Operating Instructions
Pairing Receivers with Transmitters
To set a separate sound for each receiver or pair a new transmitter, follow these steps:
- Plug the receiver into an electrical outlet.
- Briefly press the "Music" button on the receiver to select your desired ringtone.
- Press and hold the volume button on the receiver for approximately 5-7 seconds until the blue light flashes. This indicates the receiver is in pairing mode. Note: The receiver will exit pairing mode automatically if no signal is received from the transmitter within 5 seconds.
- Immediately press the transmitter button. You will hear the selected ringtone, confirming successful pairing.
- Press the transmitter again for a final verification. If the melody plays, the pairing process is complete.
To set a different sound for a receiver triggered by another transmitter, simply select a new song on that receiver and repeat steps 1-4 with the new transmitter.

Reset/Clear Receiver Pairing Memory
To reset or clear the pairing memory of a receiver:
- Plug the receiver into an electrical outlet.
- Press and hold the "Music" button on the receiver for approximately 10 seconds until you hear a "ding" sound and the light flashes. This indicates that the receiver's memory has been reset/cleared.
Volume Adjustment and Chime Selection
The receiver offers multiple volume levels and 58 different chimes to choose from. Use the dedicated volume button to cycle through volume levels and the music button to select your preferred chime.
