Under Strobe mode, single-click the side switch to cycle through Strobe→SOS.

Intelligent Memory Circuit
The flashlight memorizes the last-used brightness level in the General mode, but not Strobe and SOS. The next time you turn on the flashlight, it will activate the last brightness level you selected.

Over-heat Protection
The flashlight will accumulate a lot of heat when it is working at Turbo and High brightness level. When it works at Turbo for 3 minutes or at High for 30 minutes, the flashlight will automatically downshift to lower output to prevent the light from overheating. If the Turbo or High output is needed, please reset it again. But the flashlight could be damaged or the normal service life would be shortened because of continuous use like this.

Low-voltage Warning Function
If low voltage is detected, the flashlight is programmed to downshift to a lower brightness level until to Eco brightness level. When this happens at Eco 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 until the battery runs out completely.
