Re: Speedlite 600ex-rt battery problem

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!

Hey guys,

 

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?

Re: Speedlite 600ex-rt battery problem

I can confirm the above method of the reset with the clear screen hold, turn to on and then to hold.  

 

It didn't work the first time, it took me 5-6 tries to do it.

Re: Speedlite 600ex-rt battery problem

Hi there,

 

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.

 

Regards

Simon

Re: Speedlite 600ex-rt battery problem

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.

Re: Speedlite 600ex-rt battery problem

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...
