Usage and Maintenance of the TK22 Flashlight

•
Disassembling the sealed head can cause damage to the light and will void the warranty.
•
Fenix recommends using a high-quality battery.
•
If the light will not be used for an extended period, remove the battery, or the light could be damaged by
electrolyte leakage or battery explosion.
•
Unscrew the tail cap half a turn or take out the battery to prevent accidental activation during storage or
transportation. Recharge a stored battery every four months to maintain optimal battery performance.
•
When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower
brightness level until Low output is reached. When this happens in Low output mode, the flashlight blinks three
times every five minutes to remind you to replace the battery. To ensure normal use, the flashlight will not turn
off automatically and will work till the battery runs out completely.
•
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 lamp's performance as dirty contacts may cause the lamp
to flicker, shine intermittently, or even fail to illuminate for the following reasons:
o A: The battery needs replacing.
▪
o B: The threads, PCB board contact or other contacts are dirty.
▪
If the above methods don't work, please contact your authorized distributor.
