6. Operating Instructions

6.1 Arming the Alarm

Press the Arm button (locked padlock icon) on the remote control. The alarm unit will emit a short beep to confirm it is armed. Any significant movement detected after arming will trigger the alarm.

6.2 Disarming the Alarm

Press the Disarm button (unlocked padlock icon) on the remote control. The alarm unit will emit a short beep to confirm it is disarmed. The alarm will not trigger from movement while disarmed.

6.3 Changing Alarm Tone

Press the Tone Select button (lightning bolt icon) on the remote control to cycle through the available alarm tones. The alarm will play a sample of each tone as you press the button.

6.4 Vehicle Finder Function

Press the Vehicle Finder button (bell icon) on the remote control. The alarm unit will emit a short, distinct sound, allowing you to locate your vehicle in a crowded area without triggering the full alarm.

7. Adjusting Sensitivity

The alarm features 7 levels of sensitivity, from least sensitive (level 1) to most sensitive (level 7). This allows you to customize the alarm's responsiveness to movement. To adjust the sensitivity:

1. Ensure the alarm is disarmed.
2. Press and hold the Tone Select button (lightning bolt icon) on the remote control for approximately 3 seconds until you hear a "Di" sound.
3. The alarm will then emit a series of "Di" sounds, indicating the current sensitivity level (e.g., one "Di" for level 1, seven "Di"s for level 7).
4. Press the Tone Select button again to cycle through the sensitivity levels. Each press will increase the sensitivity by one level. After level 7, it will loop back to level 1.
5. Once you have selected your desired sensitivity level, wait for 5 seconds without pressing any buttons. The alarm will automatically save the setting and exit the sensitivity adjustment mode.

2. Use the provided screwdriver to open the battery compartment cover.
3. Remove the old AAA batteries.
4. Insert 3 new AAA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
