Using Call Features - Samsung SM-R150 User Manual

Using the earbuds
• B ecause the heart rate sensor uses light to approximate heart rate, its accuracy may
vary due to physical factors that affect light absorption and reflection, such as blood
circulation/blood pressure, skin condition and location and concentration of blood
vessels.
• I f obstructions between the heart rate sensor and your ear, such as body hair, dirt, or
other objects, prevent the light from reflecting evenly, measurements may be inaccurate.
• T he accuracy of the heart rate sensor may be diminished when you are trying to measure
infants' heart rates.
• I f the heart rate sensor is dirty, clean it before use.
• I f the heart rate sensor is damaged, measurements may be inaccurate.
• I f your earbuds become hot to the touch, stop measuring and remove them from your
ears. Extended exposure of skin to hot earbuds can result in burns.
