A High Noise warning when using an Active Extension is triggered when there is large interference on the 2.4GHz channel which is being used, this can come from common things such as TV cameras, drones, wireless microphones, bluetooth or even public Wi-Fi hotspots. It may also be that the noise warning has been triggered by a Loop Box and so it is important to check your whole surrounding area.

Our 2.4GHz channels can be used alongside other devices on the same frequency, but if these are too strong or transmitting large bursts of data then it can interfere with the detections, with V2 Transponders the interference has been reduced by introducing a secondary backup frequency on all channels.

If possible you should remove the source of the 2.4GHz interference or move it away from your systems, if this is not possible then the channel scanner will show you the best channel to use in your current setup. If you do change channels on your Active Extension then don't forget to also change your Loop boxes and you may also need to change your automatic timing point selection in race result 11.
