LI Falses

I have ran the LI since September and I love it. Has saved me out of numerous tickets. But in the last two days I have been getting numerous falses from the LI. I don't believe I have had any falses until now. I counted 8 falses yesterday and 12 today. It usually says unknown gun or occasionally it says something that I can't make out but it is two syllables and starts with an R, it sounds like Ruby or something. I have not changed anything since the initial setup. I know I would occasionally get a false laser alert from the V1 due to the sun, but today was overcast and it was happening both times I was driving today, from 10-11 and around 4-5.

Any ideas what is causing this?

thanks,
