ADJUSTMENTS

Sensor Adjustment

Remove the wall plate. Remove the button cap by firmly squeezing together the 

top sides of the button assembly. Gently pull it away from the unit. 
When the adjustments are completed, replace the button cap by inserting its 

hinges into the tabs on the main unit and then squeeze the top of the button 

while pressing it into the unit. Reinstall the cover plate.

Light Level Adjustment

The light level can be set with loads 

ON

 or 

OFF

. To enable light level control and 

set the threshold: 

1.  Make sure the room is lit appropriately.
2.  Put the sensor into TEST mode. You have 5 minutes to complete the 

procedure.

3.  Press and hold the ON/OFF button for 

3

 seconds, until you hear a beep.

4.  Step away from the sensor. After 25 seconds a beep sounds, indicating that 

the threshold level is set. This threshold is retained, even if power is lost, until 

it is re-set or disabled. 

To disable light level control, press and hold the ON/OFF button for 

7

 seconds, 

until a double beep tone sounds.

Reset to Default

Use the DIP Switch Settings tables on the previous page to return features 

to factory settings. To reset the DW press and hold the ON/OFF button for 

10

 

seconds, until a triple beep sounds. This resets the sensor and disables light 

level control (the brightest ambient light will not hold the light OFF).

Service Mode

To enter service mode set the ultrasonic trimpot to MIN (Fully counter-clockwise).
