Operating Instructions
Triggering an Emergency Alert
To activate an emergency alert, simply press the large 'SOS' button on either the wristband or pendant device. Upon activation:
- The receiver unit will emit an audible alarm and/or visual signal (depending on app settings).
- Your smartphone, and any other linked family members' smartphones, will receive an immediate notification via the Tuya Smart app.
- The system operates reliably as long as your smartphone maintains a Wi-Fi connection, ensuring alerts are transmitted even over long distances.

The third panel shows a person receiving an immediate notification on their smartphone, demonstrating the system's rapid response.
System Range and Connectivity
The system is designed for broad coverage within a typical home or care environment. The emergency buttons communicate wirelessly with the receiver, which then uses your home's 2.4GHz Wi-Fi network to send notifications to your smartphone. The effective range between the button and receiver can vary based on environmental factors such as walls and interference.

Maintenance
Battery Replacement
The emergency call buttons (wristband and pendant) are powered by CR2032 coin cell batteries. The receiver unit uses AAA batteries. When the battery in an emergency call button is low, an LED indicator will illuminate on the button itself. Additionally, the Tuya Smart app will send an immediate warning to your smartphone, prompting timely battery replacement.
To replace the CR2032 battery in the emergency call button:
- Carefully open the battery compartment on the back of the button.
- Remove the old CR2032 battery.
- Insert a new 3V CR2032 battery, ensuring the positive (+) side faces up.
- Close the battery compartment securely.

The text '90 Minuten' (90 minutes) is prominently displayed, which may refer to the battery's operational duration or a recommended replacement interval.
Troubleshooting
- No Notifications Received:
- Ensure your smartphone has a stable internet connection (Wi-Fi or mobile data).
- Verify that the Tuya Smart app has notification permissions enabled in your phone's settings.
- Check if the receiver unit is powered on and connected to your 2.4GHz Wi-Fi network.
- Confirm that the emergency call button has sufficient battery power. Replace if necessary.
- Limited Signal Range:
- The effective range between the emergency button and the receiver can be affected by thick walls, metal objects, or other wireless interference.
- Try repositioning the receiver unit to a more central location within the desired coverage area.
- Consider adding additional receivers or signal repeaters if a larger coverage area is required.
- Difficulty with App Setup:
- Ensure your Wi-Fi network is 2.4GHz. The device may not connect to 5GHz networks.
- Restart your router, smartphone, and the receiver unit, then attempt the pairing process again.
- Refer to the Tuya Smart app's help section for specific pairing instructions or common issues.
- Receiver Not Responding:
- Check if the receiver unit is properly plugged in and powered on.
