1. Switch Usage Instructions
1. The battery is positioned with the positive terminal facing in (towards the bulb end) and the negative terminal facing out (towards the tail end).
2. The switch is located at the tail, and the switch function is the same as the safety switch. Pressing lightly on the switch is the dimming function.
Section 2: Circuit Board Usage Instructions
1. 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 Notes: a. Please do not use the product under excessive pressure; the voltage should not exceed 4.2V; b. The positive terminal of the battery should face forward, do not reverse it, or it may cause damage to the board; c. Pay attention to the change of the flashlight temperature to ensure heat dissipation; d. Please do not open the circuit board unless you are a professional person.。
3. Warranty Statement: The warranty does not cover opened or handled circuit boards.
Section 3: Lithium Battery Usage Instructions
1. Features of Lithium Batteries: Lithium batteries have a different charging method from mobile phone batteries; Lithium batteries have no memory effect, they can be charged at any time, and there is no need to overcharge or overdischarge.
2. Charge for at least 6 hours the first time, and then it's enough as soon as the charger's green light turns on. There's no need to overcharge.
3. Special Note: Use a "Three Defense" charger with overcharge protection, reverse connection protection, and short circuit protection.
4. If the battery is not used for a long time, it should be fully charged and stored. It is recommended to charge and discharge it again every three months or so.
Section 4: Instructions for Using Torches
1. When using the flashlight, choose it based on the requirements of the flashlight for voltage and batteries. Do not use it randomly to prevent burning out the circuit board. Do not use batteries of different models and voltages at the same time.
2. When using the flashlight, turn it off if the brightness significantly changes to prevent the battery from being over-discharged.
3. Heat dissipation tips: Ensure heat dissipation during the use of the flashlight. It is strongly recommended to start with the second level when the battery is fully charged to extend the life of the flashlight head and the battery. Do not direct the flashlight beam into someone's eyes, as the bright light can be blinding and may affect vision, especially for children.
Fault Inspection and Maintenance
1. Check the battery: Ensure that the battery is charged and installed in the correct direction. Do not use batteries from 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, and that the metal contact between the tail cover's copper column and the press ring is good. Also, ensure that the lamp head is not loose.
