3. Measurement Procedure
ATTENTION
• Findtimetorelaxbysittinginaquietatmosphereforsome
time before measurement.
• Eorts by the patient to support the arm can increase the
blood pressure. Make sure you are in a comfortable, relaxed
position and do not activate any muscles in the arm during
measurement.
• Alwaysmeasureonthesamearm(normallyleft).
• Removeanygarmentthattscloselytoyourupperarm.Do
not roll the sleeve since it can squeeze your hand and this can
lead to false results.
• Useonlyclinicallyapprovedoriginalcu
• Ifyouwanttofollowtheresultsofyourbloodpressuremeas-
urements, always perform measurements at the same time of
tne day, since blood pressure changes during the course of
the day.
• Measurementsshouldbedoneaftera5minuteresttoensure
accuracy.
3.1. Fitting the cu
1. Pass the end of the cu through the at
metal ring so that a loop is formed, and the
velcro faсes outwards.
2. Place the cu over the left upper arm
so that tube is closer to your lower arm.
3.Laythecuonthearmsothatthelow-
er edge of the cu lies approximately 2 to 3
cm above the elbow.
2-3cm

9
4. Tighten the cu by pulling the end and
close the cu by axing the velcro. There
should be little free space between the arm
andthecu.Cuthatdoesnottproperly
results in false measurement values. Cloth-
ing must not restrict the arm. Any piece of
clothing which does must be removed.
5.Layyourarmonatablesothecuisat
the same height as your heart. If the upper
arm artery lies considerably lower or higher
than the heart, a false higher or lower blood
pressure will be measured! A variation of 15
cm between cu and heart level can result in
a reading error of + or - 10mm Hg.
Make sure the tube is not kinked.
6. Remain seated quietly for two minutes
before you begin the measurement.
3.2. Measuring procedure
To carry out measurement
1.  Press the START button. The built-in
microprocessor begins to inate the cu. In
the display, the increasing cu pressure is
continually displayed.
2. After automatically reaching an in-
dividual pressure, the pump stops and the
pressure slowly falls. The cu pressure is dis-
played during the measurement. When the
device has detected your pulse, the heart
symbol in the display begins to blink and a
beep tone is audible for every pulse beat.

10
3.3. Reading measurement results
When the measurement has been con-
cluded, a long beep tone sounds. The meas-
ured systolic and diastolic blood pressure val-
ues, as well as the pulse are now displayed.
The appearance of this symbol sig-
nies that an irregular heartbeat was de-
tected. This indicator is only a caution. It is
important that you be relaxed, remain still
and do not talk during measurements.
Note: We recommend contacting your physician if you see
this indicator frequently.
To prolong the batteries’ life the device
switches o automatically if no button is
pressed for 1 minute. Otherwise you can
switchitobypressingtheSTARTbutton.
3.4. Discontinuing a measurement
If it is necessary to interrupt a blood pres-
sure measurement for any reason (e.g the
patientfeelsunwell),theSTART buttoncan
be pressed at any time. The device then im-
mediately lowers the cu pressure automati-
cally.
3.5. Irregular Heartbeat Detector
This function indicates allorhythmic heartbeating. If the sym-
bol of IHD appears on the display that means that certain ab-
normality in heart beat frequency was detected during the meas-
urement. In this case, the result may deviate from your normal
blood pressure – repeat the measurement. 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:
Information for the doctor on frequent appearance of
the Irregular Heartbeat Detector
This instrument is an oscillometric blood pressure monitor
that also analyses pulse frequency during measurement. The in-
strument is clinically tested.
The symbol is displayed after the measurement, if pulse ir-
regularities 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 ad-
vice.
The instrument does not replace a cardiac examination, but
serves to detect pulse irregularities at an early stage.
4. Memory function
Automatic Blood Pressure Monitor Gam-
maTM Model M1-1 automatically stores the
result measured.
To see the result of the last measurement
press and hold the START/MEMORY button
for at least 3 seconds.
If an irregular heartbeat interval was de-
tected in the measurement stored in memo-
ry, the icon will be displayed.
5. Error Messages/Troubleshooting
If an error occurs during a measurement,
the measurement is discontinued and a cor-
respondingerrorcodeisdisplayed(picture:
error no. 2)

