head back on to test.
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 flashlight should use battery with high current discharge ability; we suggest using
high performance Ni-MH rechargeable battery, using alkaline battery will lower the runtime of
high intensity flashlight.
Please use battery of high quality, and take out 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 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 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 an alcohol soaked cotton swab.
If the above methods don't work, please contact the distributors and refer to the warranty policy.
