Should I be concerned?&nbsp; The flash will fire but I am not certain it's firing how it's supposed to. Thank you for any thoughts you can provide!</P><P>Leann</P> Thu, 01 Oct 2020 15:15:52 GMT https://community.usa.canon.com/t5/Speedlite-Flashes/Canon-Speedlite-600EX-II-RT/m-p/320272#M877 ldavis4 2020-10-01T15:15:52Z https://community.usa.canon.com/t5/Speedlite-Flashes/Canon-Speedlite-600EX-II-RT/m-p/320275#M878 <P>Do you mean the&nbsp; flash ready / test flash button? That is what it is supposed to do. Green means charging and ready for quick-flash and Red means fully charged and ready to shoot.</P><P>&nbsp;</P><P><IMG src="https://community.usa.canon.com/t5/image/serverpage/image-id/25294i7B4B928DF4E28356/image-size/original?v=1.0&amp;px=-1" border="0" alt="Untitled.jpg" title="Untitled.jpg" /></P> Thu, 01 Oct 2020 15:36:43 GMT https://community.usa.canon.com/t5/Speedlite-Flashes/Canon-Speedlite-600EX-II-RT/m-p/320275#M878 kvbarkley 2020-10-01T15:36:43Z https://community.usa.canon.com/t5/Speedlite-Flashes/Canon-Speedlite-600EX-II-RT/m-p/320370#M879 <P>awesome, thank you!</P> Fri, 02 Oct 2020 19:51:31 GMT https://community.usa.canon.com/t5/Speedlite-Flashes/Canon-Speedlite-600EX-II-RT/m-p/320370#M879 ldavis4 2020-10-02T19:51:31Z
