Usage and Maintenance
- Please don’t disassemble the sealed head, doing so can cause damage to the flashlight and will void the warranty.
- High-power lights should use batteries with high current discharge capability; We suggest using high-performance Ni-MH rechargeable batteries to increase the runtime of this high-intensity light.
- Please use high-quality batteries, and remove the battery if the flashlight will not be used for a long time, or it may cause damage from electrolyte leakage or battery explosion.
- The o-ring may wear out after long-term use. If this occurs, replace the o-ring with a new one to keep the light properly sealed against water.
- Please clean the contacts of your light periodically, especially if the light flickers or does not turn on. There may be several reasons for a flickering or non-working light: Reason A: The battery needs replacing. Solution: Replace the battery (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 an alcohol-soaked cotton swab.
If the above methods do not work, please contact your distributor and refer to the warranty policy.
Notice: The routine cleaning video can be watched and downloaded through the Fenix official website. Please log onto the service channel and navigate to ‘maintenance for light’.
