It's worth contacting them, the feed back I am getting is, they will first send you an email saying nothing is wrong and offer you a free service, if you get back and say that's not good enough and you have lost faith in the device and kick up a stink. then they are offering a upgrade, if in warranty its looking likely to be free, if out of warranty then there is a fee.
I have a new Black diamond unit which is the same as the new PIEP's they are upgrading to, its a good transceiver, you could sell it on or have a good spare, great if you ski with new people and they have an old/crap one that they could be searching for you with
