PX3 red LED flashing?

Just built my PX3 and it works nicely, however I have a quick question - I can see a red LED flashing inside, have searched for any mention of this, is this normal?

Re: PX3 red LED flashing?

Mine does this as well, if there's a way to disable it that would be neat.
I'm not sure if it's tied to some function that can be disabled or not, but
it stands out a bit when you're operating in the dark. Not a big deal by
any means, it's only really noticeable to me when my eyes are dark-adapted.

There is one in the KX3 as well. It is normal. Think of it as a heartbeat.

What does the red flashing LED inside the PX3 mean? It's a troubleshooting tool. There are actually two of them (one underneath the power supply board). One is controlled directly by the microprocessor, so if it is blinking the CPU is OK. The other is driven by the graphics processor, so it is blinking then that chip is OK also. Thanks to Alan NA1L in email to the Yahoo KX3 group 10/8/2014.

Cheers and 73,

Re: PX3 red LED flashing?

Thanks everyone for putting my mind at rest. I was worried that red meant something bad, normally I think of a green light as good. Can we have a firmware update update to fix this? ;-)
