Below the sticker we have two Philips screws (red). Unscrew them.
I don't really know how the yellow part is supposed to open. I poked around a little with the slot screwdriver and ended up breaking the pin. I does not really matter as the screws make the construction secure enough.
Now carefully pry apart the two halves of the cover, starting from the side of the battery compartment.
