Pulse Flex 2i won't switch on

I have a brand new pair of Pulse Flex 2i. The software is updated and I'm not using a battery pack. The speakers have been functioning well for 1 day exactly. After unplugging them they stopped working.

The only thing that changed today was adding a Powernode N330. I managed to get everything functioning. But then the app suddenly couldn't find any players. According to the support page i had to perform a network reset, meaning unplugging all devices. After doing so the speakers won't start up. I do see a red light, then a blue light and then nothing. Dead. How do i fix this? Thank you.

PS. After the network reset the Powernode is detected by the app. But if course the speakers aren't since they don't start up properly.

Update: The issue is finally solved. By accident i found the player reset page. After the reset the speakers fired up again. Still wondering: Why no proper manual is provided after buying expensive hardware? The whole support site is quite nerdy (no offense). It's more like Reddit than a support site.
