What does the E2 error code mean and how do I fix it?

The E2 error appears when you move or talk during a measurement and the arm cuff does not inflate sufficiently, or when systolic pressure is above 210 mmHg. Remain still and do not talk during measurement. If E2 appears repeatedly, manually inflate the arm cuff until it is 30 to 40 mmHg above your previous systolic reading. (Page 36)
