PROTECTED PROGRAMMING

If the memory is "closed", the introduction of further remote control codes can only take place after the memory has been "opened" with one of the codes for the keys programmed in the receiver.

OPENING THE MEMORY AND PROGRAMMING A NEW REMOTE CONTROL

Opening the memory

The memory should be opened by following the operations listed below, carrying them out in quick succession:

  1. press the button (5) on the receiver for about 2 seconds; the LED (4) will flash as long as the button is pressed;
  2. release the button; after about 2 seconds the LED will flash briefly indicating that it is possible to introduce the first figure of the password;
  3. press the button (5) on the receiver as many times as indicated by the first digit of the password (if for example the password is 5.2.0.3., press it 5 times). You should notice that the LED (4) comes on briefly each time the button is pressed to give a visual confirmation;
  4. about 2 seconds after the button is pressed for the last time (the fifth in the example), the LED will emit another flash to request the input of the next figure;
  5. proceed from point 3 and enter all four digits (if the figure is "0", then do not press, but wait for the request for the next figure);
  6. if the password has been correctly entered (memory opened), the LED will start to flash (for about 10 seconds); if, on the other hand, it comes on constantly (for around 10 seconds) then the cycle must be repeated from point 1, because the password has not been recognized.

Programming a new remote control

  1. Whilst the LED (4) is flashing press the button (5) and keep it pressed, the LED (4) should continue to flash;
  2. press the button (3) for the new remote control until the green LED (4) in the receiver comes on constantly.
  3. then re-release the button (3) for the transmitter when the LED (4) in the receiver comes on constantly;
  4. then release the button (5) in the receiver at the end of the programming cycle.

If the procedure has been carried out correctly the LED in the receiver will flash n times (where n is the number of the "country code" selected) confirming that the code has been programmed in both the receiver and the control unit; if this is not the case, the LED will come on CONSTANTLY for 5 seconds; at this point it will be necessary to repeat all the operations starting from point 1 of the programming.

After programming the new remote control, the memory will return to the "closed" state.
