10. Atmospheric pressure
10.1 Weather forecast symbols
• There are 5 different weather symbols (sunny, slightly cloudy, cloudy, rainy, heavy rain) and 3 different symbols
for the trend of atmospheric pressure (increasing, steady, decreasing). A snow crystal is shown if rain is forecast-
ed and the outdoor temperature is under 0°C.
• The weather forecast relates to a range of 12 to 24 hours and indicates only a general weather trend. For example,
if the current weather is cloudy and the rain icon is displayed, it does not mean the product is faulty because it is
not raining. It simply means that the air pressure has dropped and the weather is expected to get worse but not
necessarily rainy.

• Press the Relative/Absolute button to select Absolute ("Abs") or Relative ("Rel") pressure display.
• Absolute pressure is the actual atmospheric pressure measured by the main unit.
• The relative atmospheric pressure is referred to the sea level's pressure and has to be adjusted first to your local
altitude. Ask for the current relative atmospheric pressure of your home area (local weather service, www). Hold
the Relative/Absolute button for 3 seconds. Press MAX/MIN/– or °C/°F/+ button to adjust the respective value.
Confirm the setting with the Relative/Absolute button.
• Press the HISTORY/WEATHER button to view the past 12 hours barometric pressure history. The hour is indicated
on the display (0, -1, -2...-12).
• Press and hold the °C/°F/+ button for three seconds to select inHg or mb / hPa as the unit for barometric
pressure.
10.3 Development of atmospheric pressure
