Roamio Remote becomes non-responsive

...when I try to input codes so that it will work my receiver. I did my TV okay, but then I enter certain codes and try to test them, the remote just stops working, no indicator light on top at all. I have to pop the batteries out for it to wake up.



I have just received this Roamio Pro. It's a refurb unit. The Roamio works fabulously, but the remote has this one issue. Works fine otherwise.



For the record I have a Yamaha RX-V765 Receiver.



Anyone hear of anything like this, and know a possible remedy? Should I tell tivo and try to get the remote replaced?



Thanks!
