•
FLASHING AMBER
The Detector is receiving a weak signal and is attempting to increase the infrared power output.
•
OFF
The Detector has optimised the infrared power and receiver gain for the current orientation of the
Detector and Prism. This does not mean that the Detector to Prism alignment is at its optimum,
i.e. if the power is too high, a misaligned Detector may be receiving a fringe reflection from another
object.
•
FLICKERING RED/AMBER
This state can occur sometimes. It means that the infrared power is stepping through the optimum
setting.
