PicoPixPocket projector

There was no user manual in the package of my Philips Picopix 1430

I see the PDF file of the user manual but when I try to open the file with my Philips Picopix 1430, I get the error message "No data found"

Can I play power point files from the internal memory of my Philips PicoPix 1430/1230

Which reference of VGA cable do i need for my Philips PicoPix 1430/1230

How can I explore the content of the USB key I plug to the Philips PicoPix 1430?
