D.1 Blinking

[Subotingoran]

Hello, I just replaced battery on my Gazelle orange (2012)... I bought it with dead battery... Today I was very sad, because it doesn't work, only D.1 blinking on display.. Does anybody knows meaning of that? Please
Sorry about my English...

I don't think one can use any old generic battery with a Gazelle, it has to be a proprietary one, I believe some kind of hand shaking occurs.
