1. Important Facts about Blood Pressure and Self-
Measurement
• 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.
• 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.
•Enter your readings in the enclosed blood pressure diary. This
will give your doctor a quick overview.
• There are many causes of excessively high blood pressure
values
. Your doctor will explain them in more detail and offer treat-
ment where appropriate. Besides medication, relaxation techniques,
weight loss and exercise can also lower your blood pressure.
•Under no circumstances should you alter the dosages of any
drugs prescribed by 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 condi-
tions and when you feel relaxed! Take at least two measure-
ments per day, one in the morning and one in the evening.
•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 a much clearer picture than just
one single measurement.
•Leave a small break of at least 15 seconds between two
measurements.
•If you are pregnant, you should monitor your blood pressure very
closely as it can change drastically during this time!
•If you suffer from an irregular heartbeat (arrhythmia, see
«Section 4.»), measurements taken with this device should only
be evaluated after consultation with your doctor.
•The pulse display is not suitable for checking the frequency
of heart pacemakers!

How do I evaluate my blood pressure?
The higher value is the one that determines the evaluation. Example:
a readout value between 150/85 or 120/98 mmHg indicates «blood
pressure too high».
2. Using the Device for the First Time
Activating the fitted batteries
Pull out the protective strip from the battery compartment 3.
Setting the date and time
1. 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.
2. Press the M-button to set the month. Press the time button to
confirm and then set the day.
3. Follow the instructions above to set the day, hour and minutes.
4. Once you have set the minutes and pressed the time button, the
date and time are set and the time is displayed.
5. 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.
3. Taking a Blood Pressure Measurement using this
Device
Checklist for taking a reliable measurement
1. Avoid activity, eating or smoking immediately before the measurement.
2. Sit down for at least 5 minutes before the measurement and relax.
3. Always measure in a sitting position and on the same wrist. Use
the wrist which usually shows higher blood pressure values.

4. Remove any items of clothing and your watch, for example, so
that your wrist is free.
5. Always ensure that the cuff is positioned correctly, as shown in the
pictures illustrated on the short instruction card.
6. Fit the cuff comfortably but not too tight. The cuff will cover a wrist
circumference of 13.5 to 21.5 cm (5.25 - 8.5 inches).
7. Support your arm in a relaxed position and ensure that the device
is at the same height as your heart.
8. Press the ON/OFF button 1to start the measurement.
9. 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.
10.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.
11.During the measurement, the heart symbol AN flashes in the
display and a beep sounds every time a heartbeat is detected.
12.The result, comprising the systolic 7 and the diastolic 8 blood
pressure and the pulse rate
9 is displayed and a long beep is heard.
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 auto-
matically 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 pres-
sure sensation).
4. Appearance of the Heart Arrhythmia Indicator for
early Detection
This symbol AM 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 measure-
ments 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 clin-
ically 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.

5. User Selection
This blood pressure monitor allows you to store the results for 2 indi-
vidual users. In addition, there is a guest mode, in which the results
are not stored.
Alternating between 2 users or the guest mode
1. While the unit is switched off keep the time button 6pressed for
3 seconds until the user symbol AP or AQ starts to flash.
2. Press the M-button 5to change between user 1, user 2 and the
guest mode.
3. Confirm the selection by pressing the start button 1.
6. 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 5briefly, 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 M-button repeatedly enables you to move from one stored value
to another.
The user symbol AP or AQ indicates which user's memory is being
displayed. To change the user, please follow the instructions above.
In the guest mode no memories are stored or displayed.
Memory full

Pay attention that the maximum memory capacity of 99 memo-
ries per user is not exceeded.
When the 99 memory is full, the
oldest value is automatically overwritten with the 100th
value.
Values should be evaluated by a doctor before the
memory capacity is reached – otherwise data will be lost.
Clearing all values of an individual user
The following procedure applies for the selected user (AP or AQ).
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 1until «M» AL is flashing. Confirm to delete the reading by

replaced.
8. 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.
1. Open the battery compartment 3by pulling off the cap.
2. Replace the batteries – ensure correct polarity as shown by the
symbols in the compartment.
3. To set date and time, follow the procedure described in «Section 2.».

The memory retains all values although date and time (and
possibly also set alarm times) must be reset – the year number
therefore flashes automatically after the batteries are replaced.
