NOTE
10. The default relative atmospheric pressure value is 1013 mb/hPa (29.91 inHg), which refers to the
average atmospheric pressure.
11. When you change the relative atmospheric pressure value, the weather indicators will change
along with it.
12. The built-in barometer can notice the environmental absolute atmospheric pressure changes.
Based on the data collected, it can predict the weather conditions in the forthcoming 12 hours.
Therefore, the weather indicators will change according to the detected absolute atmospheric
pressure after you operate the clock for 1 hour.
13. The relative atmospheric pressure is based on the sea level, but it will change with the absolute at-
mospheric pressure changes after operating the clock for 1 hour.
