Usage and Maintenance
◎ Please don't disassemble the sealed head as doing so can cause damage to the flashlight and
will void the warranty.
◎The circuit is programmed with a low-voltage protection function. If low voltage is detected, it
will enter into the lower brightness level. If low voltage is detected in the Low brightness level,
it will blink three times a second every 5 minutes. To allow normal use, LD41 will not turn off
automatically and will continue to work until the batteries are depleted.
◎ To get the most from this LD41, Fenix recommends using high-performance Ni-MH
.
rechargeable batteries. Alkaline batteries will reduce runtimes significantly
◎ If the flashlight is not to be used for an extended period, remove the batteries as the flashlight
could be damaged by electrolyte leakage or battery explosion.
◎ To avoid accidental activation, remove the batteries before packing and transporting the LD41.
◎ 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 LD41to 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".
