Model M1-S-1
INSTRUCTION BOOK
Thank you for choosing our Semi-automatic Blood Pressure
Monitor GammaTM designed on the basis of the most advanced
technologies. The device you are holding now is your reliable as-
sistant. You can measure your blood pressure with this monitor
as accurately and precisely as an experienced doctor or a skilled
nurse would do it.
We are sure that having appraised worthily the high quality
and reliability of this device you will become a regular user of the
products of Gamma Trade Mark.
Before starting to use this device please study the instruction
book carefully. The instruction book oers all information you
need to correctly measure your blood pressure and pulse.
Regular blood pressure control allows for reliable and easy
health monitoring and for eective combating possible compli-
cations caused by blood pressure abnormalities.
ATTENTION
This blood pressure monitor is designed to carry out self-con-
trol over blood pressure but NOT to make self-diagnosis of hy-
pertension/hypotension. Please DO NOT diagnose by yourselves
basing on the measurement results obtained with the blood pres-
sure monitor. Please DO NOT execute self-treatment of high/low
blood pressure and DO NOT change the methods prescribed
without consulting your doctor.

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
• After low battery indicator appears, the device
won’t function until the batteries have been re-
placed.
• 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 ON/OFF 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.

3.2. Measuring procedure
To carry out measurement
1. Press ON/OFF button, device is
switched on, where you will see many seg-
ments display for about 2 secs, then there
ashes a downward triangle, which means
device is automatically lowering pressure
left in the cu, you can hold down quick re-
lease valve to speed up the process.
2. Once cu pressure is completely re-
leased, you will hear 3 short beeps, with a
steady“0”shows on
3. Grasp the pumping bulb with your free
hand and inate the cu, during which an
upward triangle keeps ashing.
4. Stop pumping when the upward trian-
gle terminates ashing, device then starts to
deate.
5. Lay down the pumping ball and re-
main in a quiet and relaxed sitting position.
The measurement now proceeds on its own
and is taken automatically.

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
values, as well as the pulse are now dis-
played, and there ashes a downward trian-
gle indicating people to release the rest of air
pressure in the cu.
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 ON/OFF 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 ap-
pears in the display. It is then necessary to in-
ate at least 20 mmHg higher than the previ-
ous value till cu pressure displays again on
the LCD.The instruction to inate further 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.

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. Further possible
reason: 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 measured reading indicated an unacceptible
dierence between systolic and diastolic pres-
sures. Take another reading following directions
carefully. Contact your doctor if you continue to
get unusual readings.
Other possible errors and their solutions
If problems occur when using the device, the following points
should be checked:
