2.2. What is blood pressure?
Blood pressure is the pressure created in the blood vessels by each heart beat. When
the heart contracts (= systole) and pumps blood into the arteries, it brings about a rise
in pressure. The highest value is known as the systolic pressure and is the first value
to be measured. When the cardiac muscle relaxes to take in fresh blood, the pressure
in the arteries also falls. Once the arteries are relaxed, a second reading is taken – the
diastolic pressure.
2.3. How is blood pressure measured?
The 3NF1-2B is a blood pressure unit which is used to measure blood pressure at the
upper arm. The measurement is carried out by a microprocessor, which, via a pressure
sensor, measures the vibrations resulting from the inflation and deflation of the cuff
over the artery.
2.4. Why should you take your blood pressure at home?
Microlife has had many years of experience in the field of blood pressure measure-
ment. The high precision of Microlife devices has been confirmed by extensive clinical
tests, carried out according to strict international standards. One strong argument in
favour of taking blood pressure at home is the fact that the readings are taken in
familiar surroundings under relaxed conditions. The most important reading is the
socalled „baseline value“, the one taken before breakfast, directly after getting up in
the morning. As far as it is possible, you should always try to take your blood pressure
at the same time and under the same conditions each day.
This ensures comparable results and helps in detecting the first signs of high blood
pressure. If high blood pressure remains undetected, it increases the risk of further
cardiovascular diseases.
THEREFORE WE RECOMMEND:
Take a blood pressure reading daily and on a regular basis, even if you are experienc-
ing no apparent complaints.
2.5. Blood pressure classification
The following standards for assessing high blood pressure (in adults) have been
established by the National Institutes of Health JNC7, 2003.
Category Systolic Diastolic
(mmHg) (mmHg)
Normal <120 and <80
Pre-Hypertension 120-139 or 80-89
Hypertension
Stage 1 Hypertension 140-159 or 90-99
Stage 2 Hypertension ≥160 or ≥100

+Further information
• If your values are mostly normal under resting conditions but exceptionally high
under conditions of physical or psychological stress, it is possible that you are
suffering from so-called "labile hypertension." Consult your doctor.
• Correctly measured diastolic blood pressure values above 120 mmHg require
immediate medical treatment.
Hypertension risk indicator
The bars on the left-hand edge of the display show you the range within which the
indicated blood pressure value lies. Depending on the height of the bar, the readout
value is either within the normal (green), borderline (yellow) or danger (orange, red)
range.
The classification is based on standards established by the National Institutes of
Health JNC7, 2003.
The traffic light bar illuminates according to your measurement.
• If your measurement has only the green bar,
your measurement is "Normal," according
to NIH standards.
• If your measurement shows the yellow bar, your measurement is "Pre-Hypertension."
• If your measurement shows the orange bar, it is "Stage 1 Hypertension."
• If your measurement shows the red bar, it is "Stage 2 Hypertension."

WARNING
Blood pressure that is too low represents just as great a health risk as blood pressure
that is too high! Fits of dizziness may lead to dangerous situations arising (e.g. on
stairs or in traffic)!
2.6. Fluctuations in blood pressure
There are many factors that can influence blood pressure. Readings can be affected
seriously by stress, fear, heavy physical exertion or the time of day at which the
measurements are taken. Your personal blood pressure values are subject to consider-
able fluctuation during the course of the day and the year. These fluctuations are
particularly pronounced in the case of patients suffering from hypertension. Blood
pressure is usually at its highest during physical exertion and at its lowest at night
when you are asleep.
2.7. Influencing and evaluating readings
• Measure your blood pressure several times, then record and compare the results. Do
not draw any conclusions from a single reading.
• Your blood pressure readings should always be evaluated by a doctor who is also
familiar with your personal medical history. When using the unit regularly and
recording the values for your doctor, you should visit the doctor from time to time to
keep him updated.
• When taking readings, remember that the daily values are influenced by several
factors. Smoking, consumption of alcohol, drugs and physical exertion influence the
measured values in various ways.
• Measure your blood pressure before meals.
• Before taking readings, allow yourself at least five minutes rest.
• If the systolic and diastolic readings seem unusual (too high or too low) on several
occasions, despite correct use of the unit, please inform your doctor. This also
applies to the rare occasions when an irregular or very weak pulse prevents you
from taking readings.
3. Getting Started
3.1. Inserting / removing batteries
Insertion: Open the battery compartment on the underside of the unit by exerting
gentle pressure in the direction indicated by the arrow, and insert the four batteries
included with the unit (alkaline batteries, AA type, LR 6). Remember to insert the
batteries as indicated in the diagram in the battery compartment. Once the batteries
are inserted correctly (or once the power unit is plugged in), you should hear 2 beeps.
2G-IB-edit for NF1-2B_rev_2.3:MLU3AC1-JAN05-2 14-11-20 10:25 Page 11
12
When the ON/OFF switch is activatedV, you will hear 2 beeps and all the symbols
appear on the display for one second. Then the following appears: “ - : - - “. Replace
the lid, pressing it until it snaps into place.
Removal:
If the voltage in the batteries drops below 5 - 4.5 V, the display shows the battery
symbol as. Switch the device off using the ON/OFF switch V and insert new batter-
ies. Should the used batteries be jammed in the compartment, use a pointed instru-
ment, such as a ballpoint pen, to carefully prise them out.
As soon as the voltage in the batteries drops below 4.25 - 0.25 V, the display shows
the battery symbolas . The device automatically switches off immediately after this
symbol appears. The device will not function until new batteries are inserted.
Note that you have to reset the date and time each time you replace the batteries,
unless this is set automatically via the radio clock when the device is switched on
using the ON/OFF switch V. The previous measuring results are saved.

