Hi all, I see 7 green quick flashes when booting up. So, initially there is the self-check sequence, then it starts looking for satellites with three, then two, then one red light, and finally, only green. During this procedure, at two steps it gives off seven quick green flashes. I've read those are "save course lock" (after 30 seconds of powering up) and "save home lock" when more than 6 GPS satelites are found. Is it so? Want to be super sure.
