Braun shaver 8595

Question

braun shaver 8595

I press the Info key. Does not work. I have charged the shaver for at least two hours.

No display. Booklet says that when there is No display--shave is completely discharged.

Shaver works OK. After shaving, I noticed that the Demo tried to work but it kept moving. Then I noticed that I could not find out anything about the duration of the last shave, the number of shaves and so on.
