VII. How to adjust the sensitivity and volume

Since people have different expectations for the driver fatigue alarm,

the sensitivity is adjustable, this prevents many false alarms. We have

4 levels of sensitivity for your choosing. The recommended level is

medium sensitivity.



Max sensitivity: levers 1 & 2 both in the down position, testing

level



High sensitivity: lever 1 up, lever 2 down, this has some tolerance

for looking around.



Medium sensitivity: lever 1 down, lever 2 up, typical use.



Low sensitivity: levers 1 & 2 both in the up position, only detects a

trance or sleep.

Each of the 4 level's minimum alarming time is 2 seconds, the

difference is the reaction time for the eye's closing or looking around.



Max Audio: levers 3 & 4 both in the down position



Medium Audio: lever 3 up, lever 4 down



Low Audio: lever 3 down, lever 4 up



No Audio: levers 3 & 4 both in the up position
