Things You'll Need
Heath Zenith wireless doorbells are one way to install door bells on your home without having to run electrical wire through the home. The disadvantage to these types of doorbells is that sometimes a frequency from a nearby wireless system can ring your bell. You can program the heath Zenith wireless doorbell to a different frequency. The unit uses dip switches much like older garage door openers. To reprogram the frequency, simply move a dip switch to a different location. Remember though, the dip switches on the push buttons must match those on the chime.
Push in the retaining tab at the bottom of each door bell push button with a flat-head screwdriver. Pull the push buttons off their mounts. Take each push button to the door chime.

Turn off the circuit breaker to the chime junction box. Remove the screws securing the chime to the junction box with the flat-head screwdriver. Pull the chime away from the junction box enough that you can access the dip switches on the back of the chime.
Move one of the dip switches up or down on the door chime. Move the same dip switch to the exact location on the door bell push buttons. Press the door bells to ensure that the dip switches match each other.
Remove the small jumpers over an individual switch, for further programing. The jumpers remove with tweezers. Remove the duplicate jumper on the push button when removing jumpers in the chime.
Place the chime back over the junction box and secure with the retaining screws. Snap the door bell push buttons back into their mounts on the door jamb.
