Yes your both right, but imagine your car manual telling you your brake pedal is the accelerator- doesn't matter if it's a typo. a mistake or whatever, those instructions are what tells the user how to use whatever he/she has bought and it's the responsibility of the manufacturer to make sure everything he has said is 100% correct- i'm not knocking his engineering, and boy do I know what it's like to make mistakes in engineering! - but I can't forgive instructions been wrong- it's ink- it should be written, read, re-read, checked by at least another 5 people who know what they're talking about and any mistakes corrected and re-write them there is no excuse in my book, sorry.
