Wearing the device
Wear this device on the outside of your arm in a position that does not interfere with your ulna. Secure it to your arm so
that there is no gap between the device and your arm. Also, make it tight enough so that no gaps can occur when
exercising.
Note:
When you are wearing the device in the correct position, HR measuring is enabled after about 30 seconds.

Important:
Measuring may not be possible in the following situations.
❏ When the outside temperature or body temperature are low due to the season or wind
❏ When the pressure is too weak or too strong
❏ When taking medicine to lower your blood pressure
❏ When you have arrhythmia
Try wearing the device on your other arm if there are frequent abnormalities in measuring, or the value
displayed is unusually high when compared to normal measurements.
