Intelligent Overheat Protection
The light will accumulate a lot of heat when used at relatively high modes for extended periods.
When the light reaches a temperature of 60°C or above, the light will automatically step down a
few lumens to reduce the temperature. When the temperature drops below 60°C, it will then
allow the user to reselect the modes.
Low-voltage Warning
When the voltage level drops below the preset level, the bicycle light is programmed to
downshift to a lower brightness level until Low mode is reached. When this happens in Low
mode, the battery level indicator constantly blinks red to remind you to recharge or replace the
battery.
Note: This only works with Fenix ARB-L18 Series 18650 rechargeable Li-ion battery.
Usage and Maintenance
l
Disassembling the sealed head can cause damage to the light and will void the warranty.
l
Fenix recommends using only a high-quality protected battery.
l
If the light will not be used for an extended period, remove the battery for proper storage.
l
Unscrew the tail cap or remove the battery to prevent accidental activation during storage
or transportation.
l
Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring
with an approved spare
．
l
Periodic cleaning of the battery contacts improves the light's performance as dirty contacts
may cause the light to flicker, shine intermittently or even fail to illuminate for the following
reasons:
A: Poor battery level.
Solution: Recharge or replace the battery.
B: The contact or contact point of the battery or bicycle light is dirty.
Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.
If the above methods don't work, please contact your authorized distributor.
