If you forget to turn off the device, it will switch off automatically after approx. 3 minutes. In this case too, the value is stored in the selected or most recently used user memory.

Wait at least 5 minutes before taking another measurement.

6. Evaluating results

Cardiac arrhythmia:

This device can identify potential disruptions of the heart rhythm when measuring and if necessary, indicates this after the measurement with the symbol 🤒.

This can be an indicator for arrhythmia. Arrhythmia is an illness in which the heart rhythm is abnormal because of flaws in the bioelectrical system that regulates the heartbeat. The symptoms (skipped or premature heart beats, pulse being slow or too fast) can be caused by factors such as heart disease, age, physical make-up, excess stimulants, stress or lack of sleep. Arrhythmia can only be determined through an examination by your doctor.

If the symbol is shown on the display after the measurement has been taken, repeat the measurement. Please ensure that you rest for 5 minutes beforehand and do not speak or move during the measurement. If the symbol appears frequently, please consult your doctor. Self-diagnosis and treat-

ment based on the measurements can be dangerous. Always follow your GP's instructions.

Risk indicator:

The measurements can be classified and evaluated in accordance with the following table.

However, these standard values serve only as a general guideline, as the individual blood pressure varies in different people and different age groups etc.

It is important to consult your doctor regularly for advice. Your doctor will tell you your individual values for normal blood pressure as well as the value above which your blood pressure is classified as dangerous.

The classification on the display and the scale on the unit show which category the recorded blood pressure values fall into. If the values of systole and diastole fall into two different categories (e.g. systole in the 'High normal' category and diastole in the 'Normal' category), the graphical classification on the device always shows the higher category; for the example given this would be 'High normal'.

Blood pressure value category	Systole (in mmHg)	Diastole (in mmHg)	Action
Setting 3: severe hypertension	≥180≥110		seek medical attention
Setting 2: moderate hypertension	160–1791	00–109	seek medical attention

Blood pressure value category	Systole (in mmHg)	Diastole (in mmHg)	Action
Setting 1: mild hypertension	140–159	90–99	regular monitoring by doctor
High normal 130	13985–89		regular monitoring by doctor
Normal 120–129	80–84 self-monitoring
Optimal <120<80	self-monitoring
