2. Important Information on Blood Pressure and its Measurement
2.1. How does high or low blood pressure arise?
Your level of blood pressure is determined in the circulatory center of the brain and adjusts to a
variety of situations through feedback from the nervous system. To adjust blood pressure, the
strength and speed of the heart (Pulse), as well as the width of circulatory blood vessels is
altered.Blood vessel width is controlled by fine muscles in the blood vessel walls.
Your level of arterial blood pressure changes periodically during heart activity: During the
“blood ejection” (Systole) the value is highest (systolic blood pressure value). At the end of the
heart’s “rest period” (Diastole) pressure is lowest (diastolic blood pressure value).
Blood pressure values must lie within certain normal ranges in order to prevent particular
diseases.
2.2. Which values are normal?
Please refer to the diagram below(Picture-01)

7
Picture-01
There are six grids in the display of device. Please refer to the picture-01-01. Different grids
represent different interval scales of WHO.
Picture-01-01
Blood pressure is very high if your diastolic pressure is above 90 mmHg and/or your systolic
blood pressure is over 160 mmHg, while at rest. In this case, please consult your physician
immediately. Long-term values at this level endanger your health due to continual damage to
the blood vessels in your body. If your systolic blood pressure values are between 140 mmHg
and 159mmHg and/or the diastolic blood pressure values between 90 mmHg and 99mmHg,
consult your physician. Regular self-checks are necessary. If you have blood pressure values
that are too low, (i.e., systolic values under 105mmHg and/or diastolic values under 60 mmHg),
consult your physician. Even with normal blood pressure values, a regular self-check with your
blood pressure monitor is recommended. You can detect possible changes in your values
early and react appropriately. If you are undergoing medical treatment to control your blood
pressure, keep a record of values along with time of day and date. Show these values to your
physician. Never use the results of your measurements to independently alter the drug doses
prescribed by your physician.
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 120mmHg require immediate

8
medical treatment.
2.3. What can be done if regular high or low values are obtained?
1) Consult your doctor.
2) Increased blood pressure values (various forms of hypertension) are associated with
considerable health risks over time. Arterial blood vessels in your body are endangered due to
constriction caused by deposits in the vessel walls (Arteriosclerosis). A deficient supply of
blood to important organs (heart, brain, muscles) can result from arteriosclerosis. Furthermore,
the heart will become structurally damaged with increased blood pressure values.
3) There are many different causes of high blood pressure. We differentiate between the
common primary (essential) hypertension, and secondary hypertension. The latter group can
be ascribed to specific organ malfunctions. Please consult your doctor for information about
the possible origins of your own increased blood pressure values.
4) There are measures which you can take to reduce and even prevent high blood pressure.

4.2. Cuff tube connection
Insert the cuff tube into the opening on the left side of the monitor indicated by the drawing of a
cuff.
5. Measurement Procedure
Note: You should always be seated and calm before and during measurement.
5.1. Before measurement:
• Avoid eating and smoking as well as all forms of exertion directly before measurement. These
factors influence the measurement result. Find time to relax by sitting in an armchair in a quiet
atmosphere for about ten minutes before taking a measurement.
• Remove any garment that fits closely to your upper arm.
• Always measure on the same arm (normally left).
• Always compare measurements taken at the same time of day, since blood pressure
changes during the course of the day, as much as 20-40 mmHg.
5.2. Common sources of error:
Note: Comparable blood pressure measurements always require the same conditions!
•Conditions should always be quiet.
•All efforts by the user to support the arm can increase blood pressure. Make sure you are in a
comfortable, relaxed position and do not flex any of the muscles in the measurement arm
during the measurement. Use a cushion for support if necessary.
• If the arm artery lies considerably lower or higher than the heart, an erroneously high or low
blood pressure will be measured! Each 25-30cm difference in height between your heart and
the cuff results in a measurement error of 10 mmHg!
Note: Only use approved cuffs!
• A loose cuff or a sideways protruding air pocket causes false measurement values.
• With repeated measurements, blood accumulates in the arm, which can lead to false results.
Consecutive blood pressure measurements should be repeated after a 1 minute pause or after
your arm has been held up in order to allow the accumulated blood to flow away. If you decide
to take your Averaging Mode measurement again, be sure to wait at least one minute
beforehand.

11
5.3. Fitting the Cuff
Please refer to picture-06
a) The cuff is preformed for easier use. Remove tight or bulky clothing from your upper arm.
b) Wrap the cuff around your upper left arm. The rubber tube should be on the inside of your
arm extending downward to your hand. Make certain the cuff lies approximately 1/2” to 3/4” (1
to 2 cm) above the elbow. Important! The on the edge of the cuff (Artery Mark) must lie
over the artery which runs down the inner side of the arm.
c) To secure the cuff, wrap it around your arm and press the hook and loop closure together.
d) There should be little free space between your arm and the cuff. You should be able to fit 2
fingers between your arm and the cuff. Cuffs that don’t fit properly result in false measurement
values. Measure your arm circumference if you are not sure of proper fit.
e) Lay your arm on a table (palm upward) so the cuff is at the same height as your heart. Make
sure the tube is not kinked.
f)Remain seated quietly for at least two minutes before you begin the measurement.
Picture-06
Change the cuff may result in unacceptable risks,the operator should pay attention to the
following:
• Only use Jamr authorized cuffs, as those not approved for use with the device may provide
inaccurate measurements, injury, and/or damage the device.
• Do not force cuff connection into the opening.
• Do not forcefully bend the arm cuff or air tube. Do not fold tightly.

d) When the measurement has been concluded, the measured systolic and diastolic blood
pressure values, as well as the pulse will be displayed.
e) The measurement results are displayed until you switch the device off. If no button is
pressed for 60 seconds, the device switches off automatically.
f) Cuff self-checking symbol (√×)
The cuff correct symbol(√) will be displayed if the cuff position is correct, otherwise the wrong
symbol(×) will be displayed. Please check again the cuff if the wrong symbol(×) is displayed.
g) Movement error symbol ( )
The Movement Error Symbol ( ) is displayed if you move your body during the
measurement. Please remove the cuff, and wait 2-3 minutes. Reapply the cuff and take
another measurement.
Recommended Use Methods:
1. Recommendation that the PATIENT relax as much as possible and not talk during the
measurement PROCEDURE.
2. Recommendation that 5 min should elapse before the first reading is taken.
3. Any reading can be affected by the measurement site, the position of the PATIENT,
exercise, or the PATIENT’S physiologic condition.
4. Performance of the AUTOMATED SPHYGMOMANOMETER can be affected by extremes
of temperature, humidity and altitude.
5. To stop the inflation or measurement, push the START/STOP button. The monitor will stop
inflating, start deflating, and will turn off.

5.5. Irregular Heartbeat Detector
This symbol - indicates that certain pulse irregularities were detected during the measurement.
In this case, the result may deviate from your normal basal blood pressure – repeat the
measurement.
Information for the doctor on frequent appearance of the Irregular Heartbeat Symbol
This instrument is an oscillometric blood pressure monitor device that also analyzes pulse
frequency during measurement. The instrument is clinically tested.
If pulse irregularities occur during measurement, the irregular heartbeat symbol is displayed
after the measurement. If the symbol appears more frequently (e.g. several times per week on
