5. Heart rate measurement
(1) Precaution at the time of measuring heartbeat
* In case that band is moved and band is not adhered to wrist closely
during heartbeat measurement, result of measurement may be
incorrect.
* If moving band to upper thick part after wearing on wrist, more
close adherence is ensured.
* Pay your attention so that heartbeat sensor of band would be
adhered to skin from the time of starting measurement until its
completion.
* In case that there is any unnecessary hindrance between the device
and skin, be sure to measure after removing such hindrance.
* Normally it takes 20 -- 40s for heart rate data to be detected and
displayed
