*11: STORM = ≥ 88 km/h (≥ 55 mph)
STRONG = 42-87 km/h (26-54 mph)
MODERATE = 14-41 km/h (9-25 mph)

2. temperature according to the indication shown underneath 1 (*13)
3. effect of Wind chill and Heat index on Feels like temperature
*12:
Feels like: temperature compensated with the wind chill or heat index
Wind chill: combination of the measured temperature and wind speed
Heat index: combination of the measured temperature and air humidity
Dew point temperature, outside: the temperature at which water vapour is converted into water (mist,
dew or frost). This temperature depends on the outdoor temperature and the humidity.
You can switch between these indications by briefly pressing the
*13: At HEAT INDEX:
< 27°C (display 'LO')
27°C – 32°C (80°F – 90°F)
33°C – 40°C (91°F – 105°F) be careful (risk of dehydration due to heat)
41°C – 54°C (106°F – 129°F) danger (increased risk of exhaustion due to heat)
