Operating Instructions
Switches: General switch — for on/off and output selection on General mode. Functional switch — for on/off and output selection on Functional mode.
On/off: Press and hold either of the switches for 0.5 seconds to turn on/off the lamp.
Output Selection: General mode — single click the general switch to cycle through Low → Med → High → Turbo of Spotlight. Functional mode — single click the functional switch to cycle through Low → Med → High → Red Light → Red Flash.
Intelligent Memory Circuit: The headlamp memorizes the last selected output. When turned on again, the previously used output will be recalled.
Lockout Function
Lock: when the lamp is switched off, press and hold either of the two switches, or simultaneously press the two switches for 3 seconds, the lamp will blink red three times to indicate locked status.
Unlock: when the lamp is locked, simultaneously press the two switches for 3 seconds, the lamp will be activated with 3 one-second red blinks and activated on Red Light. In locked status, clicking or pressing the switches will activate 3 one-second red blinks to indicate locked status.
If the headlamp is turned off on Turbo level of Spotlight mode, when turned on again, it will be activated on High output of Spotlight mode.

1. It is strictly prohibited to charge non-rechargeable batteries via the headlamp. 2. Recharge a stored headlamp every four months to maintain optimal Li-polymer battery performance. 3. If the lamp will not be used for an extended period, remove the AA batteries from the lamp in case of damage by electrolyte leakage.
Intelligent Overheat Protection
The lamp will accumulate a lot of heat when used at relatively high output levels for extended periods. When the lamp reaches a temperature of 65°C or above, the lamp will automatically step down a few lumens to reduce the temperature. When the temperature drops below 65°C, it will then allow the user the reselection of the modes.
Low-Voltage Warning
When the voltage level drops below the preset level, the headlamp is programmed to downshift to a lower brightness level until Low output is reached. When this happens in Low output mode, the battery level indicator blinks to remind you to timely recharge or replace the battery.
Note: this only works with Fenix ARB-LP3000 Li-polymer battery.
Headband Assembly
The headband is factory assembled by default. Adjust the headband by sliding the buckle to required length.
Usage and Maintenance
- Disassembling the sealed head can cause damage to the lamp and will void the warranty.
- Fenix recommends using an excellent quality Fenix battery.
- If the lamp will not be used for an extended period, remove the battery, or the lamp could be damaged by electrolyte leakage.
- Lock the lamp or take out the battery to prevent accidental activation during storage or transportation.
- Periodic cleaning of the battery contacts improves the lamp's performance as dirty contacts may cause the lamp to flicker, shine intermittently or even fail to illuminate for the following reasons: A) The battery needs replacing — replace battery (ensure battery is inserted according to the manufacturer's specifications). B) The contact point or contact of the battery or headlamp is dirty — clean the contact points with a cotton swab soaked in rubbing alcohol. If the above methods don't work, please contact the distributor.
Battery Replacement
- Pull latch to open the battery cover.
- Insert the battery/batteries in accordance with the polarity marks.
- Replace the battery cover and fasten the latch.
Charging
- The included Li-polymer battery pack can be charged via the headlamp. It is strictly prohibited to charge non-rechargeable AA (Ni-MH/Alkaline) batteries via the headlamp.
- Uncover the anti-dust cap of the battery case and plug the USB Type-C side of the charging cable into the charging port of the battery case.
- The indicator on the battery case will display red while charging, and will turn to green when fully charged.
- Replace the anti-dust cap to ensure waterproof and dustproof ability.
- The normal charging time of the Fenix ARB-LP3000 Li-polymer battery is about 3 hours with the lamp being switched off.
Battery Level Indication
With the lamp switched off, single click either of the switches to check the battery status; the indicator 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%
Note: this only works with Fenix ARB-LP3000 Li-polymer battery.
