2. Receiver Placement
- Plug the receiver into any standard electrical outlet within range of the sensor.
- Ensure the receiver is not obstructed by large metal objects or other electronic devices that could interfere with the wireless signal.

3. Sensor Installation
- Identify the desired door or window for monitoring.
- Mount the larger sensor unit on the fixed frame of the door/window using adhesive tape or screws (not included).
- Mount the smaller magnetic contact on the moving part of the door/window, aligning it with the main sensor unit. The gap between the two parts should be no more than 10mm when the door/window is closed.
- Ensure both parts are securely attached and remain aligned when the door/window is closed.

4. Pairing (If necessary)
The sensor and receiver are typically pre-paired. If pairing is lost or you are adding new sensors:
- Plug in the receiver.
- Press and hold the volume button on the receiver for approximately 3-5 seconds until the LED indicator flashes rapidly. This indicates pairing mode.
- Within 10 seconds, separate the two parts of the magnetic sensor (open the door/window). The receiver should chime, indicating successful pairing.
- Test the sensor by opening and closing the door/window to confirm the chime sounds.
Operating Instructions
Volume Adjustment
Press the volume button on the side of the receiver to cycle through available volume levels. There are multiple levels, including a silent mode.
Chime Tone Selection
Use the 'Forward' and 'Backward' buttons on the side of the receiver to browse through the 52 available chime tones. The selected tone will play immediately. The receiver will remember your last selected tone.
Maintenance
