NOTICES
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 arm each time.
6. Please always relax at least 1 or 1.5 minutes between measurements to allow the blood circulation in
your arm to recover. Prolonged over-inflation (cuff pressure exceed 300 mm Hg or maintained above 15
mm Hg 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;

8. This Electronic Sphygmomanometer is designed for adults and should never be used for 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. If an irregular heartbeat (IHB) from common arrhythmias is detected in the procedure of blood
pressure measurement, this sign will be displayed. Under this condition, the Electronic
Sphygmomanometers 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 the pulses is > 25 %.
2) The deviation of the following pulse period is ≥ 0.14 s, and the number of such pulses
amounts to more than 53 % of the total number of measured pulses.
12. Please do not use the cuff other than supplied by the manufacturer, otherwise it may bring
biocompatible hazard and might result in measurement error.
13. The monitor might not meet its performance specifications or cause a safety hazard if stored or
used outside the temperature and humidity ranges specified in the specifications.
