Select Pressure and Weather Forecast Window

Press UP or DOWN arrow buttons on the main unit until the weather forecast icon

begins to flash, upper display left

corner.
NOTE: Wait at least 5 - 10 minutes after initial set up to view a pressure or altitude information.

Pressure and Altitude Information
Press SET button once (do not hold it) to alternate between the Sea Level Pressure, Local Pressure and Local Altitude
settings.
The unit should be set to the default settings of: inHg (Inches of Mercury), and 33 feet. These parameters can be changed as
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)
