Since my other thread on the lighting forum was thread-jacked I thought I would have better luck in here

I was checking out the Nissin I40 Manual and it tells me I should rotate the dial to RMT to use it in wireless remote mode with Sony cameras, but even though I can see the RMT option on the dial it WON'T rotate until RMT. It only goes as far as TTL2. This happens with BOTH my Nissin I40 units

I set the A77II's flash option to Wireless and tried it out with ALL options on the Nissin and I was not able to trigger it remotely. I thought it could have something to do with the camera being on airplane mode but I've tried both ways and could not get it to work.

Am I doing something wrong?
