I just received my Bel 970 detector back from Beltronics repair and on the service order they indictated that they replaced the antenna and updated the software on the unit.
I plugged my detector into a 12 volt power supply and it started up fine but when I went to switch from highway to city mode all of the sudden I get a L03 PLL Lock? message and then a "Messages" message followed by the repeat blinking and beeping of the PLL Lock L03 problem.
That was the whole reason why I sent the unit in the first place. What's even more bizarre is that it seems that everytime I change power sources (from a benchtop 12volt supply) to a car it gives me that error message.
If I shut it off an reboot then its perfectly fine.
What is a L03 error exactly anyways?
