9. ASSESSING HIGH BLOOD PRESSURE FOR ADULTS
The following guidelines for assessing high blood pressure (without regard to age or gender) have been
established by the World Health Organization (WHO). Please note that other factors (e.g. diabetes, obesity,
smoking, etc.) need to be taken into consideration. Consult with your physician for accurate assessment, and
never change your treatment by yourself.

10. TECHNICAL ALARM DESCRIPTION
The monitor will show ‘HI’ or ‘Lo’ as technical alarm on LCD with no delay if the determined blood pressure
(systolic or diastolic) is outside the rated range specified in part SPECIFICATIONS. In this case, you should
consult a physician or check if your operation violated the instructions.
The technical alarm condition (outside the rated range) is preset in the factory and cannot be adjusted or
inactivated. This alarm condition is assigned as low priority according to IEC 60601-1-8.
The technical alarm is non-latching and need no reset. The signal displayed on LCD will disappear
automatically after about 8 seconds.
