  • How to Match Collars to Your Dogtra Expandable System

    1. Turn the transmitter on by pushing the ON/OFF Button located on the right side (not all transmitters have an On/Off button).

    2. Set the Intensity Selection Dial to "0".

    3. Set the Toggle in the UP position to synch the BLACK (Dog 1) collar (GREEN on T&B systems), or DOWN to synch the ORANGE (Dog 2) collar.

    4. Place the red dot on the back of the transmitter to the red dot on the collar/receiver. Hold the two red dots together for about 5 seconds or more. Release them when the green LED blinks rapidly on the collar/receiver.

    5. Within 5 seconds after taking the two red dots apart, hold down the two buttons simultaneously on the side of the transmitter for 3 seconds or until the rapid green blink resumes to a slower-paced green blink. The LED indicator light will start to blink once every 4 seconds after staying lit green for about a second. Now the coding is completed.
