Here is an example for channel selection (literally):
Press and hold "LEARN" button on the radio receiver switch for about 3 seconds, until the LED flashes, enter channel selection mode; Time of channel-select mode will keep about 15 seconds, now press the button on the transmitter, the receiver switches on the radio flashing LED when channel selection is successful, it is the channel-select state after 15 seconds ended when channel Selection defeated. ...
Furthermore, since the remote control did not work with me, I had written in an initial assessment according to a negative review.
Meanwhile I get a replacement for the returned set, and this time the remote control works.
As well as mapping and function were now install properly, I correct my review and forgive rather than a star - 4 star.
