Can someone explain "Setup: 0%>7.5%"
 

In the "Manual Set" in the PD-170 it has "Setup: 0%>7.5%". I'm assuming that relates to IRE. What should I be using? And why?

Hi Glenn,

You may click on the following link which will bring you to a JVC product page. In that page, look for "Dirty little secret" flash clip that will explain black setup:

Glen, also check out Adam Wilts site. He explains set-up and the pitfalls pretty well.
