6.1 Driver fatigue alert
To help drivers keep track of how tired they might be,
the device comes with a fatigue alert. This takes into
account both physiological and journey related
parameters; for example, it considers the time of day
and the time spent on driving. Furthermore, the divice
will alert you every two hours of driving, to remind you
that fatigue could become an issue.
Besides this alert, there is also a fatigue indicator on the
device's display.With a fatigue rating below 60, the
indicator is green. When the fatigue rating is between 60
and 80, the indicator is yellow and a warning alert sounds.
When the fatigue rating reaches 80, the indicator turns red
and three warning beeps sound.
When you switch on this driver fatigue feature, it's
important that you set correct system time (so it knows at
what time of day you're driving). If you have this feature
switched off, the fatigue rating will not be displayed on the
screen.
