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 is at the back of the device. Insert the batteries
(4 x 1.5 V, size AA), thereby observing the indicated polarity.

Selecting the correct cuff

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)

BP A90
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.
