Niles Audio MSU250 TROUBLESHOOTING

TROUBLESHOOTING (CONTINUED)
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 inter-
ference, 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 replacing any IRB1 “flooding flasher” with MF1 or
MF2 MicroFlashers and 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 or