12
Error No. Possible cause(s) / Solutions
ERR1 The systolic pressure was determined, but then
the pressure in the cu went down to less than 20
mmHg. Pulse could not be detected. The tube may
have loosened after the systolic pressure has been
determined.Furtherpossiblecase:Nopulsecould
be detected.
ERR2 Unnatural pressure impulses prevent from accu-
rate measuring the blood pressure.
Reason:Thearmwasmovedduringthemeasure-
ment. (artefact)
Repeat measurement following the above rules.
ERR3 If ination of the cu takes too long, the
cu is not correctly seated or the hose
connection’s not tight.
ERR5 The dierence between systolic and diastolic is ex-
cessive. Measure again carefully following proper
procedures. Consult your doctor if you still get un-
usual results of measurements.
HI The pressure in the cu 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.*
*Please consult your doctor, if this or any other problem oc-
curs repeatedly.
Other possible errors and their solutions
If problems occur when using the device, the following points
shouldbechecked:

13
Malfunction Remedy
The display remains
blank when the device
is switched on although
the batteries are in
place.
1. Check battery installation/ polar-
ity.
2. Remove the batteries and if the dis-
play is unusual, then exchange them
for new ones.
The pressure does not
rise although the pump
is running.
Check the connection of the cu tube
and connect properly.
The device frequently
fails to measure, or the
values measured are
too low or high.
1. Fit the cu correctly on the arm.
2. Before starting measurement make
sure that clothing is not exerting
pressure on the arm. Take articles of
clothing o if necessary.
Measure blood pressure again in
complete peace and quiet.
Everymeasurementre-
sults in dierent values,
although the device
functions normally and
normal values are dis-
played.
1. Please re-read the points listed un-
der“MeasuringProcedure”
2. Blood pressure changes constantly.
The observed readings may accurate-
ly reect your pressure-minor dier-
ences in the readings are not abnor-
mal.
Blood pressure values

cemaybehigherduetoanxiety.
After the instrument
has inated the cu the
pressure falls very slow-
ly, or not at all.
Check cu connections.

Note
Blood pressure is subject to uctuations even in healthy peo-
ple. Please remember that comparable blood pressure meas-
urements always require the same time and the same condi-
tions! These are normally quiet conditions. If you follow the
correct procedures described above and still get the uctuations
of blood pressure of more than 15 mmHg and/or you repeatedly
hear irregular pulse tones please consult your doctor.

9. Important information on blood pressure and its
measurement
9.1. What is blood pressure?
Blood pressure is the pressure that your blood extends to the
vascular walls. Blood pressure is necessary to provide for constant
blood ow inside the body. Thanks to it the cells get oxygen that
provides for their normal functioning. The heart performs the
function of a“pump”, sending blood to the blood vessels. Each
heart beat creates a certain level of the blood pressure.
There are 2 kinds of blood pressure: a systolic (upper) one,
which corresponds to the heartbeat pushing blood into the arte-
riae; and a diastolic (lower) one, which means the blood pressure
between two heartbeats.
SYS blood pressure
DIA blood pressure

18
Blood pressure is subject to uctuations during the day even
in healthy people. The uctuations are inuenced by a number of
factors – time of day, person’s condition, physical or mental activ-
ity, environment, etc.
Day-Night Fluctuations of the Blood Pressure
An increase of blood pressure increases the burden onto the
heart, aects blood vessels making their walls thick and less elas-
tic. One of the features of the hypertension is its ability to remain
unnoticed for the patient at its early stages. That’s why the self-
control of the blood pressure is so important. With the illness
progressing, headaches and regular dizziness appear, the sight
declines, the functioning of vitalses (encephalon, heart, kidneys,
blood vessels) breaks down. Without special treatment the com-
plicationsof hypertensionmightbe kidney damages,breast-pang,
paralytic stroke, aphasia, dementia, heart attack and stroke.

ATTENTION
If you have normal results of blood pressure measured under
calm conditions but your results are excessively high when meas-
ured under the conditions of physical or mental exhaustion, this
might be a sign of so called brittle (that is unstable) hypertension.
If you suspect that, please consult your doctor.
When measured correctly, if diastolic blood pressure is more
than 120 mmHg, it is necessary to call the doctor immediately.
9.3.What can be done to lower/maintain the level of blood
pressure?
Recommendation
How much the
systolic blood
pressure can
be lowered
- Try to maintain the weight which
is considered standard for your
age. Decrease overweight if any!
5 – 20 mmHg
with every 10
kilos of weight
reduction
- Avoid salt overuse (it’s recom-
mended to use no more than 6 g
