580 off + 430 as slave

Following the instructions in the manual. Options on the 580 are Master-Slave-Off. Tells me in the manual if I want to switch the master off and fire the slave, select off. But what happens is the Master fires and the 430 doesn't?

Are you looking at the switch on the back or the menu settings?

Menu settings, holding Zoom until the display flashes etc....

What you need to do is to press the Zoom button repeatedly until the light ray icon to the left of the flash icon blinks (on the LCD screen). Then use the dial to change the blinking "on" tp "off". This will set the master so that it doesn't flash, only the slaves will. Don't press and hold the Zoom button because that will only let you switch to master mode, slave mode, or wireless mode off.

Here's what the LCD screen should look like when turning off the master flash:

You have to first go into master mode. You do this by first pressing and holding the Zoom button until something flashes on the screen. If it isn't "Master on", turn the dial until "Master on" flashes and then press the Set button in the middle of the dial. Next, press the Zoom button repeatedly until the light ray flashes as I mentioned in my previous post.

Got it Thank you....

I couldn't make that happen but I did go into the camera menu where I was able to disable the master flash and it works perfectly, at least that's the way it is on the MKIII.
