Warning: When the voltage level drops below a preset level, the flashlight is programmed to
downshift to a lower brightness level until Low output is reached. To ensure normal use, the
flashlight will not turn off automatically and will work till the battery runs out completely.
Battery Replacement ②
Unscrew the head to insert the battery with the anode side (+) towards the light head, then
screw the light head back on.
Intelligent Memory Circuit
The light memorizes the last selected brightness level. When turned on again the previously used
brightness level will be recalled.
Time-limited Downshift
The light will accumulate a lot of heat when used on High output level for extended periods.
When the light has been used on High for 3 minutes, the light will automatically step down by a
few lumens until 60 lumens is reached to reduce the temperature. High mode can be reselected.
Usage and Maintenance
Disassembling the sealed head can cause damage to the light and will void the warranty.
Fenix recommends using excellent quality batteries.
Fenix strongly recommends using
batteries to get the most out of this light. Alkaline batteries will reduce the
runtime relatively.
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.
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:
A: The battery needs replacing.
Solution: Replace battery (Ensure battery is inserted according to the manufacturer's
specifications).
B: The threads, PCB board contact or other contacts are dirty.
Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.
