Usage and Maintenance 

• Disassembling the sealed head can cause damage to the light and will void the warranty.
• Fenix recommends using excellent quality battery. If the flashlight will not be used for an extended period, remove the battery, or the flashlight could be damaged by electrolyte leakage or battery explosion.
• Unscrew the tail cap one-half turn or take out the battery to prevent accidental activation during storage or transport.
• Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare.
• Periodic cleaning of the battery contacts improves the light’s performance as dirty contacts may cause the flashlight flicker, shine intermittently or even fail to illuminate for the following reasons: 
  Reason A: The batteries need replacing. 
  Solution: Replace batteries (Please confirm the correct installation of anode and cathode). 
  Reason B: The threads, PCB board contact or other contacts are dirty. 
  Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

If the above methods don't work, please refer to the warranty policy before contacting your authorized distributor. 

Notice: The routine cleaning video can be watched and downloaded through Fenix Official Website, please log onto the service channel->“maintenance for light”.
