Hi SofaBaton, thanks for the reply. On the Add/Repair Keys, I click "Power" for repair but the page shown up is only allowed for sorting, and no other option can be found, your suggestion of "filter instructions from cloud data" not appeared. I think this is because I set up this device via bluetooth, so it cannot repair, isn't it?
I also increased the delay time to 3.5, 4 and 5s, but still cannot power on, only can power off.
I want to send you a picture, but how can I attach the pic to you in this post?
