Instructions for use of strong light flashlights

I. Instructions for use of switches

1. The positive pole of the battery faces inward (the lamp head side) and the negative pole faces outward (the tail).

2. The switch is at the tail. The switch function is the switch function. Pressing the switch lightly is the dimming function.

II. Circuit board instructions

1. The flashlight adopts advanced voltage-stabilizing constant current technology, which can effectively solve the requirements of LED flashlights for voltage-stabilizing constant current.

2. Special tips: a. Do not use overvoltage, the voltage should not exceed 4.2V b. The battery should face forward, do not reverse, otherwise it will burn the board c. Pay attention to the change of the flashlight temperature to ensure heat dissipation d. Non-professionals should not open the circuit board

3. Warranty description: The warranty is no longer valid if the circuit board has been opened or handled.

III. Lithium battery instructions

1. Most flashlight batteries mainly use 18650 and 16340 lithium batteries.

2. Characteristics 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.

3. The first charge takes at least 6 hours, and then the green light on the charger will be on. No need to overcharge.

4. The natural discharge rate of lithium batteries will release about 1% or less of its charge every day when not in use. Although it is slow, it is necessary to prevent it from being placed for too long.

5. Pay attention to the waterproof, anti-expiration, and anti-fall of the battery.

6. Special reminder to use a "three-proof" charger that is anti-overcharge, anti-reverse connection, and anti-short circuit;

7. If the battery is not used for a long time, it should be fully charged and stored, and normally it should be charged and discharged once every three months;

8. Warranty description: The battery is no longer covered by the warranty after leaving the factory.

IV. Instructions for the use of flashlights

1. When using a 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. When the brightness of the flashlight changes significantly during use, turn off the flashlight to prevent over-discharge of the battery.

3. Heat dissipation tips: When the flashlight is in use, ensure heat dissipation. It is strongly recommended to use the second gear when the battery is fully charged, so that the flashlight head and battery can be extended! Holding the flashlight tightly with your hand is the best way to dissipate heat; it is recommended to dissipate heat or turn it off in time according to the heat generation of the flashlight when it is lit, and then light it again after the temperature drops to dissipate heat.

4. Strengthen prevention against the instructions of the flashlight on waterproofness and shockproofness.

5. Keep the inner wall of the lamp cup clean and do not wipe it with your hands or hard objects; to clean fingerprints on the lens, you can use a cotton swab dipped in lens cleaner to gently wipe it.

6. Do not shine the flashlight directly into people's eyes to avoid affecting vision, especially children.

7. If you do not use the flashlight for a long time (one month or longer), please remove the battery to avoid chemical corrosion.

V. Protection Instructions

1. Do not expose the flashlight to sunlight, water, chemicals, corrosive gases, etc. for a long time to avoid damaging the flashlight's protective layer.

2. To keep the "0" ring and thread rotating smoothly, apply vaseline oil on their surface 2-3 times a year.
