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 indi-
cates «blood pressure too high».
The slot-in card 3 on the front of the instrument shows ranges
1-6 in the Table.
2. Using the Instrument for the First Time
Activating the fitted batteries
Pull out the protective strip from the battery compartment 7.
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.

Only use Microlife cuffs.
 Contact Microlife Service if the enclosed cuff 8 does not fit.
 Connect the cuff to the instrument by inserting the cuff
connector 9 into the cuff socket 4 as far as it will go.
3. Taking a Blood Pressure Measurement using this
Instrument
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 instrument will automatically pump some more air into the cuff.
9. During the measurement, the heart symbol AN flashes in the
display and a beep sounds every time a heartbeat is detected.
10.The result, comprising the systolic AT and the diastolic AK blood
pressure and the pulse
AL is displayed and longer beep is heard.
Note also the explanations on further displays in this booklet.
11.When the measurement has finished, remove the cuff and pack
it into the instrument as shown in Fig. II.
12.Enter the result in the enclosed blood pressure pass and switch
off the instrument. (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).
