Sensor Range Adjustment 

In the event the IR sensor is giving false reading.  Please do the following 

1.  Open the faucet top cover.

2.  Locate the yellow / blue range adjustment module.  (See picture)

3.  Rotate the module clockwise to decrease the sensing range.  

     Counter clockwise to increase the sensing range.  

4.  Place your hand in front of the sensor to verify the sensing distance.  Repeat the process until desired distance is achieved.  

Tips:  If sensor range is set too close or too far.  Sensor could falsely read nearby object and behave abnormally.  Repeat the above steps to achieve desired result.
