6. Switch on the power to the Controller.
The green STATUS LED should now be flashing twice as fast
as normal.

Code flat against the left hand side of the RF module, either
above it or below it, and move the card or tag around in
contact with the RF module until the STATUS LED stops
flashing and glows steadily.
The Controller has now learnt its Distributor Code.
8. Remove the power to the Controller.
9. Move the LEARN jumper back to its “down” position, or just
remove it completely.
10. Install the required modules in the Controller and set up the
Controller as described in the rest of this chapter.
The Controller can only learn the Distributor Code once -
you cannot change it once learned.
