one Switch instructions
1, the battery is positive (lamp head side), negative (tail).
2. The switch is at the end, the switch function is the switch function, and the light switch is the dimming function.
two Circuit board instructions
1. Our flashlight adopts advanced constant current technology of constant voltage, which can effectively solve the requirements of LED flashlight for constant voltage.
2. Special note: A. Do not use with overvoltage and the voltage shall not exceed 4.2V; B. Do not reverse position the battery root forward, otherwise it will burn the plate; C. Pay attention to control the temperature change of the torch to ensure heat dissipation; D. Do not open the circuit board for non-professionals.
3. Warranty description: after opening or treating the circuit board, the warranty scope is no longer.
3. Lithium battery instructions
1. Characteristics of lithium battery: The charging mode of lithium battery and mobile phone battery is different; Lithium battery has no memory, can be charged at any time, do not overcharge put;
2. First charge for 6 hours at least, then according to the charger green light is ok, there is no need to overcharge;
3. In particular, it is suggested to use the \"three-proof\" charger with anti-overcharge, anti-reverse connection and anti-short circuit;
4. If the battery is not used for a long time, the battery should be fully charged and stored, and normally charged and discharged again in about three months;
Four. Directions for flashlight use
1, the flashlight in use, according to the voltage and battery requirements, do not misuse, in order to prevent burning circuit board, different models, different voltage of the battery do not use at the same time.
2, in use, when the brightness of the flashlight obvious change to turn off the flashlight, to prevent the battery overput.
3, heat dissipation skills: torch in the use of the process, to ensure the heat dissipation. It is strongly required that when the battery is fully charged, first use the second gear, so that the lamp holder and the battery can be extended product life; Do not direct the flashlight light into people's eyes, super bright dazzling, so as not to affect the vision, especially children.
Five. troubleshooting
1. Check the battery: make sure that the battery is charged and installed in the correct direction. Do not use different brands of batteries, and do not mix old and new batteries.
2. Check the tail cover: ensure that the switch has been 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 tail cover gland, and pay attention to whether the lamp holder is loose.
