1.2 Warnings and Precautions

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)

Attention:
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.
The pulse display is not suitable for checking the frequency of heart
pacemakers!
In cases of irregular heartbeat, measurements made with this instrument should
only be evaluated after consultation with a physician.
The temperature of contact parts with the patient is as high as 41.3 ℃, and the
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.

Battery Installation
Use only 1.5V “AAA” alkaline batteries with this device.
1. Press the hook on the bottom of the battery cover and lift the cover off in the direction
of the arrow.
2. Install 2 “AAA” size batteries so the + (positive) and - (negative) polarities match the
polarities of the battery compartment, replace the battery cover.Make sure that the
battery cover is securely in position.
Battery replacement
Low Battery Indicator
1.When the Low Battery Indicator appears on the display, turn the monitor off and remove
all the batteries. Replace with 2 new batteries at the same time. Long-life alkaline
batteries are recommended.

Note:
You can’t delete all measurement record from the monitor storage at one time, if you
decide to delete the all record, please keep the record in another way, in case you need
it some days later. Take the battery out won’t lead to a record missing.
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 1cm.
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
Refer to picture-05
The monitor is designed to take measurements and store the measurement values in
memory for two people using User ID A and User ID B.
1. Sit comfortably in a chair with your feet flat on the floor.
2. Select your User ID (A or B).
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:
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 measurement results are displayed until you switch the device off. If no button is
pressed for 60 seconds, the device switches off automatically.
NOTE:
Patient 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
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
Picture-04

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.
6.After the monitor has detected your blood pressure and pulse rate, the cuff
automatically deflates. Your blood pressure and pulse rate are displayed.
7.The monitor will automatically turn off after one minute.
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 patient to seek medical advice. The instrument does not
replace a cardiac examination, but serves to detect pulse irregularities at an early stage.
Picture-05
Keep the machine at the same
height as the heart when measuring
