Do not move during measurement, it will have a delayed effect on the patient’s blood flow.
The device need to be placed for 2 hours from the minimum storage temperature to being ready for its intended use.
The device need to be placed for 4 hours from the highest storage temperature to being ready for its intended use.
Note
The following conditions may also cause changes in the blood pressure measurement value.
Take the measurement in one hour after meal or after drinking alcohol, coffee or after smoking, exercise, bathing;
Using incorrect posture such as standing or lying down, etc;
The patient speak or move his body during measurement;
When measuring, the patient is nervous, excited, emotional instability;
The room temperature rise or fall sharply, or the environment of measurement often changes;
Measuring in a moving vehicle;
The high and low location of cuff will cause changes in measurement results;
Continuous measurement for a long time.
7.2 Applying the Cuff
Both left and right arm can be measured.
Bare your arm or cloth close-fitting clothing during measurement.
Carry out the operation in a room with comfortable temperature.
When measuring, take the thick clothes off instead of rolling up the sleeves.
In order to measure accurately, pay attention to applying the cuff properly (left arm).
① Insert the arm cuff air plug in the cuff socket of sphygmomanometer.
② Stretch cuff into a barrel for the arm can conformable enter into the barrel
③ Left arm penetrate through the cuff, the air tube of the cuff will pass the top of your palm.
④ Wrap the cuff to your upper arm. Make the air tube inside the forearm and aligned with your middle finger.
⑤ The bottom of the cuff should be approximately 2cm~3cm above your elbow.
⑥ Be fixed with cloths, and wrapped tight cuff, the arm and the cuff should not have gaps.

7.3 Measurement BP
①Under “OFF” state, press “START/STOP” button to start measuring.
During measurement, please keep correct pose and quiet state, the body could not move.The “Movement” icon appears
if patient moves, and continue measuring may lead to inaccurate measurement.
If you want to abort the measurement
Press【START/STOP】button, the device will stop inflating, and release the air from the cuff.
Display the measurement results after finishing measuring.The pressure bar on the right side visually demonstrates the
pressure level.
7.4 Confirm the Measurement Value
①The World Health Organization has established globally accepted standards for the assessment of hypertension readings.(In the
clinic environment)
Severe Hypertension/High Blood
Pressure
Pressure bar at the right side
The SYS higher than 135mmHg or the DIA higher than 85mmHg are used as the criteria of hypertension(In the home environment),
and the pressure bar at the right side lights up in red.
The SYS lower than 135mmHg and the DIA lower than 85mmHg are used as the criteria of normal pressure, and the pressure bar
at the right side lights up all in green.
The number of lights represents the blood pressure range.
*Self-diagnosis and treatment using measured results may be dangerous. Follow the instructions of your physician.
7.5 Upload date(optional for devices with Bluetooth function)
①The data stored can be uploaded to master device by Bluetooth
Time sync icon lights up if the device time is not synced, and the measured data cannot be uploaded to the terminal
equipment via the Bluetooth. After syncing the time by Bluetooth connection of the device, Time sync icon goes off,
and the measured data can be uploaded
③After uploading the data to the master device, the local data will be deleted.
Note
Wait at least 4-5 minutes between measurements.
When repeatedly measuring, the accurate blood pressure value may not be measured due to congestion in the arm.
Please measure after the blood flow is smooth.
When the screen displays Err, the measure can't be carried out correctly.
Irregular pulse icon is displayed in the measurement results if the pulse internal is irregular during measuring,
which may cause it is unable to take measurement correctly. Please keep quiet and remeasure. If the irregular
pulse icon appears frequently, please consult a doctor.
The minimum value of the patient’s physiological signal is the minimum limit that the device can measure. The
device may obtain inaccurate measurement results when it is operated below the minimum amplitude or minimum
value of the patient’s physiological signal.
*The device will automatically turn off after five minutes in which there is no operation to the device, even if you
forget to turn the power off.
Chapter8 Memory Function
The device can store NIBP values automatically, display up to 199 set of measurement results.

data will be overwritten. If no measurement values, the memory values can be not numerated.
Memory function can not be used during measuring.
When there is no measurement values, “---” will display on the review interface.
8.1 Review the Memory Value
1.Under “OFF” state, press “M” button to display the average value of the latest three set of data, when the number of
measurement data is less than three groups, it will supplement automatically. Continue to press “M” button in current
interface to view all measurement records.
8.2 Delete Memory Values
1.Users can delete all memory values of the current user instead of separately delete one memory value
2.Under the memory interface, press “M” button and “START/STOP” button simultaneously for more than 5 s, after
“DEL” appears on the screen, all memory values will be deleted.
Caution
When querying the measurement records, please press “M” button continuously to query one by one.

a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey
should be considered. If the measured field strength in the location in which the the device is used exceeds the
applicable RF compliance level above, the the device should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the the device.

NOTE If necessary to achieve the IMMUNITY TEST LEVEL, the distance between the transmitting antenna and the
ME EQUIPMENT or ME SYSTEM may be reduced to 1 m. The 1 m test distance is permitted by IEC 61000-4-3.
a) For some services, only the uplink frequencies are included.
b) The carrier shall be modulated using a 50 % duty cycle square wave signal.
c) As an alternative to FM modulation, 50 % pulse modulation at 18 Hz may be used because while it does not
represent actual modulation, it would be worst case.
The MANUFACTURER should consider reducing the minimum separation distance, based on
RISK MANAGEMENT, and using higher IMMUNITY TEST LEVELS that are appropriate for the reduced minimum
separation distance. Minimum separation distances for higher IMMUNITY TEST LEVELS shall be calculated using the
following equation:
Where P is the maximum power in W, d is the minimum separation distance in m, and E is the IMMUNITY TEST
LEVEL in V/m.
