Attention:
To avoid damaging the device, keep this unit away from children and pets.
The standard material used for the bladder and tubing is latex-free.
Self-measurement means control, not diagnosis or treatment. Unusual values
must always be discussed with a physician. Under no circumstances should you
alter the dosages of any drugs prescribed by a physician.

contact time is less than 10 minutes.
Note: To obtain the greatest accuracy from your blood pressure instrument, it is
recommended that the instrument be used within the specified temperature and
the relative humidity, please see the Technical Specifications.
Note: The cuff is treated as the applied part.The user should contact the manufacturer
for assistance, if needed, in setting up, using or maintaining the device.
Note: Do not attempt to service or repair this device yourself. Should a malfunction
occur, refer to local distributor or the manufacturer.
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).
2.2. Which values are normal?
Please refer to the diagram below(Picture-01)
2.Important Information on Blood Pressure and Its Measurement

4.2. System Settings
Before setting, ensure that the battery power is enough.
charging indicator
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 wrist.
• Always measure on the same wrist (normally left).
5. Measurement Procedure
5.2. Fitting the Cuff
Please refer to picture-04
a) Remove all jewelry and watches. The palm of your hand should be facing you. Apply
the cuff so that the display is facing you.
b) The distance between the cuff and the hand should be 1-1.5cm.
c) Secure the cuff with the hook and loop adhesive so that it lies comfortably and not too
tight. It should be comfortable.
d) Lay your arm on a table with your palm upwards. Support your arm with a cushion so
that the cuff rests at about the same height as the heart. Remain still for 2 minutes, sitting
quietly, before beginning a measurement.
5.3. Measure Procedure
The device is designed to take measurements and store the measurement values in
memory for two people using User ID 1 and User ID 2.
Refer to picture-05
1. Sit comfortably in a chair with your feet flat on the
floor.
2. Select your User ID (1 or 2).
Stretch your arm forward on the desk and keep relaxing,
make sure the palm of hand is upturned. Make sure
wrist is in correct position, to avoid body movement. Sit
still and do not talk or move during the measurement.
After the cuff has been appropriately positioned on the
wrist and connected to the blood pressure monitor, the
measurement can begin:

1-1.5cm
Picture-05
Keep the machine at the
same height as the heart
when measuring
Operate on the device
a) Press the START/STOP button. The pump begins to inflate the cuff. In the display, the
increasing cuff pressure is continually displayed.
Recommended Use Methods
1.Recommendation that the user 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 user,
exercise, or the user’s physiologic condition.
4.Performance of the AUTOMATED SPHYGMOMANOMETER can be affected by
extremes of temperature, humidity and altitude.
b) After automatically reaching an individual pressure, the pump stops and the pressure
slowly falls. The cuff pressure is displayed during the measurement.
c) When the device has detected your pulse, the heart symbol in the display begins to blink.
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) 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.
NOTE:
User Position:
1) Comfortably seated 2) Legs uncrossed
3) Feet flat on the floor 4) Back and arm supported
5) Middle of the CUFF at the level of the right atrium of the heart
6) Relax your wrist and hand. Do not bend your wrist back, clench your fist, or bend your
wrist forward.Refer to Picture-06
5.To stop the inflation or measurement, push the START/STOP button. The monitor will
stop inflating, start deflating, and will turn off.
6.After the monitor has detected your blood pressure and pulse rate, the cuff
automatically deflates. Your blood pressure and pulse rate are displayed.
Picture-06
5.4. 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 measurements performed daily) or if it suddenly appears more often
than usual, we recommend the user to seek medical advice. The instrument does not
replace a cardiac examination, but serves to detect pulse irregularities at an early stage.
a) Press the START/STOP button, the pump begins to inflate the cuff. In the display, the
increasing cuff pressure is continually displayed.
b) After automatically reaching an individual pressure, the pump stops and the pressure
slowly falls. The cuff pressure is displayed during the measurement.
c) When the device has detected your pulse, the heart symbol in the display begins to
blink.
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 appearance of this symbol signifies that an irregular heartbeat was detected.
This indicator is only a caution. It is important that you be relaxed, remain still and do not
talk during measurements.
f) 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.
