Stay healthy – Microlife Corporation!

• This device uses the same measuring technology as the award winning «BP 3BTO-A» model tested according to the British and Irish Hypertension Society (BIHS) protocol.

Important facts about blood pressure

• Blood pressure is the pressure of the blood flowing in the arteries generated by the pumping of the heart. Two values, the systolic (upper) value and the diastolic (lower) value, are always measured.
• The device indicates the pulse rate (the number of times the heart beats in a minute).
• Permanently high blood pressure values can damage your health and must be treated by your doctor!
• Always discuss your values with your doctor and tell them if you have noticed anything unusual or feel unsure. Never rely on single blood pressure readings.
• There are several causes of excessively high blood pressure values. Your doctor will explain them in more detail and offer treatment where appropriate.
• Under no circumstances should you alter the dosages of drugs or initiate a treatment without consulting your doctor.
• Depending on physical exertion and condition, blood pressure is subject to wide fluctuations as the day progresses. You should therefore take your measurements in the same quiet conditions and when you feel relaxed! Take at least two readings every time (in the morning: before taking medications and eating / in the evening: before going to bed, bathing or taking medication) and average the measurements.
• It is quite normal for two measurements taken in quick succession to produce significantly different results.
• Deviations between measurements taken by your doctor or in the pharmacy and those taken at home are quite normal, as these situations are completely different.
• Several measurements provide much more reliable information about your blood pressure than just one single measurement.
• Leave a small break of >5 minutes between two measurements.
• If you suffer from a cardiac arrhythmia consult with your doctor before using the device. See also chapter «Appearance of the  Pulse Arrhythmia (PAD)» of this user manual.
• The pulse display is not suitable for checking the frequency of heart pacemakers!
• If you are pregnant, you should monitor your blood pressure regularly as it can change drastically during this time.

A number of factors can affect the accuracy of measurements taken on the wrist. In some cases, the result may differ from the measurement taken on the upper arm. We therefore advise you to compare these values with those produced by the upper arm measurement and discuss them with your doctor

How do I evaluate my blood pressure

Table for classifying home blood pressure values in adults in accordance with the international Guidelines (ESH, ESC, JSH). Data in mmHg.

medical advice
5.| blood pressure dangerously high| ≥ 160| ≥ 100| Urgently seek medical advice!

The higher value is the one that determines the evaluation. Example: a blood pressure value of 140/80 mmHg or a value of 130/90 mmHg indicates «blood pressure too high».

Using the device for the first time

Inserting the batteries

After you have unpacked your device, first insert the batteries. The battery compartment 5 is on the bottom of the device. Insert the batteries (4 x 1.5 V, size AA), thereby observing the indicated polarity

Selecting the correct cuff

Microlife offers different cuff sizes. Select the cuff size to match the circumference of your upper arms (measured by close fitting in the centre of the upper arm).

Pre-shaped cuffs are optionally available.
Only use Microlife cuffs

Contact your local Microlife Service if the enclosed cuff 6 does not fit.

Connect the cuff to the device by inserting the cuff connector 7 into the cuff socket 3 as far as it will go.

Taking a blood pressure measurement

Checklist for taking a reliable measurement

1. Avoid activity, eating or smoking immediately before the measurement.

2. Sit down on a back-supported chair and relax for 5 minutes.
   Keep your feet flat on the floor and do not cross your legs.

3. Always measure on the same arm (normally left). It is recommended that doctors perform double arm measurements on a patients first visit in order to determine which arm to measure in the future. The arm with the higher blood pressure should be measured.

4. Remove close-fitting garments from the upper arm. To avoid constriction, shirt sleeves should not be rolled up – they do not interfere with the cuff if they are laid flat.

5. Always ensure that the correct cuff size is used (marking on the cuff).

   • Fit the cuff closely, but not too tight.
   • Make sure that the cuff is positioned 1-2 cm above the elbow.
   • The artery mark on the cuff (ca.3 cm long bar) must lie over the artery which runs down the inner side of the arm.
   • Support your arm so it is relaxed.
   • Ensure that the cuff is at the same height as your heart.

