1. Door lock voice prompt "battery out":
This alarm sound is a low voltage alarm for the door lock battery, reminding the user to replace the battery in time.
2. Unable to open the lock electronically when the battery is out of power:
You can use the Micro-USB interface to connect to an external power bank to unlock the emergency power supply or use a mechanical key to unlock.
3. If you use the wrong way to unlock the door for many times, the door lock will emit a "Woooo" alarm sound and cannot be opened:
This is the door lock anti-test opening alarm. At this time, the door lock is in the locked state, which is used to improve the safety of the door lock. After the door lock has issued an alarm, you need to wait 5 minutes for the alarm to be released when you are outdoors and unlock it again. When indoors, you can press down on the handle to unlock, or remove the battery and reinstall it to cancel the alarm sound.
4. Emergency mechanical key is lost:
It is recommended to contact our after-sales service personnel in time to replace the new mechanical lock cylinder and key.
