2. Using the Instrument 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 size AA 1,5 V), 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 instrument 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
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 cuff is positioned correctly, as shown in
the pictures illustrated on the short instruction card.
• Fit the cuff closely, but not too tight.
• Make sure that the cuff is 2 cm (0.75 inch) above your elbow
with the tube on the inside of your 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.
