The frequency set on the EK 6042 is transferred to the transmitter. If the transfer was successful, the status LED of the corresponding receiving channel lights up green - provided that the transmitter is not muted. The radio link is ready for immediate use. If the transfer fails, the message Failure appears on the display panel