3.2. Using a mains adaptor
Alternatively, you can also run the device using a special power supply unit. Connect it
to at on the back ofthe device. In this case the batteries remain in the unit.
Inserting the connector into the back of the blood pressure monitor switches the batter-
ies off mechanically. It is necessary, therefore, to plug the mains adaptor into the mains
socket first of all and then to connect it to the blood pressure monitor. If the blood
pressure monitor is no longer being used, first remove the connector from the blood
pressure monitor and then pull the mains adaptor out of the mains socket. Doing this
means that the date and time will not have to be reset each time.

15
• 3 consecutive readings ( Measurement Average Mode = 3/MAM-mode )
In the case of a single reading, just one blood pressure reading is taken and stored.
The 3/MAM-mode is to be recommended if you suffer from severely fluctuating blood
pressure. 3 successive readings are taken at 15 second intervals, thus eliminating
widely varying readings. In the case of serious deviations, a 4th reading may be taken.
From these three measurements, a weighted average value is calculated, displayed
and stored in the selected memory. A reading taken in this way is indicated in the
memory by an bk .
The 3/MAM procedure greatly minimizes the risk of an incorrect reading.
1. To switch between single measurement and 3 consecutive measurements (3MAM
procedure), press and hold the TIMER button Wuntil the symbol for 3MAM mode
and “ “ appear flashing in the display.
2. Press the MEMO button x to select either “ “ or “ “; “ “ for the

elbow region. If wearing tight clothing, ensure that the circulation in the arm is not
impaired when rolling up the sleeve.
The tube should run along the centre of the inner arm towards the palm of the hand.
Ensure that the cuff itself is not twisted in any way.
Fasten the pressure cuff in such a way that it fits tightly but does not constrict the arm.
4.2. Correct position for taking readings
• Take readings while in a seated position.
• Relax your arm and rest it lightly on a surface such as a table. Relax during the
measuring process: do not move or talk, as this can affect the results.
4.3. Taking blood pressure readings
Single reading
To take a single measurement, you have to switch on the device using the ON/OFF
switch V and be in standby mode. You first have to complete any settings you require

1. Press the START button . The device carries out a self test. Once this is complete, “
“ appears on the display. 5 short beeps sound during the procedure.
2. Next, the sleeve u automatically inflates until the pressure required for a measure-
ment has been reached. Alternatively, you can create this pressure manually by
pressing and holding the START button wafter the device has automatically
reached a pressure of at least 30 mmHg. When you think that the device has
reached the ideal starting pressure for a measurement, release the START button
w. The increasing pressure is displayed numerically.
3. The measuring process begins automatically when inflation is complete by releasing
the pressure built up in the cuff. The display shows the current pressure in the cuff.
NOTE
If you press the START button wwhen the device is inflating, the inflation process
stops. The device switches off and the air escapes from the sleeve.
4. Initially, deflation occurs at a constant speed. The pulse symbol ap appears on
the display. As soon as the pulse can be determined, deflation is synchronised with
the beating of the heart until the measurement ends. The device beeps for each
2G-IB-edit for NF1-2B_rev_2.3:MLU3AC1-JAN05-2 14-11-20 10:25 Page 16

