desired at a later date, using the steps outlined in the section for Setting or Changing Pressure and Altitude settings. Changing Pressure and Altitude Parameters The weather station is designed to measure local pressure and calculate the other two parameters based on the Local Pressure. Sea Level Pressure and Altitude are interdependent. If you adjust altitude, it will calculate sea level pressure, if you adjust sea level pressure, it will automatically calculate altitude. You can only adjust one of the two - either sea level barometric pressure or altitude. If you wish to know pressure changes at your specific location (house), the LOCAL barometric pressure should be selected In this case, the local altitude/elevation must be programmed according to GPS readings, Internet, etc. If you wish to know pressure changes in your surrounding metro area, then SEA LEVEL barometric pressure option should be selected. In this case, the SEA LEVEL barometric pressure value can be adjusted according to the local metro area weather information. (Sources - local TV or radio station, etc) During initial power up (within the first 5 - 10 minutes) the weather station will not operate. These parameters can be modified after the display has stabilized Select the Pressure and Weather Forecast window by pressing UP or DOWN arrow button until the pressure and weather forecast icon starts flashing. NOTE: Locate your altitude with a portable GPS receiver or topographical map .Locate barometric pressure at: http://weather.noaa.gov/weather/ccus.html or, alternatively, from local radio or TV weather channels. Changing or Setting Sea Level Pressure • Press SET button until the pressure with the word "SEA LEVEL" is displayed. • Press and hold MEMORY button until the pressure unit is flashing, inHg, mmHg or hPa/mBar • Set the pressure units by pressing the UP or DOWN arrow buttons • Press MEMORY button to confirm your selection • Press and hold SET button until the sea level pressure digits will flash. • Set the sea level pressure by pressing the UP or DOWN buttons to adjust the pressure value. Press and hold UP or DOWN arrow buttons for faster digits advancement • Press SET to confirm your selection. Changing or Setting Altitude • Press SET button until the local altitude value will be displayed • Press and hold MEMORY button until the altitude unit is flashing, Feet or Meters. • Press UP or DOWN arrow buttons to set altitude in feet or meters • Press MEMORY button once to confirm your selection 18
