I just got my 600 EXRT and I put new batteries into the device and found the same issue. I called around and found a solution that could help you. I powered the device down. Next I held down the two clear buttons under the display and turned the device on. I then move the power switch to lock and the device began working. I believe it reset the system and cleared out the problem.
Hope this helps!

I too have this issue. I bought a new 600ex-rt from thecamerastore (calgary), and no atter what type of batteries I put in (duracel AA, or Energgizer Advanced lithium), I got the dead battery symbol. This is hyper frustrating, I've tried everything so far suggested in the forums. Anyone have any ideas?

i had the same problem, i tried with my Eneloop but got the battery indicator, then tried with some alkaline (duracell) and the same problem, however i left the alkaline batteries in for a few minutes (i think the flash was OFF meanwhile) and after that it worked, seems like the system needed to get some juice into it first.
i havn't had the batteries in all night, and just popped them back in now, and there was no problem/wait, so perhaps it is just a firsttime thing ?
hope this helps, i was ready to replace my unit... i dont get why the manual says nothing about this "issue" .. that was very frustrating.

I had the same problem. First I tried new batteries. No luck. I have two 600EX-RTs so I swapped batteries. The "Bad Batteries" workered in the other unit. The other units' batteries wouldn't work in the unit in question. I tried hitting the reset buttuns with no luck. I had had the new unit for a few month's but haden't used since I first got it. I was ready to return it. But of course I came here first. Holding down the two reset buttuns while turning the unit on is a challenge. Especially when you're ready to throw the thing down. First I tried holding the two buttons down while going from off to on and then lock. No luck. I tried it a few times. Then it tried holding the buttons down while going from off to lock then on. No luck again. Then I tried opening the battery compartement, turning the unit on and then closing the door. No luck again. I gave the first solution again, by holding the two buttons down, going from off to on then lock. Then it worked. This was at 10:00 at night and I was tired and might not have all the sequences exact, but the moral of the story is to try and try again. Hope this helps.

Finally got it running doing the clear screen hold/reset and then turn on method. As you said it took more than one try - in my case seven times. Thanks to nvs397 for pointing out that you have to do it multiple times or I would have been stuck.
Kind of a stupid thing to have to do. Not sure why Canon cannot fix this...
