The wrist blood pressure monitor is used for non-invasive measurement and monitoring of adults' arterial blood pressure.
This allows you to quickly and easily measure your blood pressure and to display the last recorded measurement. A warning is issued for anyone suffering from cardiac arrhythmia.
The recorded values are classified and evaluated graphically.

Important information

Signs and symbols

The following symbols are used in these instructions for use, on the packaging and on the type plate for the device and accessories:

Advice 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 after 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 not a 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.
• 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. Supervise children around the device to ensure they do not play with it.
• 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.
• The blood pressure monitor must not be used in connection with a high-frequency surgical unit.
• Only use the unit on people who have the specified wrist measurement for the device.
• Please note that when inflating, the functions of the limb in question may be impaired.
• During the blood pressure measurement, blood circulation must not be stopped for an unnecessarily long time. If the device malfunctions, remove the cuff from the arm.
• Do not allow sustained pressure in the cuff or frequent measurements. The resulting restriction of the blood flow may cause injury.
• Ensure that the cuff is not placed on an arm in which the arteries or veins are undergoing medical treatment, e.g. intravascular access or therapy, or an arteriovenous (AV) shunt.
• Do not use the cuff on people who have undergone a mastectomy.
• Do not place the cuff over wounds as this may cause further injury.
• The blood pressure monitor can only be operated with batteries.
• To conserve the batteries, the monitor switches off automatically if no buttons are pressed for one minute.

Inserting battery

• Remove the battery compartment lid on the lower left side of the device.
  
• Insert two 1.5 V micro batteries (alkaline, type LR03).
• Make sure that the batteries are inserted with the correct polarity, according to the label on the battery compartment lid. Do not use rechargeable batteries.
  
• Replace the battery cover carefully.

If the battery change is continuously illuminated, measurement is no longer possible and you must replace all the batteries.

Measuring blood pressure

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

Positioning 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.
  
• Fasten the cuff with the hook and loop fastener so that the upper edge of the monitor is positioned approx. 1 cm below the ball of your thumb.
  
• The cuff has to be fitted tightly around the wrist but should not constrict it.
  

Important: The instrument should only be operated with the original cuff.
Blood pressure may vary between the right and left wrist, which may mean that the measured blood pressure values are different. Always perform the measurement on the same wrist.
If the values between the two wrists are significantly different, please consult your doctor to determine which wrist should be used for the measurement.

Correct posture

• Before the initial blood pressure measurement, make sure always to rest for about 5 minutes. Otherwise there may be divergences.
• 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 perform the measurement either sitting or lying down. 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. It is essential to support your arm and have it at an angle. Always make sure that the cuff is level with your heart. Otherwise there may be serious divergences. Relax your arm and the palms of your hands.
  
• In order not to distort the result, it is important to keep still during the measurement and not talk.

Measuring blood pressure

• Start the blood pressure monitor with the start/stop button . A beep and a brief display of all the symbols confirm that the device is switched on.
• Before the measurement, the last saved test result is briefly displayed. If there is no measurement in the memory, the instrument always displays the value .
• The cuff automatically inflates. Cuff air pressure is released slowly.
• If a tendency towards high blood pressure is already detectable, the cuff is pumped up again and cuff pressure increased further. The pulse symbol flashes as soon as a pulse is found.
• After the pressure has been completely reduced, the systolic pressure, diastolic pressure and pulse readings are displayed.
• Measuring can be cancelled at any time by pressing the start/stop button .
• appears if it has not been possible to perform the measurement properly. Observe the section in these instructions on error messages/troubleshooting and repeat the measurement.
• The test result is saved automatically.

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 the flashing icon .
This may be an indicator for arrhythmia. Arrhythmia is a condition where the heart rhythm is abnormal as a result of defects in the bioelectrical system controlling the heart beat. The symptoms (omitted or premature heart beats, 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 ascertained through examination by your doctor.
Repeat the measurement if the flashing icon 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 icon 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 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'.

Error messages/troubleshooting

In case of faults, the message appears in the display.

• Error messages may appear if:
• systolic or diastolic pressure could not be measured ( or appears on the display)
• systolic or diastolic pressure was outside the measurement range (" " or " " appears on the display)
• the cuff is fastened too tightly or loosely ( or appears on the display)
• the pump pressure is higher than 300 mmHg ( appears on the display)
• pumping up takes longer than 160 seconds ( appears on the display)
• there is a system or device error ( or appears on the display)
• the batteries are almost empty .

In such cases, repeat the measurement. Ensure that you do not move or speak during the measurement. If necessary, reinsert or replace the batteries.

Technical alarm – description
Should the recorded blood pressure (systolic or diastolic) lie outside the limits specified in the section "Technical specifications", the technical alarm will appear on the display indicating either "Hi" or "Lo". In such cases, you should seek medical assistance and check the accuracy of your procedure.
The limit values for the technical alarm are factory set and cannot be adjusted or deactivated. These alarm limit values are accorded second priority under the standard IEC 60601-1-8.
The technical alarm is a non-locking alarm and must not be reset. The signal shown on the display will disappear automatically after about 8 seconds.
