ok i asked the question wrong ....?

When they buzz you it automatically puts the word buzz. Your sound must be off or you have some setting that does not allow you to hear it.

yep, means they want your attention.

And are trying to get it the polite way without pushing that button and blowing your ears out and your butt out of the chair.

yea its means that they want to talk to u r they just want ur attention.
