Hi all.. I have a couple of questions regarding the use of the Inon Z240's with the Nauticam / OM-D EM-5
1) "advance cancel circuit switch". Should that be in the up or down position when using optical fibre connection?
2) what is the purpose of the +1/4 EV compensation switch on the front?
I've learnt one thing…. "there is never a dumb question… it only becomes dumb when you don't ask…"
Thanks for your patience - Karen

My understanding - which is contrary to what "barilhu" says - is:
When you shoot "STTL" with your Inon, you will need to have the button in the "Up/Out" position, when you shoot manual, you need to push it in.
("If your camera does not fire a pre-flash, ACC must be disabled.") - when you shoot "Inon manual", you will set your internal OM-D strobe to "manual" and 1/64 power (which saves camera battery power and is enough to trigger the Inon), and no preflash is emitted.
The switch in the front is for use with "Auto" - which you normally do NOT use with you rOM-D, so forget it. (The strobe and not the camera will measure the amount of light that is reflected from the subject and will shut off when enough light has arrived. The plus 1/4 switch will cut down the amount of light that reaches the strobe sensor, so the strobe burns longer)
