1. Important Facts about Blood Pressure and Self­Measurement



Blood pressure

generated by the pumping of the heart. Two values, the
(upper) value and the

 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.

 Enter your readings in the enclosed blood pressure diary. This

will give your doctor a quick overview.



There are many causes of excessively

values

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, 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?

2. blood pressure

5. blood pressure far

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

Inserting the batteries

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

Selecting the correct cuff

Microlife offers 3 different cuff sizes: S, M and L. Select the cuff size to
match the circumference of your upper arms (measured by close fitting
in the centre of the upper arm). M is the correct size for most people.

Cuff size for circumference of upper arm

S 17 - 22 cm (6.75 - 8.75 inches)
M 22 - 32 cm (8.75 - 12.5 inches)
L 32 - 42 cm (12.5 - 16.5 inches)

Only use Microlife cuffs.





Contact Microlife Service if the enclosed cuff 5 does not fit.



Connect the cuff to the device by inserting the cuff connector 6
into the cuff socket 3 as far as it will go.

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 on the same arm (normally left).

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 2 cm above the elbow.
 The artery mark located 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 heart symbol AT flashes in the
display and a beep sounds every time a heartbeat is detected.

10.The result, comprising the systolic 7 and the diastolic 8 blood
pressure and the pulse 9 is displayed and longer beep is heard.
Note also the explanations on further displays in this booklet.

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 (e.g. if you feel uneasy or an unpleasant pres­sure sensation).

4. 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
device is switched off. All display elements are shown now. Release the
button when the stored result with the letter «

5. Battery Indicator and Battery change

Low battery

When the batteries are approximately ¾ empty the battery symbol AK
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 AK 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 4 at the back of the device.

while the

is displayed.

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 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.

6. Error Messages

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

movement or muscle tension. Repeat the
measurement, keeping your arm still.

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.

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.*

The pressure in the cuff is too high (over
300 mmHg) OR the pulse is too high (over
200 beats per minute). Relax for 5 minutes
and repeat the measurement.*
