Before first use, fully charge the alarm unit. Connect the provided USB-C charging cable to the alarm's charging port and plug the other end into a standard USB power adapter (not included).

Choose a discreet location that allows the alarm sound to be heard clearly and where it is less likely to be tampered with.
The remote control is typically pre-paired with the alarm unit from the factory. If for any reason the remote does not control the alarm, or if you wish to pair a new remote, please refer to the troubleshooting section or contact customer support for detailed pairing instructions.

Press the Arm Button (locked padlock icon) on the remote control. The alarm will emit a short beep, indicating it is armed. Any significant vibration or movement detected will now trigger the alarm.
Press the Disarm Button (unlocked padlock icon) on the remote control. The alarm will emit a short beep, indicating it is disarmed. You can now move your protected item without triggering the alarm.

Image: Two scenarios illustrating the SOS function: no alarm when tilt is less than 45 degrees, and automatic alarm activation when tilt exceeds 45 degrees.
The alarm is equipped with an automatic SOS function. If the alarm unit detects a tilt of more than 45 degrees (e.g., if a bicycle falls over or is pushed down), it will automatically trigger a loud alarm to alert you and others nearby. This feature is active when the alarm is armed.
Press the Bell Button (bell icon) on the remote control. The alarm unit will emit a short, distinct sound, helping you locate your vehicle in a crowded parking area or if it's out of sight.
