1. Set the Intensity Selection Dial to level 0. For dog 1, place the toggle switch in the up position. For dog 2, place the toggle in the down position.
2. Starting with the receiver/collar turned OFF, place the two red dots together for 5 seconds. The LED on the receiver/collar will rapidly blink green when successfully in code setting mode. Once in code setting mode, separate the receiver/collar and the handheld transmitter.
3. While the LED on the receiver/collar is rapidly blinking, press the two side buttons (Low & Medium) simultaneously on the transmitter. The code setting is complete when the LED on the receiver/collar blinks every 5 seconds.
