3.2. Learning Additional Transmitters
1. To learn additional transmitters into memory using a master transmitter implies that
at least one transmitter button (that must be a master) is already learnt into memory.
In other words, the channel compartment of interest must not be blank, and the user
must have access to a master button associated with that channel compartment.
2. Press and hold a master button that has functionality on the receiver that needs to be
copied. The receiver LED will flash once per second as per the standard master flash.
The master button must be held for between 10 and 20 seconds. After 10 seconds,
the receiver will provide a long beep to indicate that it has entered the learn mode
window. Releasing the master button within this 10-20 second learn mode window,
will place the receiver in learn mode. The receiver will stay in learn mode, for a
particular channel, for a period of ten seconds, failing any additional button presses.
While in learn mode the LED on the receiver will remain on.
3. Any unlearnt button that is pressed, and held down for a minimum of three seconds,
while in learn mode, will be added to the receiver.
4.
The Status LED will switch off while the unlearnt button is activated within the three
second learning window. This confirms three things:
a. The button transaction is being received by the receiver
b. The button is not learnt into memory. If the button is already learnt into
memory, the LED will not turn off (for the complete learning period) when the
button is pressed (refer to points 6.a and 6.b. below for further clarification)
c. The button learning process is not finalised.
5. Once the three second period has elapsed, the LED will turn on again and the buzzer
will provide a double-beep. This serves as visual and audible confirmation that the
receiver has learnt the button being pressed. (Refer to Appendix A on page 30 for a
description of the LED and buzzer feedback)
6. If the button is already learned into memory when it is pressed, the leading edge of
the transmitter transaction is acknowledged with a short beep.
a. The LED will not switch off for a button that is already learned into memory as a
master.
b. The LED will flash periodically (64ms on/448ms off) if the button is demastered,
and is being held down to remaster it. Following the three second learning
window, the button will be remastered. The LED will switch on again, and the
buzzer will beep once briefly to confirm the successful remastering operation.
7. Any additional remotes learned into memory are also given master privileges.
Hence, every button added to the receiver in this way automatically becomes a
master for functionality associated with the master that placed the receiver in learn
mode.
8. Any button that is pressed while the receiver is in learn mode (whether the button
is already learnt into memory or not) will extend learn mode by an additional 10
seconds from the time the button is released.
9. If no additional buttons are pressed within the 10s learning period, the receiver will
automatically exit learn mode. This exit is signalled by an extended single beep.
The Status LED also switches off and resumes its responsibilities in normal mode.
