I pushed in the 'wide panel' and that took care of the problem.&nbsp; The speedlite is working very well. I should have read the trobleshooting section of the manual and I would have discovered that the problem is discussed there as well.....Thanks.</P><P>&nbsp;</P> Sun, 11 Oct 2015 14:03:24 GMT https://community.usa.canon.com/t5/Speedlite-Flashes/Speedlite-580EX/m-p/153727#M2685 jmaniscalco 2015-10-11T14:03:24Z
