Setup and Installation
1. Install Transmitter (Doorbell Button)
- Choose a Location: Select a flat, vertical surface near your door. Ensure the surface is clean and dry.
- Method A: Adhesive Tape Installation
- Peel off one side of the double-sided adhesive tape and attach it to the back of the doorbell button.
- Peel off the other side of the tape and firmly press the doorbell button onto the desired location for at least 30 seconds.
- Method B: Screw Installation

- Mark the positions for drilling holes using the back cover as a template.
- Drill two holes, insert the wall anchors, and then secure the back cover with the provided screws.
- Snap the doorbell button onto the secured back cover.
- Battery Installation: Ensure the alkaline battery is correctly inserted into the transmitter with the correct polarity.
2. Install Receiver (Plug-in Unit)
- Plug the receiver into any standard electrical outlet within range of your doorbell button.
- For optimal performance, avoid plugging the receiver into outlets near large metal objects or other electronic devices that may cause interference.
3. Pairing (Synchronization)
Your doorbell kit is typically pre-paired at the factory. If the button and receiver do not communicate, follow these steps to pair them:
- Plug the receiver into an electrical outlet.
- Press and hold the volume button on the receiver for 3-5 seconds until the LED indicator flashes and you hear a 'ding' sound, indicating it is in pairing mode.
- Immediately press the doorbell button (transmitter). The receiver will ring, confirming successful pairing.
- If you have multiple buttons, repeat steps 2 and 3 for each additional button.
Operating Instructions
1. Changing Melodies
The receiver offers 55 different melodies. To change the melody:
- Press the 'Melody Selection' button (usually a musical note icon) on the receiver to cycle through the available tunes.
- Once you hear a melody you like, stop pressing the button. The receiver will automatically save this selection.
2. Adjusting Volume
There are 5 adjustable volume levels, from 0dB (silent) to 111dB (maximum). To adjust the volume:
- Press the 'Volume' button (usually a speaker icon) on the receiver to cycle through the volume levels.
- The receiver will indicate the current volume level with a sound or LED flash.
3. LED Flash Indicator and Silent Mode
The receiver features an LED flash indicator, which is particularly useful for individuals with hearing impairments or when the doorbell is in silent mode.
- When the doorbell button is pressed, the receiver will flash its LED light in addition to playing the selected melody.
- To activate silent mode, cycle through the volume levels until the volume reaches 0dB. The LED flash will still activate when the doorbell is pressed, providing a visual alert.
4. Memory Function
The doorbell receiver is equipped with a memory function. It will retain your last set melody and volume level even after a power outage or if it is unplugged and replugged.
