2. 90° Rotatable Head

The unique 90° rotatable head allows for flexible light direction, converting the flashlight from a standard handheld light to an L-shaped work light or headlamp (with optional accessories).

Maintenance

• Cleaning: Clean the flashlight body with a soft, damp cloth. Do not use abrasive cleaners or solvents.
• Battery Care: Recharge the battery regularly, even if not in use, to maintain optimal performance and extend its lifespan. Store the flashlight with a partially charged battery if not used for extended periods.
• O-rings: Periodically check and lubricate the O-rings with silicone grease to maintain the IP65 waterproof rating. Replace damaged O-rings as needed.
• Water Resistance: The flashlight is IP65 waterproof, meaning it is protected against dust and low-pressure water jets. It is not designed for submersion. Ensure the USB-C port cover is securely closed to maintain water resistance.

Troubleshooting

  • Ensure the insulating sheet has been removed from the battery compartment (refer to Setup section).
  • Check if the battery is charged. If not, connect the flashlight to a power source using the USB-C cable.

  • If the lockout function is active (flashlight blinks when trying to turn on), double-click and hold the side switch for 2 seconds to deactivate it.
• Light output is dim or flickering:
  • The battery may be low. Recharge the battery.
  • Ensure the battery contacts are clean and free from debris.
