PRECAUTIONS FOR PROPER USE
Distance adjustment
•For
•Turn the distance adjuster gradually and lightly with the attached adjusting screwdriver. Turning with excessive strength will cause damage to the adjuster.

| |
| Remove the object. Continue turning the adjuster |

| clockwise until the sensor enters the detecting |
| |
| state again. Then turn the distance adjuster back |
| |
| a little untill the sensor returns to the |

| |
| If the sensor does not go into the detecting state |
| |
| even if the adjuster is turned fully clockwise, point b |
