OPERATIONS
ON/OFF
Press and hold the light button for 0.5 seconds to turn ON/OFF the light.
Output Selection
With the light on, click the light button to cycle through Low→Mid→High→Turbo→Flash.
Note:
As with any performance light, the bike light builds up heat when it runs for an extended period. Intelligent circuitry in the bike light downshifts the light to lower brightness level to guard against overheating.
The bike light retains the last-used brightness level.
When the battery power level is critical, higher brightness levels can not be activated, and the bike light is programmed to cycle through lower brightness levels.
Battery Level Indicator
With the light off, single-click the light button, the side light will indicate the battery power level conditions, and then go out after 5 seconds.
Side light constant-on (sufficient power level): 60%-100%
Side light slow flashing (low power level): 20%-60%
Side light quick flashing (critical power level): 1%-20%
Low Power Warning and Intelligent Output Downshift
Low Power Warning: With the light on, when the battery level is lower than 20%, the light button will blink red constantly, to remind you to downshift to a lower brightness level to extend runtime or recharge the bike light.
Intelligent Output Downshift:
If non-stop use is needed, the light will downshift to a lower output level to extend runtime. When it downshifts to the flashing mode, the bike light will go out soon. Please stop riding and replace the battery or the bike light.
Charging
Operation Points: Remove the anti-dust plug at the bottom of the bike light to reveal the charging port, and plug the Micro USB end of the USB cable into the light’s charging port, then connect the other end of the USB cable to a USB power adaptor.
Charging Indicator: The indicator light in the bike light blinks red to indicate the charging process has begun. The indicator light turns solid green when the battery is fully charged.
Note:
Turning on the bike light under charging state is not recommended by Fenix. But it will be okay if under emergency situations, the bike light can light up at Low and Mid output.
Once charging is completed, disconnect the USB cable from the light and be sure to secure the anti-dust plug cover.
Fenix recommends using a power adaptor with output over 5V 1.5A. It takes about 4 hours to fully charge the bike light.
The bike light can be connected to the USB cables for digital products such as mobile phones with standard Micro-USB charging port.
