Barometer
The weather station indicates the current
air pressure and charts air pressure fluc-
tuations to create a weather forecast.

The weather station saves the measured air pressure from the last
24 hours. These values are polled as follows:
1. Press
Mode until ▼ is found in the barometer area.

The current air pressure is displayed again approx. 10 seconds
after the last push of the button.
Selecting air pressure unit
The air pressure can either be displayed in mb/hPa or in inHg. The
unit is set with the slider switch (mb/hPa / inHg) on the back of the
radio weather station.
Setting altitude
The altitude is used for calculation of the relative air pressure at seal
level as compared to the absolute air pressure at the installation
site. This relative value is an important reference value for correctly
interpreting weather reports which are based on the relative air
pressure, for example.
The altitude of your city (which could be obtained from a topo-
graphical or trail map, for example) is set as follows:
1. Press Mode until ▼ is found in the barometer area.
2. Press and hold Mode until the current set altitude is displayed.
3. Set the altitude in increments of 10 metres with Set (-100 to
2,500 m).
