5. Maintenance
5.1. Battery Replacement
The door sensor is powered by an alkaline battery designed for ultra-low power consumption, allowing it to last for approximately 7200 activations. When the sensor's performance degrades or it stops transmitting signals, it is time to replace the battery.
- Carefully open the sensor casing.
- Remove the old alkaline battery.
- Insert a new, compatible alkaline battery, ensuring correct polarity.
- Close the sensor casing securely.

5.2. Cleaning
Wipe the sensor and receiver with a soft, dry cloth. Do not use liquid cleaners or abrasive materials, as these can damage the devices.
6. Troubleshooting
- No Chime Sound:
- Ensure the receiver is properly plugged into a working electrical outlet.
- Check the volume level on the receiver; it might be set to 0dB (silent).
- Verify the sensor battery. Replace if necessary.
- Confirm the sensor parts are within 0.4 inches when the door/window is closed.
- Re-pair the sensor and receiver if they have lost connection (refer to pairing instructions, if available, or contact support).
- Short Wireless Range:
- Obstructions like thick walls, metal structures, or other electronic devices can interfere with the wireless signal. Try relocating the receiver or sensor.
- Ensure the sensor battery is not low.
- False Alarms:
- Ensure the sensor parts are securely mounted and do not shift, causing intermittent contact.
- Verify the gap between the sensor parts is consistently less than 0.4 inches when closed.
