1.Sensitivity setting:

At the first experiences and tests on the fatigue monitor system MR688, some may wish to immediately receive alert once their eyes close, which would prove to them the system has a high sensitivity. In fact, after using for a certain time, this may interrupt them because some are non-sleeping warnings caused by unintended blinks or fake sleep, and they prefer an alarm only for real sleepy condition. So we set up 2 sensitivity levels for customers to adjust conveniently as per their requirements. For each level the anti fatigue warning system MR688 can quickly and accurately detect the real drowsy and absentminded conditions. The only difference lies in the alert response time.



Please see above pictures, the toggle switch is 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), it takes about 2-3seconds to alarm when detecting the driver's sleep or distraction.

1B: DIP1=ON(pull up), for normal sensitivity, it takes a little bit more time to make an alarm when driver's drowsiness or inattention occurs, about 4-5 seconds.



According to different requirements of the operators, the volume can be set by adjusting the DIP switch 4(DIP-4)

4A:DIP4=OFF(pull down), high volume.

4B:DIP4=ON(pull up), low volume.

Note: For DIP2 and DIP3, it doesn't have function here, it is suitable for the MR688 commercial professional version(with speed detection module)
