Carefully remove all components from the packaging. Verify that all items listed in the "Package Contents" section are present and undamaged.
2. Installing the Transmitter (Push Button)
The transmitter is powered by a pre-installed 12V 23A alkaline battery. Ensure the battery's insulating strip is removed if present.
- Choose a Location: Select a flat, vertical surface near your door. Ensure the surface is clean and dry.
- Mounting Options:
- Adhesive Tape (Recommended for smooth surfaces): Peel off one side of the double-sided adhesive tape and attach it to the back of the transmitter. Peel off the other side and firmly press the transmitter onto the desired location for at least 30 seconds.
- Screws (Recommended for uneven surfaces or enhanced security): Open the back cover of the transmitter. Mark the positions for the screw holes on the wall. Drill pilot holes if necessary and insert wall anchors. Secure the transmitter's back cover to the wall using the provided screws. Reattach the front cover.
3. Installing the Receivers (Plug-in Chimes)
- Plug each receiver into a standard electrical outlet in your desired locations within your home, office, or classroom.
- Ensure the outlets are easily accessible and not obstructed.

Operating Instructions
1. Pairing (If necessary)
The transmitter and receivers are pre-paired at the factory. If they do not ring when the push button is pressed, or if you wish to add more transmitters/receivers, follow these steps:
- Plug the receiver into an outlet.
- Press and hold the Volume button on the receiver for 5 seconds until you hear a "ding" sound and the LED indicator flashes rapidly. This indicates the receiver is in pairing mode.
- Immediately press the transmitter (push button) once.
- You will hear the selected chime, confirming successful pairing.
- If pairing fails, repeat the steps. Pairing mode lasts for approximately 5 seconds.
2. Changing Melodies
Each receiver can have a different melody assigned.
- Press the "Forward" or "Backward" button on the side of the receiver to cycle through the 58 available melodies.
- Once you hear a melody you like, stop pressing the buttons. The receiver will automatically save this melody.
- To assign this melody to a specific transmitter, follow the pairing steps above while the desired melody is playing.

3. Adjusting Volume
The receiver has 5 adjustable volume levels, including a mute mode.
- Press the "Volume" button on the side of the receiver repeatedly to cycle through the volume levels.
- The LED indicator will flash to confirm the volume change.
- The mute mode (0 dB) is indicated by no sound and only the LED flashing when the doorbell is pressed.
4. Mute Mode
To activate mute mode, press the "Volume" button until the sound is off. In this mode, the receiver's LED indicator will still flash when the doorbell is pressed, providing a visual alert without sound.

Maintenance
1. Cleaning
Wipe the transmitter and receivers with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these may damage the surface or internal components.
2. Battery Replacement (Transmitter)
The transmitter uses a 12V 23A alkaline battery. When the LED indicator on the transmitter no longer lights up when pressed, or the range decreases significantly, it's time to replace the battery.
- Carefully open the back cover of the transmitter.
- Remove the old battery and dispose of it properly according to local regulations.
- Insert a new 12V 23A alkaline battery, ensuring the correct polarity (+/-).
- Close the back cover securely.
