*This feature only works with a recommended battery.

INTELLIGENT OVERHEAT PROTECTION

The light will accumulate a lot of heat when used at high output levels for extended periods. When the light reaches a temperature of 60°C/140°F or above, the light will automatically step down a few lumens to reduce the temperature. When the temperature drops below 60°C/140°F, the light automatically recalls the previously used output level.

LOW VOLTAGE WARNING

When the voltage level drops below 3.0 V, the flashlight is programmed to downshift to a lower brightness level until Eco output is reached. When this happens in Eco output, the battery level icon on the OLED smart display flashes to remind you to replace or recharge the battery. To ensure normal use, the flashlight will not turn off automatically and will work till the battery level runs out.

*This feature only works with a recommended battery.

USAGE AND MAINTENANCE

• Disassembling the sealed head can cause damage to the light and will void the warranty.
• Fenix recommends using an excellent quality battery.
