A. Switch instructions
1. The battery is in the front (the end of the lamp), and the cathode is outward (tail).
2. The switch is in the tail, and the switch function is switched on and off. The light switch is the dimming function.
2. Circuit board instructions.
1. The torch adopts advanced steady flow technology, which can effectively solve the requirements of the LED flashlight on the steady current.
2, special tips: a. do not use the overpressure, not more than 4.2 V voltage b. batteries are roots in the front, not the inverted, otherwise will burn plate c. Pay attention to control the flashlight temperature change, guarantee the cooling d. non-professional workers do not open the circuit board
3. Warranty description: open or process the circuit board no longer warranty scope.
3. Lithium battery instructions.
1. Features of lithium battery: the charging mode of lithium battery and cell phone battery is completely different; Lithium battery has no memory, can be charged at any time, do not overcharge.
2. The first charge of 6 hours is the minimum, and after that, according to the green light of the charger, it will be ok.
3. Special prompt should be used to use the \"three-proof\" charger that has anti-overcharge, anti-reverse and short-circuit protection;
4. The battery should be stored for a long time without using the battery, and the battery should be charged and discharged once again in about three months.
Four. Instructions for the use of torches.
1. When the flashlight is in use, select the voltage and battery according to the flashlight, and do not use it in a random way, so as to prevent the burning of the circuit board, and the battery of different models and voltages should not be used at the same time.
2. In use, the flashlight should be turned off when the brightness of the flashlight changes significantly, so as to prevent the battery from being released.
3. Heat dissipation technique: in the process of using the flashlight, ensure the heat dissipation. When the battery is fully charged, it is better to use second gear, so that the lamp holder and the battery can extend the product life. Do not shine the flashlight directly into the eyes of the eyes, super bright glare, so as not to affect the vision, especially children.
Five. troubleshooting
1. Check the battery: make sure that the battery has electricity and the battery is installed in the correct direction, and the battery of different brands should not be used, and the old and new batteries should not be mixed.
2. Check the tail cover: make sure that the switch is tightened and the contact is good, ensure that the copper column of the tail cover is in good contact with the metal plate of the end cover, and notice whether the lamp head is loose.
