Remove the protective plastic from the heart rate measurement sensor before
taking measurements.
•
Heart rate measuring is intended for human use only. The heart rate may not be
recognized due to surrounding conditions. In this case, the measured heart rate may
not be valid.
•
Take heart rate measurements when you are seated and relaxed.
•
If heart rate measurements are taken at low temperatures, the result may be
inaccurate.
•
Do not move your body while taking heart rate measurements. Doing so may cause
your heart rate to be recorded inaccurately.
•
Users with thin wrists may receive inaccurate heart rate measurements. Inaccurate
measurements occur when the device is loose and the light used to provide the
measurement is reflected unevenly.
•
If the measurement is very different from the expected heart rate, rest for 30 minutes
and then measure it again.
•
Measurements are calculated using average values and should be repeated at least
five times.
•
During winter or in cold weather, keep yourself warm when measuring your heart
rate.
•
Smoking or consuming alcohol before taking measurements may cause your heart
rate to be different from your normal heart rate.
•
Do not talk, yawn, or breathe deeply while taking heart rate measurements. Doing
so may cause your heart rate to be recorded inaccurately.
•
If your heart rate is extremely high or low, measurements may be inaccurate.
•
Obstructions between the device’s strap and your wrist, such as body hair or other
objects, may prevent the light reflecting evenly.
•
Heart rate measurements taken for infants and toddlers may be inaccurate.
•
Do not look directly at the heart rate sensor’s lights. Doing so may impair your vision.
•
If heart rate measurements are not working properly, change the position of the
Gear Fit on your wrist.