6. Press the ON/OFF button 1 to start the measurement.

7.  The cuff will now pump up automatically. Relax, do not move and do not tense your arm muscles until the measurement result is displayed. Breathe normally and do not talk.

8. When the correct pressure is reached, the pumping stops and the pressure falls gradually. If the required pressure was not reached, the device will automatically pump some more air into the cuff.

9. During the measurement, the pulse indicator AM flashes in the display.

10. The result, comprising the systolic 9, the diastolic AT and the pulse rate AK are displayed.

11. When the device has finished measuring, remove the cuff.

12. Switch off the device. (The monitor does switch off automatically after approx. 1 min.)

You can stop the measurement at any time by pressing the ON/OFF button or open the cuff (e.g. if you feel uneasy or an unpleasant pressure sensation).

If the systolic blood pressure is known to be very high, it can be an advantage to set the pressure individually. Press the ON/OFF button after the monitor has been pumped up to a level of approx. 30 mmHg (shown on the display). Keep the button pressed until the pressure is about 40 mmHg above the expected systolic value – then release the button.

Appearance of the Pulse Arrhythmia (PAD)

This symbol AP indicates that certain pulse irregularities were detected during the measurement. In this case, the result may deviate from your normal blood pressure – repeat the measurement. In most cases, this is no cause for concern. However, if the symbol appears on a regular basis (e.g. several times a week with measurements taken daily) we advise you to tell your doctor. Please show your doctor the following explanation:

Information for the doctor on frequent appearance of the Arrhythmia indicator

This device is an oscillometric blood pressure monitor that also analyses pulse frequency during measurement. The device is clinically tested.

The arrhythmia symbol is displayed after the measurement, if pulse irregularities occur during measurement. If the symbol appears more frequently (e.g. several times per week on measurements performed daily) we recommend the patient to seek medical advice.

This device does not replace a cardiac examination, but serves to detect pulse irregularities at an early stage.

Traffic light indicator in the display

The bars on the left-hand edge of the display AL show you the range within which the indicated blood pressure value lies. Depending on the height of the bar, the readout value is either within the optimum (green), elevated (yellow), too high (orange) or dangerously high (red) range. The classification corresponds to the 4 ranges in the table as defined by the international guidelines (ESH, ESC, JSH), as described in «Section 1.».

Data memory

This device always stores the last result at the end of the measurement. To recall the reading, press and hold the ON/OFF button 1 while the device is switched off. Release the button as soon as all display elements are shown. The stored result will then be shown, indicated with the letter «M» 17.

Battery indicator and battery change

Low battery

When the batteries are approximately ¾ empty the battery symbol 8 will flash as soon as the device is switched on (partly filled battery displayed). Although the device will continue to measure reliably, you should obtain replacement batteries.

Flat battery – replacement

When the batteries are flat, the battery symbol 8 will flash as soon as the device is switched on (flat battery displayed). You cannot take any further measurements and must replace the batteries.

1. Open the battery compartment 5 on the bottom of the device.
2. Replace the batteries – ensure correct polarity as shown by the symbols in the compartment.

Which batteries and which procedure?

•  Use 4 new, long-life 1.5 V, size AA alkaline batteries.
•  Do not use batteries beyond their date of expiry.
•  Remove batteries if the device is not going to be used for a prolonged period.

Using rechargeable batteries

You can also operate this device using rechargeable batteries.

• Only use «NiMH» type reusable batteries.
• Batteries must be removed and recharged when the flat battery symbol appears. They should not remain inside the device as they may become damaged (total discharge as a result of low use of the device, even when switched off).
• Always remove the rechargeable batteries if you do not intend to use the device for a week or more.
• Batteries cannot be charged in the blood pressure monitor. Recharge batteries in an external charger and observe the information regarding charging, care and durability.

Using a mains adapter

You can operate this device using the Microlife mains adapter (DC 6V, 600 mA).

• Only use the Microlife mains adapter available as an original accessory appropriate for your supply voltage.
• Ensure that neither the mains adapter nor the cable are damaged

1. Plug the adapter cable into the mains adapter socket 4 in the blood pressure monitor.
2. Plug the adapter plug into the wall socket. When the mains adapter is connected, no battery current is consumed
