2. Press the lock button to lock the disc brake and you will hear the "beep" sound. When the bike is moved (the lock will vibrate), it will sound a "beep beep beep" warning alarm three times in case of an accident.
3. When it vibrates again, it will emit a continuous shrill alarm for 10 seconds. The alarm will stop immediately when you use the correct key to open the lock.
Replacing the battery:
When you hear sounds as low as "beep beep beep" or a warning alarm sounds for less than 10 seconds, it indicates that the batteries need to be replaced. To replace them, simply use the provided hex key (Allen key) to unscrew the 4 screws on the lock then lift the cover to remove the batteries.
