too long ago.

What have I not done or what might be wrong?
Thanks in advance

Yes, two of them.
one is on/off the other on is Virbartion on/off

I've tried it with just power on and with both buttons set to on.
Got brand new batteries in it.
