User's Manual
Do  not  use  the  cuff  in  the  area  where  the  treatment  is  being  performed  inside  blood  vessel  or  the  arteriovenous 
connection. This may cause temporary blockage of blood flow and cause injury to the patient. 
Do not use the cuff on the side of the mastectomy. 
When using the cuff to pressurize, some of the body’s functions may temporarily weaken. Do not use the measurement 
medical electrical equipment at the appropriate arm position. 
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. 
① ②  ③ 
④ ⑤  ⑥ 
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)

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. 
If 199 set of measurement data have been stored in current device, when saving the 200th set of data, the earliest set of 
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.
