920 & 922 exterior difference?

[jtv]

Can anyone tell me how to determine if a receiver is a motorola 920 or 922, from the exterior? I can't find a number or name on a unit I found.
thanks!

The front of a 920/921 says digital satellite receiver, the 922 says dsr 922, also the back has two sets of rca jacks on the 922 and the 920 has one, look in the back mite be by the plug the model number will be listed real small writing white sticker.
