Byron DBY-22314 doorbell set with a wall-powered indoor chime (DBY-22312) and a battery powered chime (DBY-22311)

[gkey01]

please find below the results for a Byron DBY-22314 doorbell set with a wall-powered indoor chime (DBY-22312) and a battery powered chime (DBY-22311).

At first use the doorbell should be pressed within 20 seconds to pair with the 2 chimes.
On the inside of the ringer there is a small button to change melodies. I have added 2 files with my results (one for the ringer, the other for the melodies).

In the attachment I have included ringer and chime recordings.
