AirNote error code - 510

Hello!

I am currently trying to troubleshoot an AirNote sensor. On powering up the sensor, it displays the typical “Lobat” message upon start-up. Then a count-down from 5 is displayed. After this, there is what I assume to be an error code of - 5 10 displayed for about a minute.

From what I see here, this indicates general failure. Are there any steps I can take to troubleshooting the sensor, or does it require a full part replacement? Any advice is much appreciated!
