The alarm device is housed in a waterproof stainless steel case, with inner silicone rubber gaskets located on the edges to effectively prevent rain or splashes from entering. The waterproof feature ensures that the device continues to function during rainy days without rusting.

Steps for Usage:

1. To lock the disc brake, press the lock button and you will hear a "beep" sound. In the event of vibration, the lock will sound an alarm with three beeps to signal an accident. If vibrated again, the Silver Knight will sound a continuous shrill alarm for 10-12 seconds and will continue to alarm with serial vibrations.
2. The Silver Knight requires 3-5 seconds to open the lock. If the key does not match, the lock will sound an alarm. Use the correct key to open the lock, and the alarm will stop immediately.

Battery Replacement: When the lock no longer produces sharp alarms but instead produces a constant sound of "Ge Ge Ge…", it means that the battery is going to be exhausted, and you need to replace it. To do this, use the Mini Wrench provided to unscrew the four screws at the bottom, remove the shell, and replace the battery. Be sure to pay attention to the anode "+" and cathode "-".
