Intelligent Memory Circuit

The light memorizes the last selected brightness level on general mode. When turned on again the previously used brightness level will be recalled.

Overheat Protection

The light will accumulate a lot of heat when used on Turbo output level for extended periods. The light will automatically step down by a few lumens to reduce temperature. When the temperature is reduced, the Turbo output level can be reselected.

Low-voltage Warning

When the voltage level drops below the preset level, the flashlight is programmed to downshift to a lower brightness level until Low output is reached. When this happens in Low output mode, the flashlight blinks three times every five minutes to remind you to replace the battery. To ensure normal use, the flashlight will not turn off automatically and will work till the battery protection activates. Note: This only works with 16340 Li-ion battery.

Battery Replacement

Unscrew the tail cap to insert the battery with the anode side (+) towards the light head, then screw the light head back on.

Usage and Maintenance

• Disassembling the sealed head can cause damage to the light and will void the warranty.
