Solution: To eliminate EMI try the following methods:

1.Move the sensor or the sensor cable away from the EMI source or move the source of the EMI away from the sensor or the cable.

2.Connect the Sensor’s GND terminal to true earth ground (if this isn’t feasible use the main system unit’s GND terminal).

3.– Optical Feedback Loop

If you have an IR sensor in the same room as a flasher, and you have some low-level noise or interference, an optical feedback loop can occur which will interfere with proper operation. Symptoms can include: poor range, intermittent operation or no operation.

Solution: You can eliminate optical feedback by covering all flashers with the supplied IR blocking covers.

There are many methods for reducing interference. Which solution is best for you depends on your situation. If you require further assistance contact Niles Technical Support at 1-800-289-4434.
