Figure 5. IS4125 Object Detection Field 
Please note certain ambient light conditions may interfere with the object 
detection mechanism, resulting in false activation of the engine.  To mitigate the 
problem, please try one of the following suggestions: 
1.  Avoid mounting the engine directly facing the ambient light source.  
2.  Avoid mounting the engine facing a light-colored or reflective surface.  
3.  Avoid mounting the engine towards a surface at a distance close to the 
long range (9" – 11") of object detection  
4.  Configure the object detection range to short (4" – 7").
