The lists are accessed by pushing one of two buttons on the front of the buffer. They are then printed out on a small thermal printer attached to the buffer. The default criteria is 3 mounts in 4 hours with each mount having a 2-second or greater duration. The list displays which cows are in heat, total number of mounts, the onset of heat and the best time to breed. Pushing the second button provides a list concerning the working status of all transmitters.
All transmitters send a supervisory signal every hour.
If a certain transmitter is not checking in, the system will alert you to that problem transmitter.
