Note: This only works with Fenix ARB-L16-700P 16340 rechargeable Li-ion battery.
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 flashlight is programmed to downshift
to a lower brightness level until Low output is reached. When this happens in Eco output mode,
the battery level indicator blinks red to remind you to timely recharge or replace the battery.
Note: This only works with Fenix ARB-L16-700P 16340 rechargeable Li-ion battery.
Usage and Maintenance
Disassembling the sealed head can cause damage to the light and will void the warranty.
Fenix recommends using only a high-quality protected battery.
If the light will not be used for an extended period, remove the battery for proper storage.
Unscrew the tail cap or remove the battery to prevent accidental activation during storage
or transportation.
Long-term use can result in O-ring wear. To maintain a proper water seal, replace the ring
with an approved spare．
