Instructions for use
1. The battery is positive facing inward(Over the lamp holder), The negative electrode faces outward(Tail).
2. The switch is at the rear, the switch function is the switch function, and the lightly press the switch is the dimming function.
two. Circuit board instructions
1. Our torch adopts advanced voltage-stabilized and constant-current technology, which can effectively solve the requirements of LED torches for voltage-stabilized and constant current.
2. Special tips: a. Do not use overvoltage, and the voltage should not exceed 4.2V. b. The positive root of the battery is facing forward, and do not reverse, otherwise it will burn the board. c. Pay attention to the temperature change of the torch to ensure heat dissipation. d. Non-professionals Do not open the circuit board
3. Warranty description: Opened or processed circuit boards are no longer covered by the warranty.
three. Lithium battery instructions
1. Lithium battery characteristics: Lithium batteries and mobile phone batteries have completely different charging methods; lithium batteries have no memory and can be charged at any time, do not overcharge or discharge.
2. The first charge is 6 hours at least, and then the green light on the charger will be on. There is no need to overcharge.
3. Special reminder to use “three-proof”charger with 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 again in about three months;
four. Instructions for use of torch
1. When the torch is in use, choose according to the voltage and battery requirements of the torch. Do not use it indiscriminately to prevent the circuit board from burning. Do not use batteries of different models and voltages at the same time.
2. In use, turn off the torch when the brightness of the torch changes significantly to prevent over-discharge of the battery.
3. Heat dissipation skills: ensure heat dissipation during the use of the flashlight. When the battery is strongly required to be fully charged, it is best to use the second gear first, so that the lamp holder and battery of the flashlight can be extended product life! Do not direct the light of the flashlight into the eyes of people. It is super bright and dazzling, so as not to affect the eyesight, especially for children.
Fives. Troubleshooting
1. Check the battery: make sure that the battery is powered and install the battery in the correct direction. Do not use batteries of different brands, and do not mix old and new batteries.
2. Check the tail cover: make sure that the switch has been tightened and the contact is good, and the copper pillar of the tail cover is in good contact with the metal sheet of the tail cover pressing ring. Pay attention to whether the lamp cap is loose.
