Here are a few tips on how to riff it:
1. One should wash the fingers and the screen previously well cleaned (Logical).
2. You should have a "scotch tape" -Abroller must show (It of course does not have to be the original of Tesa).
3. If now the film of the carrier removed, it may happen that the cut-outs are still on the film. Here then is the first time the "Scotch tape" is used. So you can simply pull off without coming with your fingers.
4. Now set you on the film and paint everything smooth with a plastic card. (Finished ... or is it ???)
5. What if nevertheless a speck of dust has cheated at the display? Since we have again the "Scotch tape". Use a small strip for raising the actually already attached sheet. And hold a second delivery in order to remove the dust in the appropriate place. Just short dranhalten and the dust adhered to the adhesive tape and no longer on the film. (Then again to step 4 and now it's done).
I hope I could help a little with the instructions. :-)
