Connect your circuit: coin battery + sound trigger + wire + bargraph + wire + bargraph. Make sure the coin battery is fully charged so that it lasts the maximum amount of time. You may also want to adjust the sensitivity of the sound trigger [with the little purple screwdriver] so that the collar reacts to a certain volume level.
Place Hook & Loop Shoes on the bottom of the Bits [the Bit feet!] and lock your circuit together.
Open the collar and lay it out straight. Place the circuit on the collar and mark where all the Bit Shoes are.
Use a needle and thread to sew velcro strips down to the places where you marked on the collar. A velcro strip [loop-side] is included when you buy Hook & Loop Shoes.
Now, stick your circuit to the collar and place it on your pup.
