3.5  Heartbeat Readings

Besides Systolic and Diastolic values, 
Pulse will also be displayed after a 
measurement

Pulse

Irregular Heartbeat
This unit has a unique feature that alerts user of irregular 
heartbeat detection during measurement.

Note: An irregular heartbeat is defined as a 
           heartbeat rhythm that has a variation 
           of more than 25% from the average 
           rhythm detected during 
           measurement.

If such irregular rhythm occurs twice or 
more during the same measurement, the 
display screen will show the pulse value 
and “IH” symbol alternately.Example:  
(90 / IH)

Note:  Please consult your doctor if 
            irregular heartbeat occurs often.

Regular but Below Normal Heartbeat
If the monitor detects a pulse rate below 
60 beats per minute during measurement, 
the monitor will display the pulse value and 
“LO” symbol alternately. Example:  (58/LO)

If the monitor detects a pulse rate above 
100 beats per minute during measurement, 
the monitor will display the pulse value and
 “HI” symbol alternately. Example:  (102 / HI)

Regular but Above Normal Heartbeat

FCC Statement 
This equipment has been tested and found to comply with 
the limits for a Class B digital device, pursuant to part 15 of 
FCC Rules. These limits are designed to provide reasonable 
protection against harmful interference in a residential 
installation. This equipment generates and can radiate 
radio frequency energy and, if not installed and used in 
accordance with the instructions, may cause harmful 
interference to radio communications. However，there is 
no guarantee that interference will not occur in a particular 
installation. If this equipment does cause harmful 
interference to radio or television reception，which can 
be determined by turning the equipment off and on， the 
user is encouraged to try to correct the interference by one 
or more of the following measures: 

Attention： Don’t disassemble，repair and renovation 
                             ontology。

When the screen display the battery for one degree，it means
that low Voltage and must change the new one to void to
measure error。

- The monitor uses the oscillometric method to measure 
  systolic and diastolic blood pressure, as well as heart rate;

- This device is intended for use in measuring blood 
  pressure and pulse rate in the adult population, do not use 
  this device on infants or persons who cannot express their 
  intentions;
  The monitor is not intended to be a diagnostic device, It is 
  a home healthcare product only and it is not intended to 
  serve as a substitute for the advice of a physician or 
  medical professional.

- Don't not use this device for diagnosis or treatment of any 
  health problem or disease, Measurement results are for 
  reference only, consult a healthcare professional for 
  interpretation of pressure measurements, Contact your 
  physician if you have or suspect any medical problem. Do 
  not change your medications without the advice of your 
  physician or healthcare professional；

- Use only Truly authorized parts and accessories. Parts and 
  accessories not approved for use with the device may 
  damage the unit. and get a error of measurement;

- Proper cuff size is critical for accurate measurements, 
  Follow the instructions in this manual and printed on the 
  arm cuff to ensure the appropriate size of cuff is being 
  used; 

- Blood pressure measurement can be affected by the 
  position of the user，his or her physiologic condition and 
  other factors;Position of the user such as bending over the 
  body or cross-legged sitting will produce abdominal 
  pressure or make the position of the arm below the heart, 
  that will increase the blood pressure;

- This product is not suitable for people with arrhythmias or 
  serious arteriosclerosis. It may have difficulty determining 
  the proper blood pressure for pregnant women and for 
  users with irregular heartbeat,diabetes, pre-eclampsia, 
  poor circulation of blood, measurement on the arm on the 
  side of a mastectomy,kidney problems or for users who 
  have suffered from a stroke;

- When measurement,The pressurization of the cuff to arm 
  where intravascular access or therapy, or an arterio-
  venous(A-V) shunt, is present because of temporary 
  interference to blood flow  and could result in injury to the 
  patient;

- When measurement, The pressurization of the wrist can 
  temporarily cause function of simultaneously used 
  monitoring other device on the same limb;

- The pulse display is not suitable for checking the 
  frequency of heart pacemakers;

- Do not use a cellular phone near the device, It may result 
   in an operational failure;

- Do not use the monitor in the driving or flying vehicles；

- Frequenly measuring will make the blood not flow, cause 
  the arm-numbness and abnormal reaction of body；

- When you are using the monitor to measure especially 
  frequently used, the arm is compressed by the cuff, and 
  then the fingertip will be caused congestion. During the 
  congestion, please loosen the cuff and lift the hands over 
  your head, and make your right and left hand squeese and 
  stretch 15 times, them will unclog the congestion；

- Do not applying the CUFF over a wound, as this can cause 
   further injury；

- When measurement, please check that operation of the 
  device does not result in prolonged impairment of the 
  circulation of the blood of the patient；

- Do not compress the cuff tube during the measurement, 
  or it will cause fail inflation or affect the result of 
  measurement；

- Please use the product in the approved operate 
  environment, or will cause the inaccurate result of 
  Handling batteries properly: measurement；

- Dispose of the device, components and optional 
  accessories according to applicable local regulations, 
  Unlawful disposal may cause environmental pollution.

Don’t calling around the Blood pressure monitor when it is 
using ,Don’t move and avoid electromagnetic interference 
and noise interference when measuring that to avoid to 
measure error。

- Babies, young children or individuals who cannot express 
  their consent are not suitable to take blood pressure 
  measurement.

- Blood pressure readings may change in case of 
  pregnancy. Pregnant women can consult their doctor 
  before taking measurement.

- Individuals with serious arteriosclerosis are not suitable 
   to take blood pressure measurement.

- Keep the equipment away from children and pets.

- Do not disassemble, repair and alteration body.

- Self-measurement is not medical treatment. If there are 
   unusual values, please consult your doctor.

- Handling batteries properly:
   -  As soon as old batteries run out, replace with new 
      batteries.

Avoid smoking, eating or exercising for 30 minutes before 
taking measurement
