一. Instructions for use of the switch
1. The positive pole of the battery faces inward (on the lamp head side) and the negative pole faces outward (at the tail).
2. The switch is at the tail. The switch function is the switch function. Pressing the switch lightly is the dimming function.

 

二. Instructions for use of the circuit board
1. Our flashlight adopts advanced voltage-stabilizing and constant-current technology, which can effectively solve the requirements of LED flashlights for voltage-stabilizing and constant-current.
2. Special tips: a. Do not use overvoltage, the voltage should not exceed 4.2V b. The positive root of the battery faces forward, do not reverse it, otherwise it will burn the board c. Pay attention to control the temperature change of the flashlight to ensure heat dissipation d. Non-professionals should not open the circuit board
3. Warranty description: Opening or handling the circuit board is no longer covered by the warranty.

 

三. Instructions for use of lithium batteries
1. Features of lithium batteries: The charging method of lithium batteries is completely different from that of mobile phone batteries; lithium batteries have no memory and can be charged at any time. Do not overcharge or over-discharge.
2. The first charge is less than 6 hours. After that, just turn on the green light of the charger. There is no need to overcharge.
3. Special reminder to use a "three-proof" charger that is anti-overcharge, anti-reverse connection, and anti-short circuit;
4. If the battery is not used for a long time, it should be fully charged and stored. Normally, it should be charged and discharged once in about three months.

 

四. Instructions for the use of the flashlight
1. When using the flashlight, choose according to the flashlight's requirements for voltage and battery. Do not use it indiscriminately to prevent the circuit board from being burned. Batteries of different models and voltages should not be used at the same time.
2. During use, turn off the flashlight when the brightness of the flashlight changes significantly to prevent over-discharge of the battery.
3. Heat dissipation tips: During the use of the flashlight, ensure heat dissipation. It is strongly required that when the battery is fully charged, it is best to use the second gear first, so that the flashlight head and battery can extend the product life! The flashlight light cannot be directly shot into people's eyes. It is super bright and dazzling to avoid affecting vision, especially children.

 

五. Fault troubleshooting
1. Check the battery: make sure the battery is charged and installed in the correct direction. Do not use batteries of different brands, and do not mix old and new batteries.
2. Check the tail cap: make sure the switch is tightened and in good contact, ensure that the copper column of the tail cap is in good contact with the metal sheet of the tail cap pressure ring, and pay attention to whether the lamp head is loose
