Locate the two buttons located on the side of the receiver. The program button is a solid dot and the melody selector button has a musical note symbol next to it.
Hold down the programming button for approximately 3 seconds until you see a solid red LED inside the strobe light lens.
Let go of the programming button–the red LED should stay on.
Simultaneously, hold down the programming and melody selector buttons together for approximately 5 seconds until you hear a short tone sound.
Let go of the buttons. You should now see the red LED flashing rapidly.
A flashing red LED denotes programming mode.
