Standard Horizon HX210 VHF

Just bought one of these and found it turns itself on and off spontaneously (and annoyingly) while in the pocket of my (MsFit) PFD. The power button is just too accessible.

Hey Josko, I have a story to tell about SH and and NRS PFD.

I have a SH HX870 and a NSR Cvest with a radio pocket. The pocket is too narrow for this radio (any radio really) so when I slid it in, the DSC flap on the side got snagged and opened up. Unaware of this, I began practicing rolls which somehow tripped the DSC button. I then start hearing the alarm going off that I have tripped the DSC and try to use my radio to contact the Coast Guard. In a perfect storm of malfunctions, water had gotten into the radio (a manufacturer's defect which got me a new radio) and my radio no longer functioned as a 2-way...I could only hear the alarm and see a read out to cancel it if I wanted to. But because it was wet, it wouldn't let me cancel it. A minute later, the radio was completely dead. 

Realizing that if the DSC actually worked, the CG would be on its way, I raced back into shore (about a 1000 yards), ran up to the house where I was staying, and called the CG directly. The good news is that the DSC worked and they were prepping a helicopter. The better news is that I was able to stop them before they sent it and avoided what would have been an incredibly embarrassing moment -- even though it wasn't my fault. 

As I said, SH replaced my radio free of charge. But I have always struggled to get my radio into the pocket of my Cvest without snagging the DSC flap and thereby exposing the button. Last week, finally gave in and bought a new CVest with a much wider radio pocket. 

And finally, to get back to the point of your post, my radio was off when I went out that day. But the radio has a Water Hazard feature which turns it on if a sensor gets wet. So I presume that by rolling, I triggered that sensor which turned the radio on, and then subsequent to that, I somehow pressed the DSC button by mistake through the pocket. Your radio is a different model than mine, but it it has the Water Hazard feature, and it's on, and you're rolling, that might explain it. Or not.
