The transmitter can learn the current code from another one that is placed in close proximity to it. When carrying out this procedure with the 868.3 MHz versions, they should be kept well clear of any GSM 900 mobile phone. The factory reset button, which is on the left of the wiring side of the pcb, can be accessed through the battery compartment.
