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
