User Manual for Disc Brake Lock 

1. When the lock cylinder is pressed halfway to lock, it is in non-alarm mode, and vibration will not trigger an alarm sound. When the lock cylinder is pressed all the way down, an alarm sound will be emitted, and it will immediately enter alarm mode.
2. When the lock body is shaken, it will emit 3 warning beeps. If the lock body is touched again, it will immediately sound a continuous alarm. Each alarm lasts for about 10 seconds.
3. If the owner unlocks within 5 seconds, the alarm will not be triggered, and unlocking will release the alarm.
4. When you hear a continuous "click-click-click" sound, the battery needs to be replaced.
