EN GETTING STARTED INSTALLING AND REPLACING THE BATTERIES 1. Slide off the battery cover. 2. Install the batteries by matching the correct polarity, as shown below. Always use the correct battery type (2 alkaline LR03 AAA-size). 3. Replace the cover. HOW THE BLOOD PRESSURE MONITOR WORKS This product uses the Oscillometric Measuring method to detect your blood pressure. Before every measurement, the unit establishes a "zero pressure" equivalent to the air pressure. Then it starts inflating the wrist cuff to 180mmHg or higher until it senses that it has blocked your blood in the artery. After that, the deflation process starts, during which time the unit detects pressure oscillations generated by beat-to-beat pulsatile, which is used to determine the systolic, mean and diastolic pressure, and also your pulse rate. Any motion during this period will result in an incorrect measurement. After all readings are determined and displayed on the LCD, the measurement is finished and the wrist cuff automatically deflates. NOTE Replace the batteries whenever the weak battery mark shows, the display is dim, or the display does not illuminate when the power is on. Replace all the batteries at the same time - it is dangerous to mix old and new batteries. Contact your local waste disposal authority for instructions on how to dispose of used batteries. Used batteries can be harmful to the environment, and should not be thrown out with household trash. 7
