(The Reset Button wording was in reply to another question.)
My model is AVM70. It was also mentioned that if I were to cut the yellow wire it would keep the camera one all the time as well. Oh, I did go to Axxera and based upon the model # yo have to download their firmware. I'm not to comfortable in doing that, not computer literate and warns of disabling the whole operation..
