Linking key can be used as a simple way to link receivers to a transmitter without the need to initiate the linking process on the transmitter. This allows the user to just enter the code into the receiver and it will be linked to the transmitter with the same code.
Note: The transmitter must have a linking key set to allow for this.
Note: Receivers can still be linked the traditional way when linking key is used by the transmitter.
Linking key is also a handy way to clone transmitters on transmitters that support this. By entering an 8 digit linking key code in two, or more, transmitters they will act as if they were the same transmitter.
This allows to have transmitters in separate physical locations and move linked receivers between the locations without the need to re-link the receivers.
