and other vital signs correctly?

1 For better accuracy, do keep your arm still, fasten the strap

tightly, and make sure the screen is facing up. Please make

sure the watch is worn on the correct position of the wrist,

which is at least one-index-finger-width away from the carpal

bone.

2 If you are not wearing your band, or wearing it incorrectly,

an error message will be displayed. Please read the onscreen

instructions for how to wear it correctly and touch Retry to

restart the measurement.
