Twice I've recently bought a new, electronical device and twice the manual insisted on starting it by pressing a button, which does not appear to exist.
On one of the devices there's supposedly an 'on'-button, according to the manual. However, on the physical device there's a '1'-button.
On the other there's an extra button, which you have to operate, but it's not mentioned in the manual. And the drawing of the product does differ from the actual design of the product it was shipped with (but not so much that I suspect it's a mixup of product and manual).
I just wonder: if the producers don't care enough to update this 'manual', which is about 50 words long and has a small drawing, what else don't they care about ?
