Microwave Sensitivity: Microwave Sensitivity Adjustment is set to the fully clockwise position at the factory for maximum sensitivity (range). The installation in a small room, it may be desirable to reduce microwave sensitivity. Turn the Microwave Sensitivity Adjustment (Fig. 2) counter-clockwise to reduce sensitivity. Setting the adjustment to minimum (fully counter-clockwise) reduces sensitivity to approximately one-third of its maximum value.


| Trouble | Likely Causes | Remedy | 
| Unit does not power up. | No or low input power. Input power polarity reversed.  |  			Apply proper input voltage. Correct wiring polarity. | 
| Alarm LED does not light. | LED jumper is set to “LED OFF”. Incorrect sensor mounting height or aiming. Pulse count setting incorrect for protection area .  |  			Set LED jumper to“LED ENABLED”. Alter the mounting height or aim. Set pulse count jumper to suit the detection requirements.  |  		
| Alarm LED / Relaytriggers without movement in the protection area. | Animals / rodents in protection area. Heating or air conditioning outlets in sensor view. If using the optional animal immune lens: Pet access to furniture or room fixture in view of the detector.  |  			Block access of animals / rodents. Re-aim sensor. Ensure that pets can not climb up onto furniture / fixtures in protection area.  |  		
| An alarm is indicated at the LED but not at the alarm output. | Incorrect wiring at the alarm output terminals. Lightning damage.  |  			Correct the wiring fault. Replace sensor.  |  		
| Alarm LED on constantly, no fault in protected area or wiring . | Defective unit. | Replace sensor. | 
| Unit continues to operate after input power has been disconnected. | The wire to the power input was disconnected, the “+” is still connected. The power is finding a return path through the Alarm Output protection device and alarm wiring. | Disconnect wire from the “+” power input. |
