1. Press the lock button to lock the disc brake, and you will hear the sound "beep". When the lock is vibrated the lock will give off an alarm "beep beep beep" 3 times in case this is just a bump. When vibrated again will give off a continuous shrill alarm for 10-12 seconds. And it keeps alarm with serial vibration.

2.The Reminder cable/cord has a loop at each end to connect your disc lock to your hand grip. It will remind you to remove the lock when you are going out for a ride.
