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.
