Output Selection and Light Color Adjustment

• In Modes A, B, or C, rotate the large rotary switch clockwise to change the brightness from low to high and rotate it counterclockwise to change the brightness from high to low. Rotate it to the counterclockwise stop to turn off the lantern.
• In Modes A and C, rotate the small rotary switch clockwise to change the color temperature from cold to warm and rotate it counterclockwise to change the color temperature from warm to cold.

Intelligent Memory Circuit

The lantern automatically memorizes the previously used mode, excluding the Warning mode. When turned on again, the previously used mode will be recalled.

The lantern automatically memorizes the previously used output of the Warning mode.  When turned on again in Warning mode, the previously used output of the Warning mode will be recalled.

The lantern memorizes the last selected color temperature of Floodlight mode. When turned on again in Floodlight mode, the previously selected color temperature will be recalled.

Note: 

• The lantern doesn’t memorize the last selected brightness level. When turned on again, the lantern will activate on the Low output.
• If the small rotary switch is rotated after the lantern is turned off, then the lantern will not recall the previously selected color temperature when turned on again.

Battery Specifications

Warning:

*21700 Li-ion batteries are powerful cells designed for commercial applications and must be treated with caution and handled with care. Using low-quality batteries or mishandling batteries (such as short-circuiting or overheating) could lead to combustion and jeopardize the safety of users and property. Any adverse effects resulting from the use of low-quality batteries are not covered by any Fenix warranty or liability. Using quality batteries with circuit protection will reduce the potential for combustion or explosion.

Battery Replacement

Pull up the pulling ring at the lantern bottom and unscrew it counterclockwise to open the battery cover. Insert the batteries with the cathode side (-) towards the inside, then screw the battery cover back on.

Charging

1. Open the anti-dust cover and connect the USB Type-C end of the charging cable to the lantern.
2. When charging, the battery level indicators will flash from left to right to display the charging status.
3. The four indicators will be constant-on after charging is completed.

Note: 

• When charging, the maximum brightness level of the lantern is 500 lumens.
• With the lantern turned off, the normal charging time is at least approximately 3 hours from depleted to fully charged with a maximum charging power of 18 W.
• Once charging is completed, be sure to unplug the charging cable and close the anti-dust cover.

Power Bank Function

• Open the anti-dust cover and connect the USB-C end or the USB-A end of the charging cable to the light.
• When discharging, the battery level indicators will flash from right to left to display the discharging status.
• When the battery level is lower than 3 V, the lantern will automatically stop discharging.

Note: 

• The lantern can be operated while discharging.
• Fast charging protocols supported include: USB-C: PD3.0/PD2.0/QC3.0/QC2.0; USB-A: QC3.0/QC2.0.
• Discharge performance: If the discharge output is 5 V, then the maximum discharge current is 3 A; if the discharge output is 9 V, then the maximum discharge current is 2 A; if the discharge output is 12 V, then the maximum discharge current is 1.5 A.
• The USB-A and USB-C ports can discharge simultaneously.
• The USB-A port cannot discharge while the lantern is being recharged via the USB-C port.

Battery Level Indication

With the lantern turned off, single click the electronic switch to check the battery status, the indicator(s) will last for 3 seconds.

Each time the lantern is turned on, the indicator(s) will show the current battery level and will last for 3 seconds.

• Four lights on: 100% – 80%
• Three lights on: 80% – 60%
• Two lights on: 60% – 40%
• One light on: 40% – 20%
• One light flashes: 20% – 1%

Intelligent Overheat Protection

The lantern will accumulate a lot of heat when used for extended periods. When the lantern reaches a temperature of 54°C/129.2°F or above, it will automatically step down a few lumens to reduce the temperature. When the temperature drops below 54°C/129.2°F, the lantern will gradually recall the preset output level.

Low-voltage Warning

When the voltage level drops below the preset level, one battery level indicator blinks to remind users to recharge or replace the batteries in a timely manner. To ensure normal use, the lantern will not turn off automatically and will work till the battery level runs out.

Usage and Maintenance

• Disassembling the sealed parts of the lantern can cause damage to the lantern and will void the warranty.
• Fenix recommends using excellent quality batteries.
• If the lantern will not be used for an extended period, remove the batteries, or the lantern could be damaged by electrolyte leakage.
• Recharge a stored lantern every three months to maintain optimum performance of the batteries.
• The lantern may flicker, shine intermittently or even fail to illuminate for the following reasons:

  A: Poor battery level.

  Solution: Recharge or replace the batteries.

  B: The contact or contact point of the batteries or lantern is dirty.

  Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.

Warning

• Do NOT place this lantern in the reach of children!
• Do NOT shine the lantern directly into the eyes of anyone!
• Do NOT place the lantern near flammable objects, high temperatures can cause objects to overheat and become flammable/ignite!
• Do NOT use the lantern in inappropriate ways such as holding the unit in your mouth, doing so could cause serious personal injury or death if the lantern or internal batteries fail!
• This lantern will accumulate a significant amount of heat while operating, resulting in a high temperature of the lantern shell. Pay close attention to avoid burns.
• Remove the batteries to prevent accidental activation when the lantern is placed in a closed and flammable environment such as pockets and backpacks!
• The LEDs of this lantern are not replaceable; so the whole lantern will need to be replaced when any one of the LEDs reaches the end of its lifespan.
