Things to note
- Please use high-quality alkaline batteries and avoid ordinary batteries with short battery life and leakage of electrolyte.
- Non-professionals should not open or repair without authorization to avoid damaging precision electronic components.
- When installing the transmitter battery, do not press the button without closing the cover to prevent excessive force and damage to the button shell.
- Avoid installing the button on metal objects (like iron doors, stainless steel doors). It is recommended to keep the ringer away from routers and large electrical appliances to prevent signal interference.

Installation method
Music selection
Changan matching
Volume adjustment: Long press to clear code
- Plug the host receiver into a socket. Test if it rings by taking out the buttons.
- Place the doorbell button at a suitable position on the door. Choose a clean surface. If the door is metal, it is recommended to install it on the wall nearby. Close the door and press the button to test. It can be installed after normal use.
- Use the provided double-sided tape. Stick it onto the back of the doorbell button. Peel off the backing and attach the button to the tested position (ensure the surface is clean). After attaching, press and hold for 30 seconds before releasing to ensure a firm bond.

- Step 2: Shows the battery and the cover separated from the main unit.
- Step 3: Depicts the unit reassembled with the battery correctly installed.
Troubleshooting
- The doorbell doesn't ring:
- a. Verify the receiver is properly plugged in and the socket has power.
- b. To confirm successful pairing, try clearing the code and re-pairing the devices.
- c. Check the button battery's charge level and replace it if necessary.
- Short transmission distance:
- a. Metal objects (e.g., iron doors, frames) and other radio signals can reduce transmission range. Avoid installing the transmitter and receiver near metal objects, routers, or similar devices.
