the answer is maybe, here is what i would do: if it does not work at all then take off the battery cover door and at the bottom left there is a little (usually) white square sticker, if moisture has gotten into the device the little sticker will be red. if the sticker is red then moisture is probably your problem and will continue to be, call the warranty dept and they should ship you a new one, they may squawk at the water mark but usually you'll be ok...
