One of my remotes wouldn't work today (number 1 light would flash, stay constant and then go out as soon as I moved it) so I assumed the batteries were dead. To check I took the batteries from the one that was working and tried them in the faulty one, still no joy. So then I put fresh batteries in both remotes, and now nothing works! Doing the standard synch procedure, holding down red button on console and remote as required and on both remotes now all 4 lights on the remote just flash indefinitely (I gave up after about 3 minutes), am I missing something?!