hand. At the same time, the pulse symbol apflashes.
5. Once the measurement has been taken, the sleeve suddenly deflates and a longer-
beep sounds.
6. The measured valuesam ,an and ao are shown on the display, together with the
JNC7 blood pressure bar displaybm . At the same time, a longer beep sounds.
7. If the unit detects an arrhythmia during the measuring process, the arrhythmia
symbol ar will flash eight times while the reading is displayed. You may also
hear 8 short beeps; these warn the user of an irregular heartbeat.
8. If you do not press any buttons for approx. 1 minute, the device automatically
switches to standby mode.
3MAM measuring method
(3 consecutive measurements to calculate an average value)
To take a single measurement, you have to switch on the device using the ON/OFF
switch V and be in standby mode. You have selected the 3MAM measuring method
(see section 3, subsection 3.6). You first have to complete any settings you require as

1. Press the START button w. The device carries out a self test. Once this is
complete, “ “ appears on the display. 5 short beeps sound during the procedure.On
the display, you can see bk (average) and “ 1“ for the first measurement.
2. Next, the sleeve uautomatically inflates until the pressure required for a
measurement has been reached. Alternatively, you can create this pressure manually
by pressing and holding the START button w after the device has automatically
reached a pressure of at least 30 mmHg. When you think that the device has
reached the ideal starting pressure for a measurement, release the START button
w. The increasing pressure is displayed numerically.
3. The measuring process begins automatically when inflation is complete by releasing
the pressure built up in the cuff. The display shows the currentpressure in the cuff.
4. Initially, deflation occurs at a constant speed. The pulse symbol ap appears on
the display. As soon as the pulse can be determined, deflation is synchronised with
the beating of the heart until the measurement ends. The device beeps for each
heartbeat during this procedure, if you did not switch off the beep function before-
hand. At the same time, the pulse symbol ap flashes.

5. The first measurement ends when the pressure has been completely discharged
from the sleeve during a 15 second countdown. The countdown symbol bl flashes
during this process. Beeps sound during the last 5 seconds.
6. Instead of “ 1“, the display now shows “ 2“ for the second measurement. The
second measurement proceeds in the same way as the first (see points 2 - 5).
7. Instead of “ 2 “, the display now shows “ 3 “ for the third measurement. The third
measurement proceeds in the same way as the first (see points 2 - 4).
8. Once the 3MAM measurement has been taken, the sleeve suddenly deflates and a
longer beep sounds.
9. The measured values am , an and ao are shown on the display, together with the
WHO blood pressure bar display bm . At the same time, a longer beep sounds.
10.If the unit detects an arrhythmia during the measuring process, the arrhythmia
symbol ar will flash eight times while the reading is displayed. You may also
hear 8 short beeps; these warn the user of an irregular heartbeat.
11.If you do not press any buttons for approx. 1 minute, the device automatically
switches to standby mode.
NOTE
When the device is used, the errors Err 1, 2, 3, 5, 6 can occur in the integrated circuit.
Err 6 can only occur in 3MAM mode. In 3MAM mode, errors Err 1, 2, 3, 5 do not cause
the measurement to be cancelled, unless they occur twice in succession. The error
display is always accompanied by 3 short beeps.
4.4. Troubleshooting
Error messages
Possible causes and solutions
Err 1
Measurement of the systolic blood pressure was completed.
Either the connection with the hose has been interrupted or no pulse could be
determined.
Check the connections between the cuff and the main unit.
Err 2
Non-physiological pressure has been detected.
Cause: the arm was moved during the measurement.
Repeat the measurement, keeping your arm still.
2G-IB-edit for NF1-2B_rev_2.3:MLU3AC1-JAN05-2 14-11-20 10:25 Page 18
19
Err 3
If the cuff takes too long to inflate, it is possible that the cuff is incorrectly positioned
or that the connection with the hose is not airtight.
Check the connections and repeat the measurement.
Err 5
An average value could not be calculated due to unstable conditions while the
readings were being taken.
Repeat the measuring process, keeping your arm still and not speaking.
Err 6
There were too many errors during the measurement in MAM mode, making it impossi-
ble to obtain a final result.
Read through the checklist for performing reliable measurements and then repeat the
measurement.
HI
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.
LO
The pulse is too low (less than 40 beats per minute).
Repeat the measurement.
4.5. Switching off the unit
