[Accessories] Main unit USB terminal Instruction manual Cosmetic box [Product Description] vívosmart® HR J is a lifelog that is equipped with an optical heart rate monitor that allows you to easily measure your heart rate anytime, just by wearing it on your wrist. Because the built-in optical heart rate monitor on the back of the main unit measures your pulse at your wrist, there is no need to wear a chest strap heart rate monitor. In addition to the move bar, sleep mode, and smartphone link*, new features have been added, such as a convenient heart rate data transfer function and the ability to see how many times you've climbed stairs in a day and how much you've exercised in a week. With simple operation using one button and a light touch on the display, it continuously tracks your lifestyle 24 hours a day, from waking up to commuting, from showering to going to bed. By simply uploading the recorded data to "Garmin Connect," a free internet site provided by Garmin, data such as steps/distance/floors climbed/weekly exercise volume/calories/heart rate/time/date are automatically analyzed and displayed in graphs. In addition, you can enjoy sleep data and data sharing with other users.
