3.3 Pairing Transmitter and Receiver
If you need to re-pair a transmitter (sensor) with a receiver, or pair additional sensors, follow these steps:
- Step 1: Select Ringtone. On the receiver, short press the Forward (▲) or Backward (▼) button to select your desired ringtone. The receiver will play the selected music.
- Step 2: Enter Pairing Mode. Long press the Volume button (🔊) for 5-8 seconds until the receiver makes a "ding" sound and the LED display flashes. This indicates it's in learning mode.
- Step 3: Select Transmitter Number. Short press the Forward (▲) or Backward (▼) button to select a corresponding number (1-9) for the transmitter you are pairing.
- Step 4: Trigger Transmitter. Separate the two parts of the door magnet (sensor) by more than 1cm. The transmitter's LED will flash red, and the receiver will make two "ding" sounds.
The transmitter and receiver are now successfully paired. The learning mode lasts only 8 seconds, so complete steps 3 and 4 promptly.

4. Operating Instructions
4.1 Door/Window Monitoring
When the transmitter (sensor) is close to the magnetic strip (door/window closed), no alarm will sound. When the transmitter is separated from the magnetic strip by more than 1cm (door/window opens), the receiver will sound an alarm.

4.2 Adjusting Volume and Ringtones
The receiver offers 55 classic ringtones and 5 adjustable volume levels, ranging from 0 to 110dB. You can also mute the chime. The system includes a memory function, retaining your previously set tune even after reinsertion or power loss.
- Volume Adjustment: Short press the Volume button (🔊) to cycle through the 5 volume levels.
- Ringtone Selection: Short press the Forward (▲) or Backward (▼) button to select from the 55 available ringtones.

4.3 Wide Coverage and Expansion
The wireless doorbell has a range of up to 1000 feet (300 meters), suitable for covering various areas in your home or business. With up to 64,000 learning codes, the system can be expanded with additional wireless doorbells. You can pair different chimes with different sensors to identify which door has been triggered.

5. Maintenance
5.1 Battery Replacement
The battery-powered sensors use CR2450 3V button batteries. These batteries offer ultra-long standby time, lasting approximately 3-5 years without frequent replacement. When the sensor's LED indicator no longer flashes or the signal becomes unreliable, it is time to replace the battery.
- To replace the battery, carefully open the sensor casing using the mini screwdriver provided.
- Remove the old CR2450 battery and insert a new one, ensuring correct polarity.
- Close the casing securely.

5.2 Cleaning
Wipe the surfaces of the receivers and sensors with a soft, dry cloth. Do not use abrasive cleaners or immerse the devices in water.
6. Troubleshooting
6.1 No Sound or Intermittent Alerts
- Check Power: Ensure the receiver is securely plugged into a working electrical outlet.
- Check Sensor Alignment: Verify that the two parts of the sensor are within 1cm when the door/window is closed. Misalignment can prevent proper triggering.
- Battery Check: Replace the sensor battery if it is low or depleted.
- Range Issues: While the system has a wide range, extreme distances or significant obstructions (thick walls, metal structures) can interfere with the signal. Try repositioning the receiver or sensor.
- Re-pair Devices: If the issue persists, try re-pairing the specific sensor with the receiver following the steps in Section 3.3.
6.2 Difficulty Changing Ringtones or Programming
Some users may find the programming process challenging initially. Ensure you follow the pairing steps precisely, especially the timing for long-pressing buttons and triggering the sensor within the 8-second learning window.
6.3 How to Clear and Reset Paired Devices
To clear all paired transmitters and reset the receiver, follow these steps:
- Press and hold the Backward (▼) button on the receiver for approximately 5 seconds.
- You will hear a 'ding' sound from the receiver accompanied by the LED light flashing. This indicates that the set ringtone and all paired transmitters/receivers have been cleared.
Video: Demonstrates how to clear and reset the receiver, which unpairs all connected sensors and resets the ringtone.
