Instructions for Use of strong light flashlight:

1. Instructions for Use of the switch
1. The battery is the positive pole facing inside (the side of the lamp holder), and the negative pole facing outside (the tail).
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 it over pressure, and the voltage should not exceed 4.2V B. The battery is facing forward, do not set it in reverse, otherwise it will burn plate 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
1. This flashlight use a battery mainly 18650 lithium batteries.
2. Features of lithium battery: the charging method of lithium battery is completely different from that of mobile phone battery; Lithium battery has no memory and can be charged at any time, and should not be overcharged and overdischarged.
3. It takes at least 6 hours to charge for the first time, and then it will be OK to turn on the green light according to the charger. No charge is required.
4. When the natural discharge rate of lithium battery is not in use, it releases 1% or less of its charge on a big date every day. Although it is slow, it prevents it from being placed for too long.
5. Pay attention to the waterproof, period-proof and fall-proof of the battery.
6. Special tips: use a "three-proof" charger with anti-overcharge, anti-reverse connection, and anti-short circuit;
7. If you do not use the battery for a long time, you should fully store the battery and charge it once again in about three months normally;
8. Warranty description: the battery is no longer covered after it leaves the factory.
IV. Instructions for Use of flashlight
1 torch, choose according to the requirements of the flashlight on voltage and battery. Do not use it indiscriminately to prevent the circuit board from being burnt out. Do not use batteries of different models and voltages at the same time.
2. In use, when the brightness of the flashlight changes significantly, turn off torch to prevent the battery from being over-discharged.
3. Heat dissipation skills: ensure heat dissipation during the use of the flashlight. When the battery is fully charged, it is strongly required to use the second gear first, so that the lamp holder and battery of the flashlight can prolong the service life of the product! Holding torch tightly by hand is the heat dissipation of ten thousand type; It is suggested that when it is lit, it should be timely dissipated or turned off according to the heating condition of the flashlight, and then lit up after the temperature drops, so as to dissipate heat.
4. Strengthen prevention according to the instructions of flashlight on waterproof and shockproof.
5. Keep the inner wall of the lamp Cup clean, and never wipe it with hands or harder objects; The fingerprints on the lens can be gently wiped with cotton swabs lens cleaner.
6. Do not direct the flashlight to people's eyes, which is super bright and dazzling, so as not to affect eyesight, especially children.
7. If you do not use the flashlight for a long time, please take out the battery (one month or longer) to avoid chemical corrosion.
V. Protection instructions
1. Do not contact torch with sunlight, water, chemicals and corrosive gases for a long time to avoid damaging the protective layer of the flashlight.
2. In order to keep the "0" ring and thread spinning smooth, wipe Vaseline oil on its surface 2-3 times a year.
VI. Troubleshooting
1. Check the battery: make sure that the battery has electricity and the battery is installed in the correct direction. Batteries of different brands cannot be used. New and old batteries cannot be mixed.
2. Check tail hood: make sure that the switch is tightened and in good contact, and ensure that the tail Hood copper cylinder is in good contact with the tail Hood pressure ring metal sheet.
3. Pay attention to whether the lamp holder is loose.
