Steps:

• Remove the back cover of the sensor
• Locate the sensitivity knob inside
• Use a small screwdriver to turn the knob

Direction:

• Counter-clockwise → Increases sensitivity
• Clockwise → Decreases sensitivity

Important Caution:
Imagine the screw as a clock face — do not rotate more than 5 minutes' worth at a time (i.e., no more than 30° of rotation per adjustment).

Why small adjustments?

• Prevents over-correction
• Allows you to test the sensor's response between adjustments
• Avoids damaging the internal potentiometer
• Helps you fine-tune to the ideal sensitivity gradually

Tip: After each small adjustment, test in place and check the sensor's behavior before making further changes. If needed, repeat the 5-minute adjustment until optimal sensitivity is reached.
