Have you installed the cabinet of kitchen and turn it on only manuel and from what few works reasonably! Now I wanted to change the batteries, which is still a major disaster, because only the first two batteries can easily be removed and the third battery is not tuned to get in the rear battery compartment, because you can not remove the back part! You have both sides Mühsam Unscrew (each 2 miniscrews) to turn forward to the rear battery or remove the LED light strip thus! Have Fun!
