The life you save could be yours (or mine).
The button behind the red flap on the VHF radio is for "emergency" use only. That button transmits the boat location and the "Mayday" call to any boats in the area where the emergency occurs. The DSC function requires you to obtain an MMSI number, and use of this function is taught at the Power Squadron. This button behind the red flap is used ONLY in an emergency.
Thanks to all for the welcome, this seems like a very friendly forum.
Jim, that seems like a long way to go for a course, given that my boat is moored in Wales, but thanks for the thought. I've already done a couple of RYA courses and am qualified to PB Intermediate. I also regularly drive a rib as safety boat in my local sailing club, so, although I am new to the site and to owning a boat, I'm not a complete novice. I appreciate you clarifying that the red button, behind the flap, marked 'emergency' is only for use in an emergency though
