Note: Most installations will not require you to change any of the jumpers
on your doorbell.
The transmitter and chime communicate by using a code that can be changed by
removing and/or adding jumpers on both the transmitter and chime. The code is
factory set; however, there are 128 selectable codes that allow you to expand your
system and prevent outside interference. Another wireless doorbell system or other
wireless products may cause interference and the system may not function properly.
Follow the instructions below for setting a new code.
1. Disconnect the power to the transmitter and chime.
2. Open the cases and locate the jumpers on both the transmitter and chime (See
illustration).
3. The transmitter and chime both have eight different jumper locations. The jumper
positions 1 through 7 are used for setting the code.
4. To change the code, add and/or remove jumpers as needed. There are 128 dif-
ferent combinations. It is recommended to only change one jumper at a time and
then check to see if system is functioning properly. Note: Jumpers in positions 1
through 7 must be exactly the same for both the transmitter and chime for this
system to function.
