how can you change so setting so other door bell dont make yours ring

To change the security transmission code unplug the chime and open the cases to locate the jumpers.(small black plastic pieces). The chime and push button eachhave eight different jumper locations. Jumper positions 1 through 7 are used for setting the code. To change the code, remove a jumper from the same location on both the push button and the chime or move a jumper on the push button from one location to another. Move the matching jumper on the chime to match the new location in the push button. Make sure code positions 1 through 7 are exactly the same on the chime and the push button.

inside the doorbell & button are 3 jumpers. change the settings on one and then the other so doorbell & button are the same
