Charging
- Open the anti-dust cap and plug the USB Type-C end of the charging cable into the charging port of the lantern.
- While charging, the switch light ring will progressively display green in a counterclockwise direction to indicate the charging status.
- The switch light ring will turn green completely when the lantern is fully charged.
Note:
- All outputs can be turned on while charging.
- The Delay off function can be used while charging. In this case, the switch light ring will prioritize indicating the charging status.
- With the lantern turned off, the normal charging time is approximately 2.5 hours from depleted to fully charged*.
- Once charging is completed, be sure to unplug the charging cable and close the anti-dust cover to prevent the ingress of dust and debris.
- It is recommended to recharge the lantern when the battery level is between 50% and 25% to prolong the battery lifespan. Immediate charging is required when the remaining battery level falls below 25%.
*This function only works with a Fenix ARB-LP1900 battery. Do not connect the charging cable to the lantern while using the AAA batteries.
Battery Level Indication
Each time the lantern is turned on, the switch light ring will indicate the battery level and will last for 3 seconds. With the lantern turned off, single click the switch to check the current battery level and the switch light ring will last for 3 seconds.
- Green light on: saturated 100% - 85%
- Green light flashes: sufficient 85% - 50%
- Red light on: poor 50% - 25%
- Red light flashes: critical 25% - 1%
*This function only works with a Fenix ARB-LP1900 battery.
Intelligent Overheat Protection
The lantern will accumulate a lot of heat when used for extended periods. When the lantern reaches a temperature of 50°C/122°F or above, it will automatically step down a few lumens to reduce the temperature. When the temperature drops below 50°C/122°F, the lantern will gradually recall the preset output level.
Low-voltage Warning
When the voltage level drops below the preset level, the switch light ring blinks red 6 times every 1 second to remind users to recharge or replace the battery in a timely manner. To ensure normal use, the lantern will not turn off automatically and will work till the battery runs out.
