Usage and Maintenance

• Disassembling the sealed head can cause damage to the headlamp and will void the warranty.
• Excellent quality Fenix Li-ion batteries are strongly recommended for this high-power lamp.
• Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring with an approved spare.

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.
