Notes on use

• In order to ensure comparable values, always measure your blood pressure at the same time of day.
• Do not take a measurement within 30 minutes of eating, drinking, smoking or exercising.
• Before the initial blood pressure measurement, make sure always to rest for about 5 minutes.
• Furthermore, if you want to take several measurements in succession, make sure always to wait for at least 1 minute between the individual measurements.
• Repeat the measurement if you are unsure of the measured value.
• The measurements taken by you are for your information only – they are no substitute for a medical examination.
• Discuss the measurements with your doctor and never base any medical decisions on them (e.g. medicines and their administration).
• Using the blood pressure monitor outside your home environment or whilst on the move (e.g. whilst travelling in a car, ambulance or helicopter, or whilst undertaking physical activity such as playing sport) can influence the measurement accuracy and cause incorrect measurements.
• Do not use the blood pressure monitor on newborns or patients with preeclampsia. We recommend consulting a doctor before using the blood pressure monitor during pregnancy.
• In the case of restricted circulation on the arm as a result of chronic or acute vascular diseases (including vascular constriction), the accuracy of the wrist measurement is limited. In this case you should avoid using an upper arm blood pressure monitor.
• Cardiovascular diseases may lead to incorrect measurements or have a detrimental effect on measurement accuracy. The same also applies to very low blood pressure, diabetes, circulatory disorders and arrhythmias as well as chills or shaking.
• This device is not intended for use by people (including children) with restricted physical, sensory or mental skills or a lack of experience and/or a lack of knowledge, unless they are supervised by a person who is responsible for their safety or are instructed by such a person in how to use the device.

Measuring blood pressure

Ensure the device is at room temperature before measuring. The measurement can be performed on the left or right wrist.

Attaching the cuff

• Expose your wrist. Ensure that the circulation of the arm is not hindered by tight clothing or similar.
• Place the cuff on the inside of your wrist.
  
• Close the cuff with the hook-and-loop fastener such that the upper edge of the device is positioned approx. 1 cm underneath the heel of the hand.
  
• The cuff must be fitted tightly around the wrist, but must not constrict.
  

Blood pressure may vary between the right and left arm, which may mean that the measured blood pressure values are different. Always perform the measurement on the same arm.

Adopt the correct posture

• Before the initial blood pressure measurement, make sure always to rest for about 5 minutes. Otherwise deviations can occur.
• Furthermore, if you want to take several measurements in succession, make sure always to wait for at least 1 minute between the individual measurements.
• You can take the measurement while sitting or lying. To take your blood pressure, make sure you are sitting comfortably with your arms and back leaning on something. Do not cross your legs. Place your feet flat on the ground. Make sure to rest your arm and move it. Always make sure that the cuff is at heart level. Otherwise significant deviations can occur. Relax your arm and the palm of your hand.
  
• To avoid falsifying the measurement, it is important to remain still during the measurement and not to speak.

Performing the blood pressure measurement

As described above, attach the cuff and adopt the posture in which you want to perform the measurement.

• Press the START/STOP button to start the blood pressure monitor. All displays will illuminate briefly.
  

The blood pressure monitor will begin the measurement automatically after 5 seconds.
The measurement is taken during the inflation phase.

• Press the START/STOP button to switch off the blood pressure monitor. The measurement is then stored in the selected user memory.

If Bluetooth data transfer is activated, data is transferred after pressing the START/STOP button .
The Bluetooth symbol flashes on the display. The blood pressure monitor now attempts to connect to the app for approx. 30 seconds.
The Bluetooth symbol stops flashing as soon as a connection is established. All measurement data is automatically transferred to the app. Once the data has been successfully transferred, the device switches off.

• If a connection to the app cannot be established after 30 seconds, the Bluetooth symbol goes out and the blood pressure monitor switches off automatically after 3 minutes.
• If you forget to turn off the device, it will switch off automatically after a maximum of 3 minutes. In this case too, the value is stored in the selected or most recently used user memory.
• Wait for at least 1 minute before taking another measurement.
  

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 treatment 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 bar chart 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'.
