I have a digital elite helmet, perhaps 6 months old. It is randomly "freezing" in the darkened mode. Once this happens, none of the buttons will do anything. The only way I can figure out how to reset it is to remove the lens and pull out one of the batteries. Its a pain. This happens to me at least 2-3 times during a full day of work. Has anyone experienced this? Is there a fix easier than pulling out the battery?
