For those who have had mastectomy surgery (especially
whose' lymph nodes removed), it's recommend take a
measurement on the unaffected side.
When used among medical electronic equipments on the
same limb, pressurization of the cuff may cause temporarily
malfunction to other devices.

1. Do not use the device on infants, children, or those who
cannot express their own intention.
2. The device is equipped with sensitive electronic components.
While measuring, avoid strong electrical or electromagnetic
fields, e.g. mobile phones, microwave ovens, etc; or it may
lead to temporary reading error or inaccuracy.
3. Consider the electromagnetic compatibility of the device (ex.
power disturbance, radio frequency interference etc.) Please
use it indoor only.
4. Over high frequency measurements may result in blood
flow interference, which is likely to cause uncomfortable
sensations, such as partial subcutaneous hemorrhage,
or temporary numbness to your wrist. In general, these
symptoms should not last long. However, if you do not
recover in time, please seek your medical practitioners for
help.
