Important Facts about Blood Pressure and SelfMeasurement

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 him/her 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. Besides medication, weight loss and exercise can also lower your blood pressure.
Under no circumstances should you alter the dosages of drugs or initiate 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 and in the evening) 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 at least 15 seconds between two measurements.
If you suffer from a cardiac arrhythmia consult with your doctor before using the device. See also chapter «Appearance of the Irregular Heartbeat (IHB) Symbol» 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.

Range

| Systolic| Diastolic|

Recommendation

---|---|---|---

| blood pressure normal| < 120| < 74| Self-check

| blood pressure optimum| 120 – 129| 74 – 79| Self-check

| blood pressure elevated| 130 – 134| 80 – 84| Self-check

| blood pressure too high| 135 – 159| 85 – 99| Seek medical advice

| 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 3 is at the top of the device. Insert the batteries (2 x 1.5 V, size AAA), thereby observing the indicated polarity.

Setting the date and time

After the new batteries are fitted, the year number flashes in the display. You can set the year by pressing the M-button 5. To confirm and then set the month, press the time button 6.
Press the M-button to set the month. Press the time button to confirm and then set the day.
Follow the instructions above to set the day, hour, and minutes.
Once you have set the minutes and pressed the time button, the date and time are set and the time is displayed.
If you want to change the date and time, press and hold the time button down for approx. 3 seconds until the year number starts to flash. Now you can enter the new values as described above.

Taking a Blood Pressure Measurement

Checklist for taking a reliable measurement

Avoid activity, eating or smoking immediately before the measurement.
Sit down on a back-supported chair and relax for 5 minutes. Keep the feet flat on the floor and do not cross your legs.
Always measure in a sitting position and on the same wrist. Use the wrist which usually shows higher blood pressure values.
Remove any items of clothing and your watch, for example, so that your wrist is free.
Always ensure that the cuff is positioned correctly, as shown in the pictures illustrated on the short instruction card.
Fit the cuff comfortably but not too tight. The cuff will cover a wrist circumference of 13.5 – 21.5 cm (5.25 – 8.5 inches).
Press the ON/OFF button 1 to start the measurement.
The LED Positioning Indicator AR is activated. Support your arm in a relaxed position with the device at the same height as your heart, move your arm until the LED light is at its brightest and appears to be in the center of the indicator.
After 5 seconds, the cuff will 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.
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.
During the measurement, the pulse indicator AN flashes in the display.
The result, comprising the systolic 7 and the diastolic 8 blood pressure and the pulse rate 9 is displayed.
Note also the explanations on further display symbols in this booklet.
13.Remove and switch off the monitor and enter the result in the enclosed blood pressure pass. (The monitor does switch off automatically after approx. 1 min.).

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

Appearance of the Irregular Heartbeat (IHB) Symbol

This symbol AM indicates that an irregular heartbeat was detected. In this case, the measured blood pressure may deviate from your actual blood pressure values. It is recommended to repeat the measurement.

Information for the doctor in case of repeated appearance of the IHB symbol:
This device is an oscillometric blood pressure monitor that also measures the pulse during blood pressure measurement and indicates when the heart rate is irregular.

Traffic Light Indicator in the Display

The bars on the left-hand edge of the display AK 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), asdescribed in «Section 1.».

Data Memory

At the end of each measurement, this device automatically stores the result, including date and time.

Viewing the stored values

Press the M-button 5 briefly, when the device is switched off. The display first shows «M» AL and then a value, e.g. «M 17». This means that there are 17 values in the memory. The device then switches to the last stored result. Pressing the M-button again displays the previous value. Pressing the Mbutton repeatedly enables you to move from one stored value to another.

Memory full

Pay attention that the maximum memory capacity of 60 memories is not exceeded. When the 60 memory is full, the oldest value is automatically overwritten with the 61st value. Values should be evaluated by a doctor before the memory capacity is reached – otherwise data will be lost.

Clearing all values

If you are sure that you want to permanently remove all stored values, hold down the M-button (the device must have been switched off beforehand) until «CL» appears and then release the button. To permanently clear the memory, press the M-button while «CL» is flashing. Individual values cannot be cleared.

How not to store a reading

As soon as the reading is displayed press and hold the ON/OFF button 1 until «M» AL is flashing. Confirm to delete the reading by pressing the M-button 5.

Battery Indicator and Battery change

Low battery

When the batteries are approximately ¾ empty the battery symbol AO 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 AO will flash as soon as the device is switched on (flat battery displayed). You cannot take any further measurements and must replace the batteries.

Open the battery compartment 3 by pulling off the cap.
Replace the batteries – ensure correct polarity as shown by the symbols in the compartment.
To set date and time, follow the procedure described in «Section 2.».

The memory retains all values although date and time must be reset – the year number therefore flashes automatically after the batteries are replaced.

Which batteries and which procedure?

Use 2 new, long-life 1.5 V, size AAA 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.

Error Messages

If an error occurs during the measurement, the measurement is interupted and an error message, e.g. «ERR 3», is displayed.

Error	Description	Potential cause and remedy
«ERR 1»	Signal too weak	The pulse signals on the cuff are too weak.

Reposition the cuff and repeat the measurement.
«ERR 2» AP| Error signal| During the measurement, error signals were detected by the cuff, caused for instance by movement or muscle tension. Repeat the measurement, keeping your arm still.
«ERR 3» AQ| No pressure in the cuff| An adequate pressure cannot be generated in the cuff. A leak may have occurred. Check that the cuff is correctly connected and is not too loose. Replace the batteries if necessary. Repeat the measurement.
«ERR 5»| Abnormal result| The measuring signals are inaccurate and no result can therefore be displayed. Read through the checklist for performing reliable measurements and then repeat the measurement.
«HI»| Pulse or cuff pressure too high| The pressure in the cuff is too high (over 299 mmHg) OR the pulse is too high (over 200 beats per minute). Relax for 5 minutes and repeat the measurement.
«LO»| Pulse too low| The pulse is too low (less than 40 beats per minute). Repeat the measurement.

Please immediately consult your doctor, if this or any other problem occurs repeatedly.
If you think the results are unusual, please read through the information in «Section 1.» carefully.
