Setup and Installation
The AVANTEK CW-21 doorbell offers flexible installation options for the transmitter and simple setup for the receiver.
Receiver Setup
- Plug the receiver into a standard electrical outlet. Ensure it is placed in a central location to maximize wireless range.
- The receiver will power on and be ready for operation.
Transmitter Installation
Before installation, ensure the transmitter's battery is active. The transmitter uses a lithium battery with a maximum lifespan of 3 years. No battery installation is typically required upon initial setup as it comes pre-installed with a protective tab that needs to be removed.
There are two methods for mounting the transmitter:
Method A: Using Double-Sided Adhesive Tape
- Clean the mounting surface thoroughly to ensure it is free of dust and moisture.
- Peel off one side of the protective film from the double-sided adhesive tape and attach it to the back of the transmitter.
- Peel off the other side of the protective film and firmly press the transmitter onto the desired location on the wall or door frame for at least 30 seconds.
Method B: Using Screws and Anchors
- Open the transmitter casing using the provided screwdriver.
- Mark the desired drilling points on the wall using the transmitter's back plate as a template.
- Drill two holes at the marked positions. Insert the anchors into the holes.
- Align the transmitter's back plate with the holes and secure it with the screws.
- Reattach the front casing of the transmitter.

Customizing Transmitters with Different Tones
You can assign a unique melody to each transmitter, allowing you to differentiate between multiple entry points (e.g., front door, back door).
- Select the desired melody on the receiver using the 'Music' button.
- Immediately after selecting the melody, press and hold the 'Volume' button on the receiver for approximately 5 seconds until you hear a 'ding' sound and the LED indicator flashes rapidly. This indicates pairing mode.
- Within 5 seconds, press the button on the specific transmitter you wish to pair with this melody. The receiver will sound the selected melody, confirming successful pairing.
- Repeat this process for each additional transmitter, selecting a different melody for each if desired.

Memory Function
The receiver is equipped with a memory function. It will remember your last selected melody and volume level even after a power outage, eliminating the need to reset your preferences.
Maintenance
Cleaning
Wipe the doorbell units with a soft, dry cloth. Avoid using abrasive cleaners or solvents, as these can damage the surface. The transmitter has an IP55 dustproof and waterproof rating, meaning it is protected against dust ingress and low-pressure water jets from any direction. However, it is not designed for submersion.
Battery Replacement (Transmitter)
The transmitter uses a CR2 lithium battery, which typically lasts up to 3 years. When the transmitter's performance degrades or the LED indicator no longer flashes upon pressing, it's time to replace the battery.
- Open the transmitter casing using the provided screwdriver.
- Carefully remove the old CR2 battery.
- Insert a new CR2 battery, ensuring correct polarity (+/-).
- Close the transmitter casing securely.
