Collar emits a brief audible click to let you know the collar is on right and functioning properly
UltraSmart collars alert you to potential problems before it's too late. After charging, UltraSmart collars automatically perform a vital systems check to ensure proper operation of the power and electronic circuits. A green light means all systems are functioning properly and a flashing red light indicates there is a collar problem.
3-way battery indicator. Never run out of battery power again. ReadyTest monitors battery levels in your dog's collar. Green is more than half a charge, yellow means less than half and red means charge the collar at the next opportunity.
