4. Setup and Installation
4.1. Transmitter Installation
Choose a suitable location for your doorbell transmitters, such as near your front door or back door. Ensure the surface is clean and dry.
- Check Battery: The 12V A23 battery is typically pre-installed. If not, open the transmitter casing and insert the battery, observing polarity.
- Mounting Options:
- Adhesive Mounting: 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 clean, flat surface for at least 30 seconds.
- Screw Mounting: Open the transmitter casing. Mark the positions for the screw holes on your chosen surface. Drill pilot holes if necessary, insert wall anchors (for masonry/drywall), and then secure the transmitter's back plate with the provided screws. Snap the front casing back onto the secured back plate.

The receiver offers 5 adjustable volume levels, including a mute mode.

Your doorbell system typically comes pre-paired. If you need to re-pair a transmitter or add new ones (up to 32), follow these steps:

- 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 10 seconds, quickly press the button on the desired transmitter. The receiver will chime, confirming successful pairing.
- Repeat for any additional transmitters.
- To exit pairing mode, press the Volume Button again or wait 10 seconds for it to automatically exit.

- Insert a new 12V A23 battery, ensuring correct polarity (+ and -).
- Close the transmitter casing securely.
7.2. Cleaning
