Before you read this and say, read the instructions, I want to point out there is no mention of this in the instructions.

For some reason, this remote locks itself sometimes, when you press a key, the led flashes twice. Not all the keys work, but most do. When it's in this mode, you can't do anything, you can't control your device, and you can't input codes or access any of the search modes.

My question is, has anyone figured out what this mode actually is, and how to get in and out of it. Or is it more of a fact of I have a dodgy unit? It's driving me mad.
