Irregular Pulse Function
If the pulse rate varies by more than ±25 % from the average while a measurement is being taken, when measurement is completed the 
mark will be displayed.
•The 
mark will lit after approximately 6 seconds of blinking when the measurement is completed.
•If the 
mark is lit, please take the measurement again.
•In some cases, if the pulse rate fluctuates greatly while a measurement is being taken, it may be impossible to obtain an accurate reading.
•If you save a reading where an irregular pulse was recorded, the 
mark will be displayed when you recall that reading.
Even if the 
mark is displayed, this doesn’t mean whether or not the pulse is, in fact, irregular.
*This function is designed to act as a guide to help you to obtain accurate readings (please see page 14).
Even if the 
mark is not displayed, we recommend that you take measurements
*If the 
mark is frequently displayed, please consult a health professional for your health condition.
Don’t try to interpret readings or attempt to treat any condition yourself.
Always follow the guidance of a health professional.
