Hi Bad Mika,
You can try use the RX-442DS on "static" first and see what happens.
But I've been told that the RX-442DS is new receiver able to work with the new tx module from the M11"S" only. So I doubt it could work fine with the TM-221DS.
So try static first and if it doesn't work clearly, you will just have to send it back to where you get it.
Hope it will help you.
Cheers
