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.
This applies to the following ERA transmitters (ERA-DSTX, ERA-UTX, ERA-PIR)
-The ERA-DCRX (receiver) has four zone indicator lights that blink when triggered.
-When the battery is low in a transmitter paired to a corresponding zone, the zone indicator LED for that light will blink for 10 minutes when that zone is triggered.
-When the battery is low in a transmitter paired to a corresponding zone, the melody for that zone will play twice (normally the melody will play only one time).
For the ERA-PIR-SPK: when the battery is low, the melody will play twice, instead of once.
