5.2 Load teach phase
At the first switch-on, the load teach phase is launched. During this
phase, the load will switch on, switch off, dim and sometimes flash.
The LED (Channel 1 and Channel 2 push-buttons) associated with the
channel flashes alternately in magenta during the teach phase.
The teach phase lasts approximately 30 seconds. It is complete when
the push-button LED lights up.
Caution:
Following a power failure, the teach phase will be launched after
pressing a switch-on command (if automatic mode has been
selected).
