Displaying the Forecast
Your console generates a weather forecast based on the barometric reading & trend,
wind speed & direction, rainfall, temperature, humidity, latitude & longitude, and time
of year. Included in the forecast is a prediction of the sky condition (sunny, cloudy, etc.)
and changes in precipitation, temperature, wind direction or wind speed.
Press FORECAST to display the forecast. The forecast ticker message at
the bottom of the screen predicts the weather up to 48 hours in advance.
The forecast is updated once an hour, on the hour. Predictions are made for cloud cover,
temperature trends, the likelihood of precipitation, timing, severity and windy condi-
tions.
Forecast Icons
The forecast icons show the predicted weather for the next 12 hours. If rain and/or
snow is possible but not necessarily likely, the partly cloudy icon along with the rain or
snow icon displays. When both the rain and snow icons display together, a chance of
rain, freezing rain, sleet and/or snow is likely.
Displaying Time & Date or Sunrise & Sunset
Your console shows the sunrise and sunset time in the same place on the screen used by
the current time and date. Press 2ND and then press TIME to toggle the screen between
the current time and date or the sunrise and sunset times for the current day.
Note: See “Screen 4: Time & Date” on page 12 to change the console time and date or to
select a 12- or 24-hour clock.
