A : Every time I use this home blood pressure monitor, I get a different reading. I think I'm doing it wrong. Can you show me how to use it correctly?

B : Yes, of course. First, you have to put the strap around your arm.

A : Like this? Am I doing this correctly?

B : That looks a little too tight.

A : Oh, how about now?

B : Now it looks a bit too loose. If it's too tight or too loose, you'll get an incorrect reading.

A : __________________________________

B : Press the button now. You shouldn't move or speak.
