## **Adjustment Method 1** 

1. Set the pointer of the sensitivity adjuster to the center of its revolution range. 

When the quantity of light reflected from the object is greater than that from the background object, adjust the sensing distance in the following sequence: 

2. Turn the distance adjuster fully counterclockwise to the “S” position. 

   1. Set the pointer of the sensitivity adjuster to the center of its revolution range. 

3. Set the sensing object in position. 

   2. Turn the distance adjuster fully counterclockwise to the “S” position. 

4. Turn the distance adjuster gradually clockwise to a point where both the LIGHT and STABILITY indicators light. Fix the distance adjuster at that point. 

   3. Set the sensing object in position. 

5. Adjust sensitivity.
