Getting to know your instrument
The wrist blood pressure monitor is used for non-invasive measurement and monitoring of adults’ arterial blood pressure. You can use it to measure your blood pressure quickly and easily, storing the results and displaying the progression of readings. A warning is issued for anyone suffering from cardiac arrhythmia. The values determined are classified and graphically evaluated according to WHO guidelines. Keep these instructions carefully for further use and also let other users have access to them.

Important information

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

Advice on use

• To ensure comparable values, always measure your blood pressure at the same time of day.
• Before every measurement, relax for about five minutes.
• If you want to perform several measurements on the same person, wait five minutes between each measurement.
• Do not measure within 30 minutes after eating, drinking, smoking or exercising.
• 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)!
• 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.
• 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.
• The device is only intended for the purpose described in these instructions for use. The manufacturer is not liable for damage resulting from improper or careless use.

Storage and Care

• The blood pressure monitor is made up of precision electronic components. Accuracy of readings and the
  instrument’s service life depends on careful handling.

• You should protect the device from impact, moisture, dirt, major temperature fluctuations and direct exposure to the sun’s rays.

• Never drop the device.

• Do not use near strong electromagnetic fields, i.e. keep it away from any radio systems and mobile phones.

• Only ever use the cuffs provided with the monitor or original replacement cuffs. Otherwise, erroneous results will be recorded.

• Do not press any buttons until the cuff is in position.

• If the instrument is not used for any length of time, we recommend removing the batteries.

Advice on batteries

• Batteries can be fatal if swallowed. You should therefore store the batteries and products where they are inaccessible to small children. If a battery has been swallowed, call a doctor immediately.
• Batteries should not be charged or reactivated with any other means, nor should they be taken apart, thrown in the fire or short-circuited.
• Remove the batteries from the instrument if they are worn out or if you are not going to use the instrument for any length of time. This prevents any damage as a result of leakage. Always replace all the batteries at the same time.
• Never use different types of batteries, battery brands or batteries with different capacities. You should preferably use alkaline batteries.

Repair and Disposal

• Batteries do not belong in domestic refuse. Used batteries should be disposed of at the collection points provided.
• Never open the instrument. If these instructions are not heeded, the warranty will be null and void.
• Never attempt to repair the instrument or adjust it yourself. We can no longer guarantee perfect functioning if you do.
• Repairs may only be performed by Customer Service or authorized dealers. However, always check the batteries and replace them if necessary before making any complaint.
• The appliance should be disposed of according to Regulation-WEEE (Waste Electrical and Electronic Equipment). In case of queries, please contact the municipal authorities responsible for waste disposal in your area.

Prepare measurement

Inserting battery

• Remove the battery cover (left side of the unit).
• Insert two 1.5 V micro batteries (alkaline, type LR 03).
• Make sure that you insert the batteries with the correct polarity as marked. Do not use rechargeable batteries.
• Replace the battery cover carefully.
• If the change battery icon is displayed, measurement is no longer possible and you must replace all the batteries.
• Used batteries do not belong in the household waste.
• You are legally obliged to dispose of the batteries. Dispose of them via your specialist electrical supplier or local collecting point for recyclable waste.
• Note: You will find these markings on batteries containing harmful substances: Pb = battery containing lead, Cd = battery containing cadmium, Hg = battery containing Mercury.

Setting date and time
It is vital to set a date and time. Only in this way is it possible to save and subsequently retrieve your measured values with the right date and time. Time is shown in 24-hour format.
Note: If you hold down M, you can set the values faster.

• Press and M simultaneously. The month starts flashing. Using the M button, set the month 1 to 12 and confirm with .
• Set the day, hour and minute and confirm in each case .

Measuring blood pressure

• Bare your left wrist, making sure that the circulation in the arm is not restricted by any clothes etc. that are too tight. Position the cuff on the inside of your wrist.
• Fasten the cuff with the Velcro fastening 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.

Correct posture

• Rest for approx. 5 minutes before each measurement. Otherwise, there may be divergences.
• You can measure while sitting or lying. 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. 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.
• In order not to distort the result, it is important to keep still during the measurement and not talk.

Measuring blood pressure

• Switch on the blood pressure monitor with the button.
• 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 increases further.
• As soon as a heart rate is detected, the heart rate symbol is displayed Heart rate, systolic and diastolic blood pressure are displayed.
• You can interrupt measurement at any time by pressing the 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.

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 of arrhythmia. Arrhythmia is a condition where 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 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.

WHO classification
By the guidelines/definitions of the World Health Organization and the latest findings, the measurements can be classified and assessed according to 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.

Range of blood pressure values| Systolic (in mmHg)| Diastolic (in mmHg)| Measure
---|---|---|---
Grade 3: Severe hypertension| ≥180| ≥110| Seek medical advice
Grade 2: Moderate hypertension| 160-179| 100-109| Seek medical advice
Grade 1: Mild hypertension| 140-159| 90-99| Have it checked regularly by doctor
High-normal| 130-139| 85-89| Have it checked regularly by doctor
Normal| 120-129| 80-84| Check it yourself
Optimal| <120| <80| Check it yourself

According to WHO Guidelines/Definitions and the latest findings, the test results can be classified and evaluated according to the following chart. The bar graph in the display and the scale on the unit indicate the range of the blood pressure that has been recorded. An acoustic evaluation of your measurement also follows. If the values for systolic and diastolic pressure are in two different WHO ranges (e.g. systolic in the high-normal range and diastolic pressure in the normal range) the graphic WHO classification on the unit indicates the higher range (high-normal in the example described).

Saving, retrieving and deleting results

• The results of each successful measurement are stored together with the date and time. With more than 60 items of measured data, the earliest items of data measured are lost.
• To retrieve measurement results again, press the memory button M. The instrument first displays the number of memory spaces occupied and then automatically switches to the last saved test result.
• If you continue pressing the memory button M, the last results in each case are measured are displayed with date, time and graphic WHO classification.
• You can clear the memory by holding down the memory button M for 3 seconds.

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 the above cases, you must repeat the measurement.
• Reinsert the batteries if necessary, or else replace them.

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 or. 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.
