Operating Instructions
Pairing the Transmitter and Receiver:
Your doorbell system should be pre-paired from the factory. If re-pairing is needed or if you add additional transmitters/receivers:
- Ensure the receiver is powered on (either by batteries or USB).
- Press and hold the volume button on the receiver for approximately 5 seconds until you hear a short chime and the LED indicator flashes. This indicates it is in pairing mode.
- Within 10 seconds, press the push button on the transmitter. The receiver will chime, confirming successful pairing.
- If pairing fails, repeat the steps.
Melody Selection:
To change the melody:
- Press the 'Melody' button (often indicated by a music note icon) on the receiver to cycle through the 38 available tunes.
- Once you hear your desired melody, stop pressing the button. The selected melody will be saved.
Volume Adjustment:
To adjust the volume:
- Press the 'Volume' button on the receiver to cycle through the 4 available volume levels (0dB to 90dB).
- Select the volume level that best suits your environment.
LED Indicator:
When the push button is pressed, the LED indicator on both the transmitter and receiver will flash, providing a visual alert in addition to the audible chime.

Maintenance
Battery Replacement:
- Transmitter (Push Button): The transmitter uses a CR2032 lithium battery. When the LED on the push button no longer lights up or the range decreases significantly, it's time to replace the battery. Carefully open the transmitter casing (usually by prying it open with a small screwdriver) and replace the CR2032 battery, ensuring correct polarity.
- Receiver (Chime Unit): The receiver uses 3 AAA batteries. If the chime volume becomes low or the unit stops working, replace the AAA batteries in the battery compartment, ensuring correct polarity.
Cleaning:
Wipe the doorbell units with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the surface or internal components. Ensure the push button's seal remains intact for weather resistance.
