LED assembly; screw the bezel back on to test.
Usage and Maintenance
◎ Please don’t disassemble the sealed head as doing so can cause damage to the flashlight and will void the warranty.
◎Use only recommended high performance batteries with this high discharge light: A NiMH rechargeable cell is recommended as alkaline batteries will reduce the flashlight’s
runtime.
◎We recommend the use of high quality batteries. If the flashlight is not to be used for
an extended period, remove the batteries, or the flashlight could be damaged by electrolyte leakage or battery explosion.
◎Due to the momentary-on tactical switch, the flashlight may be accidentally activated when stored, transported or placed in a pocket. Unscrew the tail cap one-half turn or take out the battery to avoid unwanted operation.
◎ 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 flashlight’s performance as dirty
contacts may cause the LD09 to flicker, shine intermittently or even fail to illuminate for the following reasons: Reason A: The battery needs 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”.
