It's concerning if they still haven't fixed that part in the manual. I haven't checked for a while.As an ATC owner thats pretty concerning. If they are that sloppy with a public facing manual what else is going on? Boeing many years ago used the mantra "if there is a coffee ring on someone's desk then it means that our engines don't work". They used this example to drive excellence in everything that they did. I am not saying that Boeing are perfect, it's just an example of a total quality control mindset.
And that they also insist on certain of their packaging to be used to protect speakers whilst at their factory then that's starting to tell a story.
