Set the pointer of the sensitivity adjuster to the center of its revolution range. 2. Turn the distance adjuster fully counterclockwise to the “S” position. 3. Set the sensing object in 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. 5. Adjust sensitivity. Adjustment Method 1 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: 1. Set the pointer of the sensitivity adjuster to the center of its revolution range. 2. Turn the distance adjuster fully counterclockwise to the “S” position. 3. Set the sensing object in 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. 5. Adjust sensitivity.
