IMPORTANT INFORMATION
NORMAL BLOOD PRESSURE FLUCTUATION
All physical activity, excitement, stress, eating, drinking, smoking, body posture and many other activities or
factors (including taking a blood pressure measurement) will influence blood pressure value. Because of this, it is
mostly unusual to obtain identical multiple blood pressure readings.
Blood pressure fluctuates continually day and night. The highest value usually appears in the daytime and lowest
one usually at midnight. Typically, the value begins to increase at around 3:00AM, and reaches to highest level in
the daytime while most people are awake and active.
Considering the above information, it is recommended that you measure your blood pressure at approximately
the same time each day.
Too frequent measurements may cause injury due to blood flow interference, please always relax a minimum
moment of 1 to 1.5 minutes between measurements to allow the blood circulation in your arm to recover. It is rare
that you obtain identical blood pressure readings each time.

NOTICE
1. Read all of the information in the operation guide and any other literature in the box before operating the
unit.
2. Stay still, calm and rest for 5 minutes before blood pressure measurement.
3. The cuff should be placed at the same level as your heart.
4. During measurement, neither speak nor move your body and arm.
5. Measuring on same wrist for each measurement.
6. Please always relax a minimum moment of 1 to 1.5 minutes between measurements to allow the blood
circulation in your arm to recover. Prolonged over-inflation (cuff pressure exceed 300 mmHg or maintained
above15 mmHg for longer than 3 minutes) of the bladder may cause ecchymoma of your arm.
7. Consult your physician if you have any doubt about below cases:
1) The application of the cuff over a wound or inflammation diseases;
2) The application of the cuff on any limb where intravascular access or therapy, or an arterio-venous (A-V)
shunt, is present;
3) The application of the cuff on the arm on the side of a mastectomy;
4) Simultaneously used with other monitoring medical equipments on the same limb;
5) Need to check the blood circulation of the user.
8. This Electronic Sphygmomanometer is designed for adults and should never be used on infants or
young children. Consult your physician or other health care professionals before use on older children.
9. Do not use this unit in a moving vehicle, This may result in erroneous measurement.

10. Blood pressure measurements determined by this monitor are equivalent to those obtained by a trained
observer using the cuff/stethoscope auscultation method, within the limits prescribed by the American
National Standard Institute, Electronic or automated sphygmomanometers.
11. Information regarding potential electromagnetic or other interference between the blood pressure monitor
and other devices together with advice regarding avoidance of such interference please see part
ELECTROMAGNETIC COMPATIBILITY INFORMATION.
12. If Irregular Heartbeat (IHB) brought by common arrhythmias is detected in the procedure of blood pressure
measurement, a signal of will be displayed. Under this condition, the Electronic Sphygmomanometer
can keep function, but the results may not be accurate, it’s suggested that you consult with your physician
for accurate assessment.
There are 2 conditions under which the signal of IHB will be displayed:
1) The coefficient of variation (CV) of pulse period >25%.
2) The difference of adjacent pulse period≥0.14s, and the number of such pulse takes more than 53
percentage of the total number of pulse.
13. Please do not use the cuff other than supplied by the manufacturer, otherwise it may bring biocompatible
hazard and might result in measurement error.
14. The monitor might not meet its performance specifications or cause safety hazard if stored or used
outside the specified temperature and humidity ranges in specifications.
15. Please do not share the cuff with other infective person to avoid cross-infection.
16. This blood pressure monitor is verified by auscultatory method. It is recommended that you check annex B
of ANSI/AAMI SP-10:2002+A1:2003+A2:2006 for details of verification method if you need.
17. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses 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:
—Reorient or relocate the receiving antenna.
—Increase the separation between the equipment and receiver.
—Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

monitor has no measurement stored in the memory, the LCD will display ―0‖ for blood pressure and pulse
rate. See picture 8-2.
d. If the voice function is switched on, the monitor will speak out measurement tips.
e. Then the monitor inflates the cuff until sufficient pressure has built up for a measurement. Then the
monitor slowly releases air from the cuff and carries out the measurement. Finally the blood pressure
and pulse rate will be calculated and displayed on the LCD. See picture 8-3. The irregular heartbeat
symbol (if any) and blood pressure classification indicator will blink on the screen. The result will be
automatically stored in the memory. If the voice function is on, it will announce the measurement result.
f. After measurement, the monitor will turn off automatically after 1 minute of no operation. Alternatively,
you can press the ―START‖ button to turn off the monitor manually.
g. During measurement, you can press the ―START‖ button to turn off the monitor manually.
Note: Please consult a health care professional for interpretation of pressure measurements.
9. DISPLAYING STORED RESULTS
a. Ensure the touch button switch in ON position.
b. Press ―MEM‖ button in Clock Mode. The amount of results will be displayed. See picture 9.
c. Then the last result will be displayed with date and time. See picture 9-1. The irregular heartbeat symbol
(if any) and blood pressure classification indicator will blink at the same time. If the monitor has no result
stored in the memory, the LCD will display ―0‖ for blood pressure and pulse rate. See picture 9-2.

11. ASSESSING HIGH BLOOD PRESSURE FOR ADULTS
The following guideline for assessing high blood pressure (without regard to age or gender) has been
established by the World Health Organization (WHO). Please note that other factors (e.g. diabetes, obesity,
smoking, etc.) need to be taken into consideration. Consult with your physician for accurate assessment, and
never change your treatment by yourself.
Note: It is not intended to provide a basis of any
type of rush toward emergency
conditions/diagnosis based on the color scheme
and that the color scheme is meant only to
discriminate between the different levels of blood
pressure.

12. TECHNICAL ALARM DESCRIPTION
The monitor will show 'SYS HI','SYS Lo' ,'DIA HI' or 'DIA Lo' as technical alarm on LCD with no delay if the
determined blood pressure (systolic or diastolic) is outside the rated range specified in part SPECIFICACIONS.
In this case, you should consult a physician or check if your operation violated the instructions.
The technical alarm condition (outside the rated range) is preset in the factory and cannot be adjusted or
inactivated. This alarm condition is assigned as low priority according to IEC 60601-1-8.
The technical alarm is non-latching and need no reset. The signal displayed on LCD will disappear automatically
after about 8 seconds.
