2. The switch is at the tail, the switch function bearing switch is the switch function, and the light switch is the dimming function.
II. Circuit board instructions
1 torch adopts advanced constant voltage and constant current technology, which can effectively solve the requirement of constant voltage and constant current for LED torch.
2. Special tips: a. Do not use over pressure, the voltage should not exceed 4.2V; B. The battery is facing forward, do not set it in reverse, otherwise it will burn the board; c. Pay attention to controlling the change of flashlight temperature to ensure heat dissipation; d. Do not open the circuit board for non-professionals.
3. Warranty description: no longer covered by warranty after opening or handling the circuit board.
III. Lithium battery instructions
