4. Operating Instructions
4.1 Arming and Disarming
- Arm: Press the lock button on the remote control. The alarm will emit a confirmation sound, indicating it is armed. Any significant vibration or movement will trigger the alarm.
- Disarm: Press the unlock button on the remote control. The alarm will emit a confirmation sound, indicating it is disarmed.
4.2 Adjusting Sensitivity
The AL-16 alarm features 5 levels of adjustable sensitivity, from a gentle touch to a strong impact. This allows you to customize the alarm's responsiveness to suit your environment and needs. Refer to the remote control's specific buttons for sensitivity adjustment (usually indicated by a bell or sensitivity icon).
4.3 SOS Function
The alarm includes an SOS function designed to detect if the protected vehicle falls over. If the bicycle or scooter tilts beyond approximately 45 degrees, the alarm will automatically activate the SOS alert, emitting a distinct sound pattern to signal an emergency.
