Board received without ordering it

We did receive few weeks back some replacement board and I suspect they are for this device:
I would like to know why we received them since we didn’t have any discussion about that…


Hi Frederic,
We encounter a manufacturing defect. We were not sure who was impacted and who was not so we sent replacement to all the users.


Hi Anil,
And can I know what’s supposed to be the problem cause we do have a problem with one captor (doesn’t work anymore even after we changed the batteries)…

can you share the board picture ?

There’s the pictures:

Yes, this unit is impacted.

Thanks for your help!
