Introdución
The Alonefire SV103/SV101 UV Flashlight is a versatile ultraviolet black light designed for a wide range of detection tasks. This manual provides essential information for the safe and effective use of your UV flashlight, covering setup, operation, maintenance, and troubleshooting.
The flashlight is available in two main configurations: the SV103 with 3x365nm UV LEDs and the SV101 with 1x365nm UV LED. Both models are rechargeable via a Type-C USB interface and are constructed from durable aluminum alloy.

Configuración
Instalación de baterías
The flashlight uses one 18650 battery. To install or replace the battery, unscrew the tail cap, insert the 18650 battery with the positive (+) end facing towards the head of the flashlight, and then securely screw the tail cap back on.

The flashlight features a convenient Type-C USB charging interface. To charge, locate the rubber cover on the side of the flashlight, open it, and connect a Type-C USB cable to a compatible power source (e.g., mobile phone charger, computer, power bank, car charger). The charging indicator light will show red when charging and green when fully charged.

Instrucións de funcionamento

Consellos para o usuario
- Detección óptima: For best results when detecting stains or fluorescent materials, use the UV flashlight in a dark environment. The effect of UV light is significantly enhanced without ambient visible light.
- 365nm vs. 395nm: While this flashlight primarily uses 365nm UV light, it's important to understand the difference. 365nm UV light is less visible to the naked eye but is more effective for detecting high-demand fluorescent agents and security codes, offering a clearer fluorescence without much visible purple glow. 395nm UV light (not the primary wavelength of this product, but often compared) is brighter and shows a more visible purple light, which can sometimes obscure the fluorescence of certain materials.
- Portabilidade: The detachable clip allows for convenient pocket carry, making it easy to transport and access when needed.
