The alarm can be mounted using the included double-sided stickers or cable ties:

  1. Using Double-sided Stickers: Clean the surface where you intend to mount the alarm. Peel off one side of a double-sided sticker and firmly press it onto the back of the alarm unit. Then, peel off the other side and attach the alarm to the desired clean, flat surface on your bike, scooter, or other item. Ensure a strong bond.
  2. Using Cable Ties: Thread the provided cable ties through the designated slots on the alarm unit. Securely fasten the alarm to a suitable frame part of your bicycle or scooter, such as the seat post or frame tube. Trim any excess cable tie length.

Choose a discreet location that allows the alarm sound to be heard clearly and where it is less likely to be tampered with.

3. Remote Control Pairing (Pre-paired)

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.

The alarm has 7 adjustable sensitivity levels. To change the sensitivity:

  1. Press the Disarm Button to ensure the alarm is disarmed.
  2. Press and hold the Ringtone Button (lightning bolt icon) until you hear a series of beeps. The number of beeps indicates the current sensitivity level (e.g., 1 beep for lowest, 7 beeps for highest).
  3. Release the button, then press it again repeatedly to cycle through the sensitivity levels. Each press will increase the sensitivity by one level, accompanied by a corresponding number of beeps.
  4. Once you reach your desired sensitivity level, stop pressing the button. The alarm will automatically save the setting after a few seconds of inactivity.

4. Automatic SOS Function

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.

5. Vehicle Locating (Bell Function)

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.
