EW3122S Upper Arm Blood Pressure Monitor (Silver)

The "DFT" Digital Filter Technology uses a sensor to detect and isolate only the essential pulse oscillation. It helps eliminate other noise factors, leading to quick and reliable measurement capability. This also helps avoid over-tightening of the cuff on the wrist.The monitor lights up if you are moving during a reading, alerting you to the fact that your reading will not proceed unless you stop moving.The Automatic Memory Feature Saves your Readings and allows you to capture 84 readings (42 memory readings x 2 persons) and save them to track the readings over time.The cuff easily folds into the built-in storage case for added convenience. The Color Confirmation System Helps You Understand Your Readings, the monitor uses a 3-color light system to indicate if your reading falls in the Hypertension, Prehypertension or Normal Range: Systolic - Red: Hypertension (over 140),Yellow: Prehypertension (130-139),Green: Normal (under 129). Note: The female connection is for the AC adapter. The pressure cuff plug with the "plastic covering" should be placed into the pressure cuff socket. This socket is a separate connection point on the main unit. The instruction manual should clearly indicate usage.
