Heart Rate Measurement
Precautions
Heart Rate Measurement Functions
●
The back cover of the watch has a built-in
sensor that
detects your pulse. This is used
to calculate and display an approximate
heart rate value. The factors below can
cause error in the displayed heart rate
value.
ー
How the watch is affixed to the wrist
ー
Individual wrist characteristics and
condition
ー
Training type and/or intensity
ー
Sweat, dirt, and/or other foreign matter
around the sensor
All of this means that heart rate values
displayed by the watch are approximate, and
no guarantees are made concerning their
accuracy.
●
The
heart
rate measurement function of this
watch is intended for recreational purposes,
and should not be used in any way for
medical purposes.
●
Heart rate measurement is automatically
disabled when the battery level indicator
shows
or lower.
●
The heart rate sensor may not be able to
take measurements if your wrist is cold
because you are exercising in a cold
location or for some other reason.
Wrist Heart Rate Measurement Sleep
(Power Saving)
The heart rate sensor measures your heart
rate
at
intervals if the watch is not moved for a
certain amount of time.
If heart rate measurement does not start when
you strap
the watch onto your wrist, it will start
when you move your wrist.
Blood Oxygen Level
Measurement
Your watch can measure your blood oxygen
level.
A normal blood oxygen level is said to be 95%
to 100%, but this varies depending on your
activity level and physical condition.
Note
●
Note that values displayed by this
watch are for reference only. Should
you feel any abnormalities, consult
with your doctor immediately.
Important!
●
Before starting a blood oxygen level
operation, be
sure to affix this watch to
your wrist. Starting a measurement
operation and then affixing the watch
to your wrist may make correct
measurement impossible.
●
The blood oxygen level measurement
function is not intended as a medical
device for diagnosing specific
diseases. It is intended for general
health maintenance only.
Measuring Your Blood
Oxygen Level
Important!
●
It may not be possible to obtain blood
oxygen level measurement results if
you are
in a cold location and your wrist
is cold. Warm your wrist before
attempting measurement.
●
If measurement at the same location
on your wrist fails continuously or if
measured values fluctuate widely,
change the location on your wrist
where you are wearing the watch. You
can also try moving the watch to your
opposite wrist for measurement.
●
Take several measurements under
identical conditions, moving the watch
around your wrist. Find the wrist
location where measurement is most
stable.
●
Do not take measurements
immediately after exercising. Wait until
your breathing stabilizes.
●
During measurement, keep your arm
still and do not move it.
●
During measurement, refrain from
talking and do not hold your breath.
1. While
seated, place your arm on a table or
some other flat surface.
2. Keep
your elbow and wrist as unbent and
straight as possible.
