light flashlight instructions for use

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 in the tail/barrel body, the switch function is the switch function, and the light-adjusting function is the light-pressing switch.

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. It should be noted that the control torch as well as the variation of the heat diffusion 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. Most torch batteries mainly use 18650 and 16340 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. Charge for at least 6 hours for the first time, and then 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. Torch instructions for use

1, the torch in use according to the torch on the battery and battery voltage to select, don't mess with, to prevent burn out circuit board, different types, different voltage of battery don't use at the same time.

2, in use, when the torch of the luminance change significantly when to close the torch to prevent battery discharge.

3, heat dissipation techniques: Torch in the use of the process, in the warehouse and you need to ensure the cooling. Urge the battery is fully charged, first second and allow torch of the lamp holder and battery product longevity! With hand torch is good heat dissipation tens; Recommendations placed lit according to the torch of the heating condition of the timely heat dissipation or off until the temperature down after the light so that the heat dissipation.

4, for the torch on the waterproof, shockproof and note by the prevention.

5. Keep the inner wall of the lamp Cup clean, and do not wipe it with hands or harder objects; The fingerprints on the clear lens can be gently wiped with cotton swab lens cleaner.

6, the torch light direct the human eye, so as not to affect the vision, especially children.

7, if a long time does not use torch please remove the battery (a month or longer), to avoid the occurrence of chemical corrosion.

V. Protection description

1, do not torch long-term with sunlight, water, chemicals, and corrosive gases such as contact, to avoid damage to the torch protective layer.

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.
