I have 3 600ex-rt speedlites in 3 groups. How do I turn off a group?

1. Master should be in "Radio Master Mode"

2. Use the mode button to toggle to (Gr) group mode.

3. From Group Mode Menu 1, hit the "Gr" group button.

4. Use the dial to navigate the to any group, A through E.

5. Hit the "On/Off" button to toggle any individual group on, or off.

On a 5d mark III.  I want to turn off (and on) Group B or Group C or B and C.  Can I do that other than turning the power off and on at the relevant speedlites?  Can I do it from the camera settings?

Yes, from the flash menu, turn on Radio Transmission, and you can control the group power levels from the camera.

I see I can turn the lites down to 1/128th.  but how about OFF?

Yes, thanks.  It was that "Group" thing used in 2 ways.  Got it and I like it.
