Sirius remote code

[FritzL]

Trying to teach my Onkyo 705 to On/Off the Sirius Starmate 2. So far the remote indicates it's learning the power key, but it isn't working.
Anyone know the remote code for the Sirius SM2?

I had this problem with learning the power button for my Dreambox into the Rotel remote control.
There's a chance it'll work after trying many (20) times. Some codes seem to be difficult to capture.
