Battery Specifications  

*Do not mix batteries of different brands, sizes, capacities or types. Doing so may cause damage to the lamp or to the batteries being used.

*Only use the recommended or usable batteries mentioned in this user manual. 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. It is recommended to use a Fenix ARB-LP1900 battery.

Battery Replacement

Charging

1. Uncover the anti-dust cap and plug the USB Type-C side of the charging cable into the charging port of the lamp.
2. When charging, the indicators will flash from left to right to display the charging status. The four indicators will be constant-on after charging is completed.
3. With the lamp switched off, the normal charging time of using a Fenix ARB-LP1900 battery is about 3 hours from depleted to fully charged with a 5 V/1 A or above charging adapter.

Note:

1. Only Low output can be operated while charging.
2. Recharge a stored lamp every four months to maintain the optimum performance of the battery.

Battery level indication

With the lamp switched off, single click either switch to check the battery status. Single click once again the indicator(s) will go out immediately, or without any operation the indicator(s) will last for 3 seconds. Each time the light is turned on, the indicator(s) will show the 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%

*Note: This feature only works with a Fenix ARB-LP1900 battery.

Intelligent Overheat Protection            

The lamp will accumulate a lot of heat when used at high output levels for extended periods. When the lamp reaches a temperature of 55°C/131°F or above, it will automatically step down a few lumens to reduce the temperature. When the temperature drops below 55°C/131°F, the lamp will gradually recall the preset output level.

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, one of the battery level indicators blinks to remind you to recharge or replace the battery.

*Note: This feature only works with a Fenix ARB-LP1900 battery.

Headband Assembly 

Notice: The headband is factory assembled and ready to use right out of the package.

Rotate the dial clockwise to tighten the headband, and rotate the dial anticlockwise to loosen the headband. After loosening the headband to its maximum length, rotate the dial in either direction to tighten it.
