Ensure the device is at room temperature before measuring.

Attaching the cuff

• Place the cuff on to the bare left upper arm. The circulation of the arm must not be hindered by tight clothing or similar.
• The cuff must be placed on the upper arm so that the bottom edge is positioned 2 – 3 cm above the elbow and over the artery. The line should point to the center of the palm.
• Now tighten the free end of the cuff, but make sure that it is not too tight around the arm and close the hook-and-loop fastener. The cuff should be fastened so that two fingers can fit under the cuff.
• Now insert the cuff line into the connection for the cuff connector.
  Important : The unit may only be operated with the original cuff. The cuff is suitable for an arm circumference of 22 to 42 cm.

Adopting the correct posture

• Before every measurement, relax for about five minutes. Otherwise, deviations can occur.
• You can take the measurement while sitting or lying. Always make sure that the cuff is at heart level.
• To carry out a blood pressure measurement, 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.
• 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.

• Start the blood pressure monitor with the START/STOP button. After the full-screen display, the respective alarm symbols are displayed if alarm 1 / 2 is activated.

• The cuff automatically inflates. The cuff’s air pressure is slowly released. If you already recognize a tendency for high blood pressure, you should reinflate the cuff and increase the cuff’s pressure again. As soon as a pulse is found, the pulse symbol will be displayed.

• The cuff position control symbol is displayed throughout the entire measurement. If the cuff is applied too tightly or too loosely, then and “Er3 ” are displayed.

• To switch off, press the START/STOP button. If you forget to turn off the device, it will switch itself off automatically after approx. 3 minutes.

Wait at least 5 minutes 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 heartbeats, pulse being slow or too fast) can be caused by factors such as heart disease, age, physical makeup, 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.

Classification of measurements

• The measurements can be classified and evaluated by 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 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
