Because of the different understanding to the product, peoples ’ initial expect of purchasing is to
hope the product can be alarmed once their eyes closes. In fact, this may cause some non-sleeping
warning, they may complain too much warning after using several time and prefer to make alarm
only for real sleepy condition. So we set up 2 levels sensitivity to help customers adjusting
conveniently when they use the product. Each level it can quickly detect the real sleepy or
absentminded condition, only the alarming time is different for looking around and normal eyes
closing.
Please see above pictures, the toggle switch located at the back side of the product, it will be pushed
to the OFF position before delivery.
1A: DIP1=OFF(pull down), for testing sensitivity( high sensitivity,
for test use)
1B: DIP1 =ON (pull up), for normal sensitivity. It takes a little bit
more time to make alarming for driver’s looking around.
