Zenza Bronica S2A, TTL device stuck on speed shutter dial

[Iggy1977]

Hello,
I recently bought a Zenza Bronica S2A with a vintage TTL exposure meter. This exposure meter came in two parts: one part to be mounted as a viewfinder and the other part to be mounted on the shutter speed selection wheel (small 4 claws mount). I wanted to give it a try and mounted it on the camera, but the part on the shutter speed wheel is now unmountable! It is really stuck to it and I fear to break something in the speed selection mechanism if I force too much on it. Do you know about a solution to this problem or do you have any suggestion? I looked for a manual of the exposure meter but didn't find anything.
Thank you
Regards,
Laurent

Pull the outer ring away from the body, and turn whole unit counter clock wise. It is a fair amount of resistance to pull the outter element.
