One. Switch instructions
1. The battery has the positive pole facing inward (the lamp holder side) and the negative pole facing 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 flashlight 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 over discharge.
2. The first charge is at least 6 hours, and then the green light on the charger will be on. There is no need to overcharge.
3. Special reminder to use the "three-proof" charger with anti-overcharge, anti-reverse connection and anti-short circuit;
4. If the battery is not used for a long time, the battery should be fully charged and stored, and normally charge and discharge again in about three months;
four. Instructions for using flashlight
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 torch can extend the life of the product! Do not direct the light of the torch into human eyes. It is super bright and dazzling, so as not to affect eyesight, especially children.
Fives. Troubleshooting
1. Check the battery: make sure that 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 cover: make sure the switch has been tightened and in good contact, ensure that the copper pillar of the tail cover is in good contact with the metal sheet of the tail cover pressing ring, and pay attention to whether the lamp cap is loose.
