• Replace the battery cover carefully.

If four warning tones sound and the battery replacement symbol appears simultaneously on the display, it is no longer possible to perform a measurement, and all batteries must be replaced. Once the batteries have been removed from the device, the date and time must be set again. Any saved measurements are retained.

Battery Disposal

• Empty, completely flat batteries must be disposed of through specially designated collection boxes, recycling points, or electronics retailers. You are legally required to dispose of batteries.
• The following codes are printed on batteries containing harmful substances:
  • Pb = Battery contains lead.
  • Cd = Battery contains cadmium.
  • Hg = Battery contains mercury.

• Set the month, day, hour, and minute, and confirm each setting with the SET button.

When making settings, you can use the START/STOP button at any time to switch the device off. The settings that have already been performed will be retained.

Operation with the Mains Part

You can also operate this device with a mains part (not included in delivery). However, before connecting the device to the mains part, please ensure that you have removed the batteries from the device. During mains operation, there must not be any batteries in the battery compartment, as this could damage the device. The mains part can be obtained from specialist retailers or from the service address using order number 071.95.

• To prevent possible damage to the device, the blood pressure monitor must only be used with the mains part described here.
• Furthermore, the mains part must only be connected to the mains voltage specified on the type plate.
• Then insert the mains plug of the mains part into the mains socket.
• After using the blood pressure monitor, unplug the mains part from the mains socket first and then disconnect it from the blood pressure monitor. As soon as you unplug the mains part, the blood pressure monitor loses the date and time setting, but the saved measured values are retained.

Measuring Blood Pressure

Please ensure the device is at room temperature before measuring. The measurement can be performed on the left or right arm.

Positioning Cuff

Fit the cuff around your bare upper arm. Blood circulation in the arm should not be restricted by tight clothing or other objects. The cuff should be placed on the upper arm so that the lower edge is 2 to 3 cm above the bend of the elbow and above the artery. The tube should be in line with the centre of the palm. Now place the free end of the cuff snugly, but not too tightly, around the arm, and secure it with the Velcro fastener. 

The cuff should be fitted tightly enough to allow just two fingers to fit beneath it. Insert the cuff tubing into the socket for the cuff attachment. This cuff is suitable for you if the index mark is within the OK range after fitting the cuff on the upper arm. If the measurement is performed on the right upper arm, the tube should be located on the inside of your elbow. Ensure that your arm is not pressing on the tube. Blood pressure may vary between the right and left arm, which may mean that the measured blood pressure values are different. Always measure the same arm. If the values between the two arms are significantly different, please consult your doctor to determine which arm should be used for the measurement. 

Important: The instrument should only be operated with the original cuff. The cuff is suitable for an arm circumference of 22 to 35 cm. A larger cuff for upper arm circumferences from 30 to 42 cm is available from retailers or the service address under order number 162.973.

Adopting the Correct Posture

• Before the initial blood pressure measurement, make sure to rest for about 5 minutes. Otherwise, there may be deviations in the readings.
• You can perform the measurement either sitting or lying down. Always make sure that the cuff is at the same level as your heart.
• To carry out a blood pressure measurement, make sure you are sitting comfortably with your arms and back supported. Do not cross your legs. Place your feet flat on the ground.
• In order not to distort the result, it is important to keep still during the measurement and not talk.

Performing the Blood Pressure Measurement

Measurement

• As described above, attach the cuff and adopt the posture in which you want to perform the measurement.
• Start the device with the START/STOP button. Following the display check, during which all numbers light up, the cuff inflates automatically.
• The cuff is inflated to 190 mmHg. The cuff's air pressure is slowly released. If further inflation is necessary, the monitor increases the cuff pressure automatically. As soon as a pulse is detected, the pulse symbol flashes.

Measuring can be cancelled at any time by pressing the START/STOP button

• Systolic pressure, diastolic pressure, and pulse readings are displayed.
• An error symbol appears if the measurement has not been performed properly. Observe the chapter on error messages/troubleshooting in these instructions for use and repeat the measurement.
• The measurement is automatically stored.
• The device switches off automatically after 3 minutes.

Wait for at least 1 minute before taking another measurement.

Evaluating Results

Cardiac Arrhythmia

This instrument can identify possible cardiac arrhythmia disorders during measurement and, if necessary, indicates the measurement with a flashing cardiac arrhythmia symbol. This may be an indicator of arrhythmia. Arrhythmia is a condition in which the heart rhythm is abnormal as a result of defects in the bioelectrical system controlling the heartbeat. The symptoms (omitted or premature heartbeats, slow or excessively fast heart rate) may be caused, among other things, by heart disease, age, physical predisposition, excessive use of stimulants, stress, or lack of sleep. Arrhythmia can only be diagnosed through examination by your doctor. Repeat the measurement if the flashing cardiac arrhythmia symbol is displayed after the measurement. Please note that you should rest for 5 minutes between measurements and not talk or move during the measurement. If the symbol appears often, please contact your doctor. Any self-diagnosis and treatment based on the test results may be dangerous. It is vital to follow your doctor's instructions.

Risk Indicator

The measurements can be classified and evaluated in accordance with the blood pressure classification table. However, these standard values serve only as a general guideline, as individual blood pressure varies between people and different age groups. 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 graph on the display and the scale on the unit indicate the range of the recorded blood pressure. If the values for systolic and diastolic pressure are in two different ranges (e.g., systolic in the high-normal range and diastolic pressure in the normal range), the graphic classification on the unit indicates the higher range (high-normal in the example described).

Cleaning and Storing the Device and Cuff

• Clean the device and cuff carefully using a slightly damp cloth only.
• Do not use any cleaning agents or solvents.
• Under no circumstances should you hold the device and cuff under water, as this can cause liquid to enter and damage the device and cuff.
• When storing the device and cuff, do not place heavy objects on them. Remove the batteries. The cuff tube should not be bent sharply.

Troubleshooting the Beurer Blood Pressure Monitor BM 40: Common Issues and Fixes

Encountering problems with your Beurer Blood Pressure Monitor BM 40? Start with basic checks: Ensure the cuff is correctly positioned 2-3 cm above the elbow, the arm is at heart level, and not moving during measurement. Replace batteries if the display is dim or shows a low battery symbol.

• Error signals or application errors: The device signals if cuff pressure is too low/high or the pulse is irregular—reposition the cuff snugly without gaps and relax for 5 minutes before retrying.
• Arrhythmia warning: Displays if heart rhythm disturbance is detected; consult a doctor, but continue monitoring as it doesn't halt measurement.
• No readings or inaccurate values: Verify upper arm circumference fits 22-35 cm cuff; upgrade to XL if needed (Art. No. 162.973). Avoid caffeine/exercise 30 minutes prior for preventive accuracy.
• Memory or average not displaying: Automatic switch-off after 5 minutes—power on and select user mode.

Prevent issues by storing in the included pouch, avoiding extreme temperatures, and documenting values in the provided record. Beurer offers a 5-year warranty; contact Beurer GmbH, Söflinger Straße 218, 89077 Ulm, Germany, or visit beurer.com support for FAQs and replacements.
