Usage of the word "technically"

[EndlessHope]

He lives in America, speaks American, but technically, he isn't American.

Don't be technical, you'll get tired.

I came across this word many times, and it gives a sense of "accurate,accurately" when doing something, is that right?
Thanks

Hi Milanya,
thanks for the clarification, sometimes, I do understand the meaning of the word but I'm not so confident to use it.
