8. Adding or Replacing Push Buttons
You can use up to 4 push buttons with the same chime unit. If you
want to use a new push button, you need to make sure that the
chime unit recognises the code of the new push button. Proceed as
follows:
1. Install the battery in the push button.
2. Press the coding button [1] on the chime unit.
3. Press the push button.
If the code is set correctly, the chime unit will produce a chime.
4. You can now install the push button in its desired location.
9. Troubleshooting
• When the sound becomes weak, replace the batteries of the chime
unit (see §6).
• If pushing the push button does not produce a chime:
o Check if the chime unit is located within the specified range
(max. 60 m in open field). If not, bring it closer to the push
button.
o Check if chime unit and doorbell push button are not
surrounded by metal or near a strong magnetic field. In these
cases, move the chime unit and/or doorbell push button to a
more suitable location.
o Replace the push button battery (see §6).
o Create a new code between chime unit and push button
(see §8).
