I was hiking this past Saturday, actually climbing a mountain in the Adirondacks, and near the top of the mountain my Inspire 2 started vibrating like crazy. It would vibrate three or four times stop for a few seconds and then vibrate again. This went on for a minute or so. When I looked at the screen all I would see is a fireworks or starburst icon, not in motion or anything, just a stationary icon. I cannot find any reference to this behavior in any manual nor can I find the icon that was being displayed. I was very active at the time and I am sure my heart rate was way up there and I wonder if this was some kind of alert regarding that. It went through this process again but not as long at one point during the hike down the mountain, closer to the top.
