Simply wrap the self-contained monitor and cuff around your wrist and press the button! Cuff inflates automatically to the proper pressure; deflates automatically when finished reading seconds later. Your systolic and diastolic blood pressure readings are displayed on the large, easy-to-read, LCD screen, as is your pulse rate, date and time. Memory recall of 99 stored readings. Auto-off. Includes storage case and literature, but not the two AAA batteries.
