It features emergency illumination upon activation, a quick torch function, adjustable vibration alerts, and an anti-theft security alarm. Additionally, the Do Not Disturb setting helps prevent unwanted triggers during heavy weather, while a battery level monitor keeps track of power, issuing warnings for low battery status.
