Setting the handset and receiver code.
The receiver has to learn the handset code:
Press and hold the receiver's reset button until you hear two (2) beeps.
After the second, longer beep, release the reset button. Within the 20 seconds press the ( small flame / down ) button on the handset. Two (2) short beeps confirm the code is set. If you hear one long beep, this indicates the code learning sequence has failed or the wiring is incorrect.
