3.3. Pairing (If Necessary)
The transmitter and receivers are typically pre-paired at the factory. If they do not ring when the button is pressed, follow these steps to pair them:
- Press and hold the volume button on the receiver for approximately 5 seconds until it emits a short chime and the RGB light flashes. This indicates it is in pairing mode.
- Immediately press the doorbell transmitter button. The receiver will chime again, confirming successful pairing.
- Repeat for the second receiver if applicable.
4. Operating Instructions
4.1. Adjusting Volume
The receiver offers 5 levels of adjustable volume, from 0 dB (silent) to 110 dB. Press the Volume button on the side of the receiver repeatedly to cycle through the volume levels until your desired setting is reached.

4.2. Changing Melodies
There are 60 classic melodies to choose from. Press the Song Selection button (usually indicated by a music note icon) on the side of the receiver to cycle through the available melodies. The receiver will play each melody as you press the button.
4.3. RGB Flashing Lights and Silent Mode
When the doorbell receives a signal, the RGB lights on the receiver will flash. This feature can be deactivated if preferred. To select the mode (sound + light, light only, or sound only), press and hold the Song Selection button for three seconds. In silent mode (light only), the RGB lights will flash, providing a visual alert, which is particularly useful for the hearing impaired.
