Sixth Step: Use the right batteries for the dog collar.
You should use the batteries recommended by the maker. Place the batteries into the battery compartment of the collar.
Seventh Step: Find out if the system is functioning well.
The underground fence wires must work along with the collar. To find out that both of them are working well, try bringing the collar close to the wires and see if you hear a beeping sound right after. However, if you do not get to hear a beeping sound, this means you need to adjust the boundary setting again until you can hear a beeping sound.
Eight Step: Build a trench.
After finding out that the system is okay, you can now start digging to build a trench. It should not be over three inches deep and should be just enough to accommodate the underground fence wires. After placing the wires, the trench should be covered with the same soil.
Ninth Step: Mark the underground fences.
It is best to set some markers on the boundary line. The markers should be set around five to ten feet apart, depending on the size of the underground fences. Those markers will help the dog remember the boundary line. Once the dog becomes so familiar with the boundary line, you do not need to use the markers anymore.
