Charging the Flashlight

The SV72 flashlight is equipped with a Type-C USB charging interface. To charge the device:

1. Locate the rubber cover on the side of the flashlight, protecting the charging port.
2. Gently lift the rubber cover to expose the Type-C USB port.
3. Connect the provided USB charging cable to the flashlight's Type-C port and plug the other end into a compatible USB power source (e.g., USB plug, charging treasure, phone charger, car charger, notebook).
4. The battery indicator lights (purple LEDs) on the flashlight will illuminate to show the charging progress.
5. Once fully charged, disconnect the cable and securely close the rubber cover to protect the port from dust and moisture.

Battery Installation

The SV72 flashlight uses a 1x26650 battery. The battery is typically pre-installed. If replacement is necessary, unscrew the tail cap, insert the 26650 battery with the positive (+) end facing the head of the flashlight, and then securely re-screw the tail cap.

Operating Instructions

Power On/Off and Light Source Selection

The flashlight features a single power switch for operation:

• Short Press: Turn the flashlight ON/OFF.
• Long Press: Switch between the 365nm UV light source and the XHP50 LED white light source.

Using the 365nm UV Light

The 365nm UV light is designed for various detection and identification purposes:

• Pet Urine Detection: Illuminate dark areas to reveal hidden pet urine stains on carpets, furniture, or floors.
• Scorpion Finder: Scorpions fluoresce under UV light, making them easier to spot in dark environments.
• Currency and Document Authentication: Verify security features on banknotes, licenses, cards, and passports that are visible only under UV light.
• Fluorescent Agent Detection: Identify fluorescent agents in cosmetics, textiles, or other materials.
• Oil Stain and Leakage Detection: Locate oil leaks or stains that fluoresce under UV light.
• Ore and Antique Identification: Observe the fluorescence of certain minerals and antique items for authentication.
• UV Glue Curing: Can be used for curing UV-sensitive adhesives.

Using the XHP50 LED White Light

The XHP50 LED white light provides powerful general illumination for various tasks, including:

• General lighting in dark areas.
• Outdoor activities such as camping, hiking, or night walks.
• Emergency lighting.

Power Output (Charging other devices)

The SV72 flashlight can also function as a power bank, allowing you to charge other devices via its USB-A output port while you continue to use the flashlight.

Maintenance

• Cleaning: Wipe the flashlight body with a soft, damp cloth. Do not use abrasive cleaners or solvents. Keep the lenses clean for optimal performance.
• Storage: Store the flashlight in a cool, dry place away from direct sunlight and extreme temperatures.
• Battery Care: To prolong battery life and prevent damage, avoid completely draining the battery. Always leave some charge margin. Recharge the battery regularly, even if not in frequent use.
• Water Resistance: The flashlight is waterproof, but avoid prolonged submersion in water. Ensure all covers (e.g., charging port cover) are securely closed before exposure to water.

Troubleshooting

• Flashlight not turning on: Check if the battery is charged. Ensure the battery is correctly inserted with the positive (+) end facing the head.
• Light output is dim: The battery may be low. Recharge the flashlight.
• Cannot switch between UV and white light: Ensure you are performing a long press on the power switch. A short press only turns the device on/off.
• Battery damage due to over-discharge: As noted in the product description, completely draining the battery can cause irreversible damage. Always leave some charge margin.
