The LED lights are flashing yellow (once every 3 seconds).
(This means something is too close to the sensor box lens or that the system has detected an
electronic fault.)
1. Check if there is an obstruction in front of the lens (closer than 15cm) or if there is debris on the sensor box lens.
Remove the obstruction and/or clean lens. If this does not stop the yellow flashing then see below step.
2. Pull the power cord from the sensor box then plug power back in. If at power up there is a series of descending
pitch tones instead of a chirp from the audible alert and the yellow flashing is still present, then there is an
electronic fault in the sensor box.
