HI everybody,

Thanks for the prompt reply. But my problem is not taking the the battery pack out, but how to open the battery door. I am afraid that I already broke the door, but still it does not come off completely. I am planning to eBay it next week. I just wanna make sure it is working.

The door opens just by pressure? I mean just tearing it out up instead of sliding the arrow way? What I can see, it is impossible to slide it towards the arrow, nor backward. The only way is to use a fine knife and take it out by pressure by pulling it up.

Thanks in advance
