2. Using the Instrument for the First Time

Inserting the batteries

After you have unpacked your device, first insert the batteries. The

battery compartment

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 different cuff sizes. Select the cuff size to match the

circumference of your upper arms (measured by close fitting in the

centre of the upper arm).



Optional preformed cuffs «Easy» are available.



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 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 AT flashes in the

display and a beep sounds every time a heartbeat is detected.

10.The result, comprising the systolic

and the diastolic

blood

pressure and the pulse

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.

12.Switch off the instrument. (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

pressure sensation).

4. Appearance of the Heart Arrhythmia Indicator for

early Detection

This symbol AN indicates that certain pulse irregularities were

detected during the measurement. In this case, the result may

deviate from your normal blood pressure – repeat the measure-

ment. 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

measurements taken daily) we advise you to tell your doctor.

Please show your doctor the following explanation:

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)

M - L 22 - 42 cm (8.75 - 16.5 inches)

Information for the doctor on frequent appearance of the

Arrhythmia indicator

This instrument is an oscillometric blood pressure monitor that

also analyses pulse frequency during measurement. The instru-

ment is clinically 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.

The instrument does not replace a cardiac examination, but

serves to detect pulse irregularities at an early stage.
