Reading instructions by a Russian man. A long time ago, my brother bought a screwdriver and was very proud of them (they were just beginning to appear on the market in such a variety). We had to repair the house. I asked for instructions to read what the people were crazy about, saying what to know there: a few buttons, and the hell knows where it lies. He flew to us in a week. It was not possible to turn the screws when the battery went off. The shop refused to repair. They found the workshop and repaired it. A few months later, a bullet came. It turns out, it is not possible to press the beat with much effort. When it flew for the third time (the battery died) and its repair was already paid, the instructions were found. And there, on the broken Russian black and white, all these rules were written.
