Hey, I just picked up a Canon 430EZ used plus I bought another Ebay receiver with it. I already own one for my 430EX and it works great, but so far I've only gotten the 430EZ to fire once with it . Has anybody noticed this before or know anything I could possibly be doing wrong? I know the problem isn't with the receiver because I tried the new receiver with my 430EX and it worked. EDIT: Figured the problem out, I have to put it on "M Multi 1HZ" instead of normal M. I guess my question now is what is the "M Multi 1HZ" setting?
