Error code 0.9

You might have to post a screenshot or photo for this. When do you see this error?

Are you using an RTL515? If so are you sure the error code is from Vector and not the RTL.

Interesting I assumed it was my Power Meter. I do have RTL515 fitted as well am I miss interpreting the fault then

Come to think about it the radar did not work when I rode that day

That 0.9 error code is a warning that the radar is saturated. If you see it again I would check that the RTL is up to date on software and if it is then I would suggest contacting Garmin Support. 

There was another user on the Varia forum reported getting a 0.9 error code

Recently I had a same issue  I was using edge 530

I got for today the first time Error code 0.9

aweatherall what do you mean by saturated?

It is receiving too many returned signals to process. Typically you are passing some type of structure that is reflecting the signal.

So nothing to be worried , and yes something is strange in that area , it happened in the past , but not with this error code, just disconnected  

It is a temporary situation and the unit should recover quickly from it.
