*4: Feels like: temperature index is the outdoor temperature most people actually experience
Heat index: combination of the measured temperature and humidity Dew point: the temperature at
which water vapours are transformed into water (fog, dew or frost). This temperature depends on the
outdoor temperature, humidity and air pressure.
Wind chill: combination of the measured outdoor temperature and the wind speed You switch between
these indications by briefly pressing the "INDEX" button.
*5: At HEAT INDEX:
< 27°C (display 'LO')
27°C - 32°C (80°F - 90°F)
