Operation instructions:

First, install the battery correctly, with the cathode of the battery facing the direction of the light head. This flashlight has reverse connection protection. Even if it is installed incorrectly, the flashlight will not be damaged, but it will not work. Please check the battery in time.

After installing the battery, half-press the tail switch button once and do not release it to turn on the high power mode. Release it to turn it off. At this time, half-press the switch again and do not release it to switch to low power mode. Repeat this operation, and the flashlight will cycle between high and low power. When any power is turned on, press the switch hard and the "click" sound will keep this mode running continuously. Press the switch again to turn off the flashlight.

During use, when the battery power is low, the flashlight light will flash as a reminder. Please charge the battery in time.
