I followed the simple directions on the pamphlet found on the outside of the box this golden nugget is for those who cant seem to find the instructions thats not a box label so dont toss it

Collar receiver were charged synced per the instructions another golden nugget for those who failed to read the instructions one must sync the collar to the transmitter remote and placed it on

Needless to say i was very pleasantly surprised that a nonshock collar could be so effective and reasonably priced
