Then, if there are more buttons for recording information than the
original remote, press 'Next' and the application will ask you to press the
corresponding button. If all of the original remote's buttons have been
read, press 'Finish readings'.
When you press 'Next', the application will ask you to press the buttons
on the original remote in turn.
Once all of the readings have been taken and you have pressed 'Finish
readings,' the application will display the message to change all the
positions on the original remote. This action is required so that the
duplicate remote knows which position to start from and it completes the
original remote switch pattern. It searches by comparing previous with
later readings.
If the original remote has no switches and the copy has been made using
this mode, you can press 'Original has no switches.'
Once you have modified all the positions, press 'Next'. Then repeat the
same readings of the original remote, but this time with the switches
changed. Once the same number of readings have been repeated,
press 'Next' and the following message will appear indicating that the
readings have been carried out.
Press 'Next' to see the following screen, where you must select the
button(s) to record the code read.
When you press 'Next' the application will ask you to select the buttons
where you want to save the code read. It will then ask you to choose the
buttons for each code read.
Once all of the buttons have been selected, when you press 'Next' the
application will show the position in which you have to place the switches
on the original remote and the position in which you have to place the
switches on the duplicate remote, where relevant.
Duplication is now finished.
