Thanks for answering = do you mean the horizontal slider on the back of the flash - if so I have done that! When it is on the camera and I slide it and half press the shutter it shows change on flash but when it is off camera and in wireless mode and the slider is moved to trailing flash nothing appears to happen. I assume this would not happen until the camera flash strobed to send message to slave 540, but no perceptual change in picture.
I am guessing you have a 360 or 540 and are able to do this - any further help - thoughts would be appreciated.
