Battery Replacement
Unscrew the tail cap to insert the battery with the anode side (+) towards the light head, then screw the tail cap back on.
Intelligent Overheat Protection
The light will accumulate a lot of heat when used on higher output levels 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 for the reselection of higher 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 Eco output is reached. When this happens in Eco output, the light blinks 3 times every 5 minutes to remind you to recharge or replace the battery.
Note: This only works with Fenix ARB-L21 Series 21700 rechargeable Li-ion battery.
