  • 2C: Go to/from highest safe level
  • 3C: Toggle between Smooth Ramping and Stepped Ramping
  • 4C: Lockout mode
• In Lockout Mode (Simple UI):
  • 1H: Momentary moon
  • 2H: Momentary low
  • 4C: Unlock and turn on
  • 4H: Unlock and turn on at low level
  • 5C: Unlock and turn on at high level

FAQ

• Why won't the item work without being plugged in?
  Solution: Unscrew the body, remove the round insulating paper/sheet, screw the body back on, and try again.
• Why is the item flashing improperly?

Usage and Maintenance

• Disassembling the sealed head can damage the light and void the warranty.
• Sofirn recommends using high-quality batteries. Remove the battery if the flashlight will not be used for an extended period to prevent damage from electrolyte leakage or battery explosion.
• To prevent accidental activation during storage or transportation, unscrew the tail cap by half a turn or remove the battery.
• Clean the threads every 6 months with a cleaning cloth. Applying silicone grease to the threads is recommended.
• Long-term use may cause O-ring wear. Replace worn O-rings with approved spares to maintain a proper water seal.
• Periodically clean battery contacts to ensure optimal performance. Dirty contacts can cause flickering, intermittent illumination, or failure to light up due to:
  • Reason A: Battery needs replacement.
    Solution: Replace the battery and confirm correct installation.
  • Reason B: Threads, PCB board contacts, or other contacts are dirty.
    Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.
