ກ່ອນການໃຊ້ຄັ້ງທໍາອິດ, ໃຫ້ສາກແບັດເຕີຣີໃຫ້ເຕັມ.
- Locate the USB-C charging port on the flashlight body. It is typically covered by a rubber flap for water resistance.
- Open the rubber flap and insert the small end of the USB-C charging cable into the flashlight's port.
- Connect the larger USB-A end of the cable to a USB power source (e.g., computer USB port, wall adapter, power bank).
- The charging indicator light will turn ສີແດງ ໃນຂະນະທີ່ສາກໄຟ.
- ເມື່ອສາກໄຟເຕັມແລ້ວ (ປະມານ 4-5 ຊົ່ວໂມງ), ໄຟສັນຍານຈະສະຫວ່າງຂຶ້ນ ສີຂຽວ.
- Disconnect the charging cable and close the rubber flap to maintain water resistance.

5.2. Applications of 395nm UV Light
The 395nm UV wavelength is highly effective for detecting fluorescent substances. Here are some common uses:
- ການກວດປັດສະວະສັດລ້ຽງ: Easily spot dried pet urine stains on carpets, rugs, and furniture that are invisible to the naked eye.
- Currency and Document Authentication: Verify the authenticity of banknotes, passports, and other official documents that contain UV security features.
- Scorpion Detection: Scorpions glow brightly under 395nm UV light, making them easy to spot in dark environments.
- Mineral and Gemstone Inspection: Identify certain fluorescent minerals and gemstones.
- Resin Curing: Accelerate the curing process of UV-sensitive resins and glues.
- Bed Bug Detection: Locate bed bugs and their eggs, which may fluoresce under UV light.
- Hygiene Inspection: Reveal hidden stains and unsanitary areas in hotel rooms, bathrooms, and kitchens.

5.4. 395nm vs 365nm UV Light
While both 395nm and 365nm UV lights are used for fluorescence, they have different characteristics:
- 395nm UV (Alonefire SV103): This wavelength is more visible to the human eye, producing a noticeable purple glow. It is excellent for general detection of fluorescent materials, such as pet stains, currency, and scorpions, where a strong visual indication is desired.
- 365nm UV: This wavelength is closer to the true "black light" spectrum, emitting less visible light and more pure UV. It is often preferred for professional applications requiring minimal visible light interference, such as forensic analysis, specialized mineral identification, and some industrial curing processes.

Image: A comparison chart showing the effect of 365nm versus 395nm UV light on different minerals. Under normal light, the minerals appear dull. Under 395nm UV, some minerals show a purple glow. Under 365nm UV, the same minerals exhibit a more vibrant and distinct fluorescence, indicating the difference in their applications.
