one Switch Usage Instructions
1. The battery should have the positive terminal facing inward (towards the lamp head) and the negative terminal facing outward (at the tail).
2. The switch is at the rear. The switch function is the switch function. Pressing the switch lightly is the dimming function.
two Circuit Board Usage Instructions
The flashlights in our store adopt advanced voltage stabilization and constant current technology, which can effectively meet the requirements of LED flashlights for voltage stabilization and constant current.
2. Special Note: a. Do not use under overvoltage. The voltage should not exceed 4.2V. b. Keep the battery upright facing forward. Do not place it in reverse, otherwise the battery will burn out. c. Pay attention to controlling the temperature changes of the flashlight to ensure heat dissipation. d. Non-professionals are not allowed to open the circuit board.
3. Warranty Description: Open or processed circuit boards are no longer covered by the warranty.
Three Lithium Battery Usage Instructions
1. Characteristics of lithium batteries: The charging methods of lithium batteries are different from those of mobile phone batteries. Lithium batteries have no memory effect and can be charged at any time. Do not overcharge or overdischarge them.
2. The first charge should last at least 6 hours. After that, it's fine as long as the green light on the charger is on. There's no need to overcharge.
3. Special reminder: Use a charger with "three-proof" features that prevent overcharging, reverse connection, and short circuit.
4. If the battery is not used for a long time, it should be fully charged and stored. It is normal to charge and discharge it once every three months or so.
Four Instructions for using the flashlight
When using a flashlight, select it based on the voltage and battery requirements of the flashlight. Do not use it randomly to prevent the circuit board from being burned out. Do not use batteries of different models and voltages simultaneously.
2. During use, when the brightness of the flashlight changes significantly, turn it off to prevent over-discharging the battery.
3. Heat dissipation tips: During the use of the flashlight, ensure proper heat dissipation. It is strongly recommended that when the battery is fully charged, the second gear be used first. This can extend the lifespan of the flashlight's lamp head and battery. Do not shine the flashlight directly into people's eyes. It is extremely bright and dazzling, which may affect eyesight, especially for children.
Five Fault repair
1. Check the battery: Make sure the battery is charged and installed in the correct direction. Do not use batteries of different brands, and do not mix new and old batteries.
2. Check the tail cover: Ensure that the switch is tightened and in good contact, guarantee that the copper column of the tail cover is in good contact with the metal sheet of the tail cover pressure ring, and pay attention to whether the lamp head is loose.
