I know the hot end of a soldering iron but I wanted to know was what kind of battery is it. Or is it an akku? And why is it there? I have 3 spare-boards and the batteries have: 2.2Volt; 0.22Volt and 0.20Volt. Do they buffer the presets? or the parameters?
If I set new presets they will work until the camera is restartet. Then the older presets are activ, the new once forgotten. Any ideas?
Great. Exactly it is the same model. A Lithium Battery. OK now: what is this battery for? could that be a backup batterie for all parameters? And why do they have only 0,22 V. I will try to find this battery and replace it.
