Hello, I successfully set up my new FR 255 previously after that came to me, and after one week I power it off and later I wasn`t able to power it on. I tried to press and hold light button up to 30 seconds -> nothing happend, tried to press light button for one second -> nothing happened, plug watch to USB -> nothing happened. FW version is 10.10
Has anyone else same problem or should I claim to support to my seller ?
