4.2. Sensor Installation
- Identify the desired door or window for sensor placement. Clean the surface thoroughly to ensure proper adhesion.
- Peel off the backing from the double-sided adhesive tape provided.
- Attach the larger sensor unit to the door or window frame.
- Attach the smaller magnetic strip to the moving part of the door or window, aligning it with the larger sensor unit. The distance between the two parts should be no more than 0.4 inches (1.5 cm) when the door/window is closed.

4.3. Pairing Sensors with Receiver
The doorbell and receiver are typically pre-paired from the factory. If re-pairing is needed or you wish to add more sensors:
- Select your desired ringtone on the receiver by pressing the ringtone selection button.
- Press and hold the middle volume key on the receiver for 5-8 seconds until you hear a 'ding' sound and the LED indicator flashes rapidly. This indicates pairing mode.
- Separate the two parts of the door sensor. The sensor's indicator light will flash, and the receiver will emit two 'dingding' sounds, confirming successful pairing.

- Carefully open the sensor casing using a small screwdriver or by gently prying it open.
- Remove the old CR2032 battery from the circuit board.
- Insert a new CR2032 battery, ensuring correct polarity.
- Close the sensor casing securely.
