2. Getting ready for measurement
2.1. Inserting the batteries
To insert batteries
1. Remove the cover as illustrated.
2. Insert the batteries (4 AA, 1.5 V), following the indicated
polarity. (+ -)
ATTENTION
• If a battery warning appears in the display,
the batteries are almost at and must be re-
placed. And after battery warning appears,
the device will not work until batteries have
been replaced.
• If the blood pressure monitor is not used for
long periods, remove the batteries from the de-
vice.
• Please use “AA” Long-Life or Alkaline 1.5V Bat-
teries. Do not use rechargeable batteries.
• Functional check: Hold the START button down to test all the
display elements. When functioning correctly many icons will
appear.
2.2. Cu connection
Insert the cu tube into the opening provided on the side of
the device as shown in the picture.
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
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.
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.
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.
2-3cm
3.2. Measuring procedure
To carry out measurement
1. Press the START button. The device is
switched on. Many icons appear in the dis-
play for 2 seconds. A short double beep fol-
lows to indicate that the device is ready. A
«0» is shown in the display.
2. Grasp the pumping bulb with your free
hand and Inate the cu to a pressure at least
40 mmHg higher than the expected systolic
pressure. If you do not know the value of this
pressure, inate to a value of approximately
160–180 mmHg. The cu pressure is shown
continuously on the display.
3. After the ination process lay down the
pumping bulb and remain in a quiet and re-
laxed sitting position.
The measurement now proceeds on its
own.
If no measurement takes place and all
that appears in the display is a ashing, up-
wards pointing arrow , pump the ball once
again and inate to a higher pressure (see
clause Inating further given below). When
the device detects a pulse, a heart symbol in
the display starts to ash and a beep is heard
for every heart beat.

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.
The cu pressure can now be quickly re-
leased by pressing the quick release valve at
the pumping bulb.
Note
To prolong the batteries’ life the device
switches o automatically if no button is
pressed for 3 minutes. Otherwise you can
switch it o by pressing the START button.
3.4. Inating further
If the cu is not inated suciently, the
measurement is stopped after a few seconds
and a ashing arrow pointing upwards
appears in the display. It is then necessary
to inate at least 20 mmHg higher than the
previous value. The instruction to inate fur-
ther can appear several times if the pressure
is still not sucient.
ATTENTION:
If the cu is inated too far (over 300
mmHg), appears in the display and a
warning signal is sounded. The cu pressure
must then be immediately released using the
quick-release valve at the pumping bulb!
3.5. Discontinuing a measurement
If it is necessary to interrupt a blood pres-
sure measurement for any reason (e.g the
patient feels unwell), the quick-release valve
at the pumping bulb can be pressed at any
time. The device then immediately lowers
the cu pressure automatically.
3.6. 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
Semi-automatic Blood Pressure Monitor
GammaTM Model M1-S 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)
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 (diastolic blood pressure can’t be meas-
ured). The tube may have loosened after the systo-
lic pressure has been determined. Pulse could not
be detected.
ERR 2 Unnatural pressure impulses inuence the meas-
urement result. Reason: the arm was moved during
the Measurement (Artefact)
ERR 5 The measuring signals are inaccurate and no re-
sult can therefore be displayed. Read through the
checklist for performing reliable measurements
and then repeat the measurement.*
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:
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 you are
inating the bulb.
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.
Please re-read the clause Measuring
procedure above.
Blood pressure values
dier from those meas-
ured at the doctor’s.
Record daily values and consult your
doctor.
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 con-
ditions! 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.
ATTENTION
Should any technical malfunctions arise in the blood pressure
monitor, please contact the point of sale where you bought the
device or Service Centre Gamma-Medica. Never attempt to re-
pair the instrument yourself!
Any unauthorized opening of the instrument invalidates all
warrantee claims.
6. Care and maintenance
Do not expose the device to either extreme
temperatures, humidity, dust or direct
sunlight.

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

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-
plicationsofhypertensionmightbe kidneydamages,breast-pang,
paralytic stroke, aphasia, dementia, heart attack and stroke.
9.2. Which values are normal?
The world standard as for the norms of the blood pressure is

• The diagnosis of hypertension requires from the patient to
combine medical treatment prescribed by the doctor and
mode of life correction.
• People with normal pressure and high normal pressure are rec-
ommended to carry out self-control of their tension in order
to timely take measures to decrease the blood pressure level
down to the optimal one without using any medications.
• For people more than 50 years old high level of systolic blood
pressure (higher than 140 mmHg) is more crucial than diasto-
lic pressure.

-Aftermedicalexaminationplease
regularly go in for sports, with the
following restrictions:
• go in for endurance exercises
not strengthening exercises.
• do not train till complete ex-
haustion.
• if you have any chronic diseas-
es and/or you are older than 40
please consult your doctor before
you start going in for sports.
- Spend at least half an hour out in
the open air every day.
4 – 9 mmHg
• Even with blood pressure being normal, people run the bigger
risk of hypertension development with advancing age.
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
per day)!
2 – 8 mmHg
- Avoid eating fat food! Introduce
to your diet some food that is rich
in dietary ber (fruits, vegetables)
8 – 14 mmHg
- Refuse from smoking outright!
- Use only limited amount of alco-
hol (bier – 350 g, or vine – 150 g,
or vodka – 50 g)!
- Restrain the usage of caeine
(coee)!
2 – 4 mmHg
