BG starts his own business

The battery grip (BG) I bought in the summer of 2012. Actually, a good buy-quality impression and good handling. Unfortunately there was a manual (BA). The use of timing and I've found in Sysiphusarbeit itself. So, since you would have to create a short-BA. Would at least be a nice touch.

But since about three months of BG makes autonomously. When I turn on my EOS 600D, it only takes a few moments until the first photo. The next follow then on foot. After a short break to come even more photos. Is not critical, my 16GB card takes it easily with almost 2,000 images. However, I would decide what I photograph itself. Unfortunately, an attached BG extends a small movement of the camera or a light knocking at BG to produce the undesired images; sometimes even in continuous shooting.

For completeness it should be mentioned that I have operated the camera then without BG. And without undesired series images. Subsequent cross-checking: see above.

For this, I can not assign points.

I'll try to change the BG.
