CT-1A – CT-1AR CODE SELF-LEARNING
In the self-learning phase, all controls are inhibited.
To enter the self-learning phase, the door must be in the closed status (with G.O.
indicator off). The led indicating all self-learning data is connected to the G.O. Indicator.
During programming, the G.O. indicator flashes in the same way as the indicator led,
and then returns to its original function on completion of the programming phase.

CODE DELETION
When the control unit is powered up, the microprocessor performs an
internal test and the indicator led emits two slow flashes and two fast
flashes to indicate that it is ready for the next phases.
The integrated memory can be reset on start-up of the control unit by
pressing and holding the self-learning pushbutton for 10 seconds. At the
end of this phase, the self-learning indicator led remains lit for 5 sec. To
indicate successful reset. On approach to the end of the 10 second
interval, the indicator led flashes more quickly to indicate that this important
and delicate operation is about to be completed.
When pushbutton P is pressed briefly, the indicator led emits a series of
slow flashes for 10 sec.
to indicate entry in the self-learning phase. During this interval, if the radio
control is pressed, the code is acquired with the radio control channel on
which it was transmitted (1°, 2°, 3°, or 4°). If the code is memorised
correctly, the led remains lit for 2 sec. After the first memorisation
command, the led flashes for a further 6 sec. on standby for a new
memorisation command; if this is performed, it continues to flash for
6 sec.; otherwise it exits the programming phase. If a previously memorised
code is entered during this phase, the led flashes quickly to indicate that
the code has already been memorised. During the self-learning phase,
there is also the option to memorise several codes also on different
channels (e.g. an initial user memorises the code "x" from channel 1°,
and a second user memorises the code "y" from channel 2°).
Press pushbutton P four times and the led emits a series of slow double
flashes for 10 sec. To indicate entry in the code deletion phase. In this
interval, if the radio control is pressed, the code can be deleted from the
memory. Unlike the entry phase, the unit exits the deletion phase as
soon as the code is transmitted. To delete another code, the same
procedure must be repeated from the start. If deletion is successful, the
led remains lit for 2 sec.
