Unscrew the tail cap to insert the batteries with the anode side (+) toward the light head, screw
the tail cap 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.
◎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 can be damaged by electrolyte leakage or
battery explosion.
◎ Due to the momentary-on tactical switch, the flashlight can be activated when stored,
transported or placed in a pocket. Unscrew the tail cap one-half turn to avoid unwanted
operation.
◎The o-ring may be worn out after using for a long time. If it happens, please replace the o-ring
with a new one to keep the flashlight properly sealed against water.
◎ Please clean the contacts of your light from time to time, especially if the light flickers or
doesn't light up. There may be several reasons for a flickering or not 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 don't work, please contact the distributors and refer to the warranty policy.
Notice: The routine cleaning video can be watched and downloaded through Fenix official
website, please log onto the service channel->"maintenance for light".
