Hi Wondering Geo,
Your meter might be in hibernation mode – is it brand new or have you used it before?
If it’s in hibernation, you can bring it out of hibernation by connecting the “C” and “Ω” inputs together and holding them together for 10 seconds. The meter will reboot (you will see the orange flashes again) and then the Mooshimeter’s radio will be on. There should have been an instruction card that came with your meter.
Let me know how it goes, best
