The monitor features blood pressure measurement, pulse rate measurement and auto-save the result. The design provides you with two years of reliable service. Reading taken by the LS810-B are equivalent to those obtained by a trained observer using the cuff and stethoscope auscultation method. This manual contains important safety and care information, and provides step by step instructions for using the product. Read the manual thoroughly before using the product. FEATURES:
Pulse Rate Memory: Up to 60 pieces of records Systolic Blood Pressure Diastolic Blood Pressure Measurement Principle This product uses the Oscillometric Measuring Method to detect blood pressure. Before every measurement, the unit establishes a zero point equivalent to the atmospheric pressure. Then it starts inflating the cuff. Meanwhile, the unit detects pressure oscillation generated by beat-to-beat pulsatile, which is used to deter-
mine the systolic pressure and diastolic pressure as well as pulse rate. The device also compares the longest and the shortest intervals of detected pulse wave to with the average value, and then calculates the standard deviation. The monitor will light up a warning symbol when the calculated standard deviation is larger than or equal to 15.

ABOUT BLOOD PRESSURE Systolic blood discharging artery What are systolic pressure and diastolic pressure?
When ventricles contract and pump blood out of the heart, the blood pressure reaches its maximum value in the cycle, which is called systolic pressure. When the ventricles relax, the blood pressure reaches its minimum value in the cycle, which is called diastolic pressure. What is the standard blood pressure classification?
The blood pressure classification published by World Health Organization (WHO) and International Society of Hypertension (ISH) in 1999 is as follows:
Diastolic blood entering vein press relax M E M S E T MEM SET Avoid shaking and collision. Avoid dusty environment and unstable temperature surrounding CAUTION Only a physician can tell your normal BP range. Please contact a physician if your measuring result falls out of the range. Kindly note that only a physician could tell whether your blood pressure value has reached a dangerous point. MEM SET Use the slightly damp cloth to remove the dirt.

During each measurement, this equipment records the heartbeat intervals and works out the standard deviation. If the calculated value is larger than or equal to 15, this equipment will light up the IHB symbol on the screen when displaying the measuring result. CAUTION The appearance of the IHB icon indicates that a pulse irregularity consistent with an irregular heartbeat was detected during measurement. Usually this is NOT a cause for concern. However, if the symbol appears often, we recommend you seek medical advice. Please note that the device does not replace a cardiac examination, but serves to detect pulse irregularities at an early stage. 17 ABOUT BLOOD PRESSURE TROUBLESHOOTING Why my blood pressure is varies even in one day?
1. Individual blood pressure varies every in one day, it also affected by the way you tie your cuff and the your measurement position, so please take the measurement at the same condition. 2.The varies of the pressure is greater if the person take medicine. 3.Waiting at least 4-5 minutes for another measurement. Why the blood pressure I get from the hospital is different from home?
The blood pressure is different even during 24 hour because of the weather,emo tion, exerc ise etc, specially the white coat in hospital which makes the results are higher than the ones at home. If the result is the same if mea s uring on the right wrist?
It is ok for both wrists, but there will be some different results for different person, so suggest you measure the same wrist every time. 18 This section includes a list of error messages and frequently asked questions for problems you may encounter with your blood pressure monitor.
