15OPERATIONUsing the Weather StationLearning ModeSelf-Calibrating Forecasting uses a unique algorithm to analyze changes inpressure over a time period (called Learning Mode) to determine your altitude.After 14 days, the icon disappears from the display screen. At this point,the self-calibrated pressure is tuned in to your location and the unit is ready forsuperior weather prediction.Weather ForecastAcuRite’s patented Self-Calibrating Forecasting provides your personal forecastof weather conditions for the next 12 to 24 hours by collecting data fromthe sensor in your backyard. It generates a forecast with pinpoint accuracy -personalized for your exact location.Barometric PressureSubtle variations in barometric pressure greatly affect the weather. Thisweather station displays the current pressure with an arrow icon to indicate thedirection the pressure is trending (FALLING, STEADY, or RISING).Lightning DetectionThe lightning sensor detects cloud-to-cloud, cloud-to-ground and intra-cloudlightning. When lightning is detected, the sensor will beep and the strike indicatorwill flash for each of the first 10 strikes. After 10 strikes, the sensor will enter silentmode but will continue to flash. The sensor will stay in silent mode for 2 hours afterthe last lightning detection.The display will automatically show the most recent lightning event (TODAY, WEEK,MONTH, YEAR). The icon appears on the display when lightning is detectedand keeps a running count of lightning strikes detected. The display shows anestimate of the distance to the front of today’s lightning-producing storm.STORMCONDITIONSDEVELOPING(Rain = Flashing)SNOWLIKELYLIGHT RAINLIKELYPARTLYCLOUDY CLEAR SKIESCLOUDYView the complete list of icons at www.AcuRite.com/acurite-icons
