My Garmin Index Smart Scale out of the blue and without using it just have on the screen with big letters ERR2.
I did replace the batteries a view monthes ago and was working fine.
The solution mentioned by an other user did not work ("changing batteries, resetting and removing from and re-pairing to Garmin Connect").
Still the same ERR2.
What can I do Garmin Helpcenter! What can I do except bying a new expensive scale?!
