Usage

General rules when measuring blood pressure yourself

• In order to generate as informative a profile of the progression of your blood pressure as possible and ensure that the measured values can be compared, measure your blood pressure regularly and always at the same times of day.
• It is recommended that you measure your blood pressure twice a day: once in the morning after getting up and once in the evening.
• Always carry out the measurement when you are sufficiently physically rested.
• Avoid taking measurements during stressful periods.
• Do not measure within 30 minutes of eating, drinking, smoking, or exercising.
• Before the initial blood pressure measurement, rest for 5 minutes.
• If you want to take several measurements in succession, wait at least 1 minute between individual measurements.
• Repeat the measurement if you are unsure of the measured value.

Attaching the cuff

• Fundamentally, blood pressure can be measured on both arms.
• Certain deviations between the measured blood pressure on the right arm and left arm are due to physiological causes and are completely normal.
• Always measure the arm with the highest blood pressure values.
• Before starting self-measurement, consult your doctor in this regard.
• From this point on, always take measurements on the same arm.
• The device may only be operated with one of the specified cuffs.
• Select the cuff according to your upper arm circumference.
• Check the cuff fit before measurement using the index mark described below.

Included in standard delivery

• Pass your bare upper arm through the tube-shaped cuff. The circulation of the arm must not be hindered by tight clothing or similar.
• Place the device on the upper arm so that the bottom edge is positioned approx. 2–3 cm above the elbow.
• Adjust the device so that the “ARTERY” mark is directly over the artery.
• Press the easyLock locking button until it clicks into place to activate the locking mechanism.
• After it has clicked into place, adjust the cuff precisely by turning the easyLock locking button.
• The cuff should be fastened securely but not too tightly, so that two fingers fit under the closed cuff.
• The easyLock cuff is suitable if parts of the index marking are still visible after attaching and adjusting the cuff and do not disappear into the cuff.

Cuff tightness indicator
The device has a cuff tightness indicator function. Using this feature, the device automatically checks the correct positioning of the cuff on your upper arm during measurement. If the cuff is correctly positioned, the symbol OK will appear on the display during inflation. It will remain there until the measurement has been successfully completed and will then be displayed together with the determined measured values. In the event that the cuff has been positioned incorrectly, the measurement is cancelled and an error message appears in the display. In this case, please observe the information in the section “What if there are problems?”.

Adopting the correct posture

Correct Sitting Position

• Sit upright and comfortably for the blood pressure measurement.
• Lean back and place your arm on a surface.

To transfer the measured values, proceed as follows:

Evaluating the results

General information about blood pressure

• Blood pressure is the force with which the bloodstream presses against the arterial walls. Arterial blood pressure constantly changes during a cardiac cycle.
• Blood pressure is always stated in the form of two values:
  • The highest pressure in the cycle is called systolic blood pressure. This occurs when the heart muscle contracts and blood is pumped into the blood vessels.
  • The lowest pressure is called diastolic blood pressure. This occurs when the heart muscle has completely relaxed and the heart fills with blood.
• Fluctuations in blood pressure are normal.
• Even during repeated measurements, considerable differences between measured values may occur.
• One-off or irregular measurements do not provide reliable information about actual blood pressure.
• Reliable assessment is only possible when measurements are performed regularly under comparable conditions.

Cardiac arrhythmia

This device can identify any cardiac rhythm disturbances as part of the analysis of your recorded pulse signal during blood pressure measurement. In this case, after the measurement, the device will indicate any irregularities in your pulse by displaying the symbol in the display. 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 disposition, excess alcohol and tobacco, stress, or lack of sleep. If the symbol appears on the display after the measurement, the measurement must be repeated as the measurement accuracy may be impaired. To assess your blood pressure, only use the results that have been recorded without corresponding irregularities in your pulse. If the symbol appears frequently, please consult your doctor. Only they can establish the existence of an arrhythmia during a checkup, using their means of diagnosis.

LED risk indicator

The World Health Organization (WHO) has defined the internationally recognised classification for the evaluation of measured blood pressure values listed in the table below: 

The LED risk indicator (coloured LED on the device to the left of the display) shows which category the recorded blood pressure falls into. If the measured values are in two different classifications (e.g. systole in the high normal category and diastole in the normal category), the risk indicator then always shows you the higher category – “high normal” in the example described. Please be aware that these standard values can only serve as a general guideline, as the individual blood pressure varies in different people and different age groups, etc. Furthermore, it must be noted that measurements taken yourself while at home are generally lower than those that are taken by the doctor. For this reason, you must regularly consult your doctor for advice. Only they can give you your personal target values for controlled blood pressure – in particular if you receive medicinal therapy.

Troubleshooting — Common problems, fixes and preventive steps

• No display/unit won’t turn on: Check and replace the 4 × AAA batteries and ensure batteries are inserted with correct polarity; try fresh batteries and clean battery contacts if necessary.
• Poor or inconsistent readings: Ensure the cuff is placed on a bare upper arm, follow the position check indicator, sit quietly for 5 minutes before measurement and keep arm at heart level; retake reading after 1–2 minutes if result seems abnormal.
• “Err” or error codes during measurement: Common errors are caused by movement, talking, incorrect cuff position or irregular pulse — remain still, re-fit the cuff, and retry; consult the manual’s error table for device-specific codes and suggested actions.
• Bluetooth pairing failures: Ensure Bluetooth is enabled on your phone, open the Beurer HealthManager Pro app and follow pairing instructions; remove prior pairings, restart phone and device, and update app/firmware if available.
• Arrhythmia detection warnings: The device flags possible irregular heartbeats but is not a diagnostic ECG — contact a healthcare professional for follow-up if arrhythmia is repeatedly detected.

Preventive measures: Store the device in a dry, room-temperature location, avoid exposing it to direct sunlight or humidity, replace batteries before long trips, and periodically clean the cuff with a damp cloth.

Warranty & support: Beurer typically provides a manufacturer warranty (check regional warranty length at purchase; some listings note up to 5 years via certain retailers) and customer support through Beurer’s official channels and authorised dealers.
