What the hell is going on here? I bought a BRAND NEW Beltronics Vector 965 with the M4 platform and it was working just fine for the 1st week of use. Then this morning, the display starts blinking and it says "self cal" for a few seconds and then it starts beeping and says "service required". WTF???? I NEVER dropped it, I never left it in the sunlight(didn't have it long enough to do so). Is this a hardware problem or a software/firmware? It's version 6.1 If Bel updates it to 6.3, will the "service required" notification go away? I did a reset and it reseted successfully but then seconds later, same message. This is so disappointing. As soon as Bel fixes this, I'm going to sell it and get a Whistler XTR-695. I am also getting rid of my Bel STi Driver because it's only a matter of time before that starts with the "service required" notification. My pro78 has been very reliable since I've owned and I love the fact that it has a 3 year warranty.
