ⅡCircuit board instructions:
1. Our flashlight using advanced constant voltage constant current technology, can effectively solve the LED flashlight on the constant current requirements.
2. Special Note:
A. Do not overpressure use, the voltage should not exceed 4.2V
B. The battery is facing forward, do not reverse, otherwise it will burn board
C. Pay attention to control the flashlight temperature changes, to ensure heat
D. Do not open the circuit board for non-professionals
Ⅲ Lithium battery instructions:
1. Lithium battery features: lithium battery and cell phone battery charging method is completely different; lithium battery is not memory, can always charge, do not overcharge and over discharge.
2. The first charge of 6 hours at least, after the green light on the charger can be lit, and no charge overcharge.
3. Special tips to use anti-overcharge, anti-reverse, anti-short circuit of the "three anti" charger;
4. Do not use the battery for a long time, should be full of electricity to save, normally in about three months and then charge and discharge once.
Ⅳ Flashlight instructions
1. Flashlight in use, according to the flashlight on the voltage and battery requirements, do not indiscriminate use, to prevent burning bad circuit boards, different models, different voltage batteries do not use at the same time.
2. In use, when theFlashlight of the brightness changes significantly to turn off the Flashlight to prevent the battery over discharge.
3. Thermal Tips: Flashlight in the use of the process, to ensure that heat. Strongly require the battery is fully charged, it is best to use the second gear, so that the Flashlight of the lamp and the battery can be extended product life! Can not direct the Flashlight light eyes, super bright glare, so as not to affect vision, especially children.
Ⅴ Troubleshooting
