Is there a way to factory reset 600EX-RT Speedlites?

[jourdak]

Hey folks, 

I've been having continual problems with one of my three 600EX-RT Speedlites. Specifically that no matter what settings I change, it continues to not be correctly synced to the shutter of the camera. I was wondering if there was a way to do a full reset of the flash in a vain attempt that it might help before I send it off to the factory repair system...

Thanks in advance!

Thanks a ton! Appreciate that. Unfortunately, still hasn't solved the issue but thanks for your time and feedback.
