Perreaux R200i owners

I don't know if you ever got this fixed, but

A) Congratulations on the R200i.  I sold mine years (like 2011) and to this day I regret it.  I loved that integrated.

B) I had a similar issue with the remote.  Someone dropped it and broke the pins connecting the antenna to the circuit board.  Had a co-worker solder it back to the board and that did the trick.

Check the batteries they may have enough juice to light the buttons but not enough to send the signal.  A multimeter can check the voltage.  If in doubt, put in new batteries and try it.
