The manual does not correspond to the functions of the product and is written incomprehensible. It is of a "set-up button" is mentioned, the it but do not exist on the device. The function to delete pictures (you can use the Set-up button - yippee), for example, the preset glossy panorama of Hama itself not working. I can not choose which ones would have the photos on my USB stick I displayed and which are not - the photo frame just shows all the pictures and included stupidly also photographed invoices or statistics from my job context, of which I could not explain to me how they noticed on the stick. But no problem, I would have to delete from the internal memory again. - Fair enough: but I do not get deleted photos! That's just not for lack of set-up button and the face of buttons, which are in a menu that is not there with me. Measured against the current state of the technology the picture frame, with its lack of functionality and usability far too expensive and frankly scrap.
