The manual listed for the 610i is somewhat different - all button "mapping " is in another document.

Mine had the same note as yours David.

The 1st 610i I received was not fully assembled - the rhs plastic endcap or piece was not on the charger when I opened the box. The screws were not in with it either.

I sent it back and had to wait almost another 2 weeks before the replacement showed up. All e RC said they had never seen one like that, partially assembled. My luck....
