Step
1. Turn the sensitivity adjuster fully counterclockwise to the
minimum sensitivity position
2. In the light received condition, turn the sensitivity adjust-
er slowly clockwise and confirm the point A where the
sensor enters the "Light" state operation.
3. In the dark condition, turn the sensitivity adjuster further
clockwise until the sensor enters the "Light" state opera-
tion and then bring it back to confirm point B where the
sensor just returns to the "Dark" state operation.
If the sensor does not enter the "Light" state operation
even when the sensitivity adjuster is turned fully clock-
wise, the position is point B.
4. The position at the middle of points A and B is the opti-
mum sensing position.
Note: Use the flathead screwdriver (purchase separately) to turn the adjuster slowly. Turning with excessive
strength will cause damage to the adjuster.
