*Placeswhereexcessiveforceorvibrationisappliedtothemotionsensor.
*Placeswherestaticelectricityorelectromagneticwavesmaygenerate.
*Placeswhereisinterferenceforinfraredlightsuchasglassesormistinadetectingarea.
*Placeswherethelensformotionsensorisexposedinhightemperatureandhumidityforalongtime.
*Placeswhereuidandcorrosivegasexist.
*Placeswheredirectlightssuchassunlightorheadlighta󰀨ectthemotionsensor.
*Placeswherehotairfromaheater,etc.a󰀨ectsdirectlythemotionsensor.
*Placeswheretheairowreturnstothemotionsensorbyhittingobstaclessuchasshelf,locker,etc.

*Placeswhereweathera󰀨ectsdirectlythesurfaceofthemotionsensor.
*Placeswherethelenssurfacemaysmudgeorbedamagedsuchasadustyenvironment.
Payattentionthatthedetectingfunctionwillbedecreasedifthelensformotionsensorsmudges.
Inthiscase,wipeo󰀨smudgesbyacottonswabsoakedalcohol(Isopropylalcoholisrecommended.)
orasoftcloth.
(Whenwipingo󰀨smudgesonthelensformotionsensor,donotapplyexcessiveforce.
Ifexcessiveforceisapplied,theresinlensmaybedamagedsothatmaycausemalfunctionssuchas
misdetectionorundetectableofthemotion.)
