A. Switch instructions

1, the battery positive towards (lamp side), negative outward (tail). 2,
switch in the rear, switch function Cheng'an switch function, press the switch is dimming function.
two. Circuit board instructions for use
1, the torch using advanced voltage constant current technology can effectively solve the LED flashlight on the voltage constant current requirements.
2, special tips: A. do not use of overpressure and voltage not more than 4.2V battery B. root is toward the front, not inverted, otherwise it will burn in C. note torch temperature change control and guarantee of non professional personnel do not open the circuit board
radiating D. for 3, warranty Description: open or treated circuit board is no longer under warranty.
three. Lithium battery instructions
1, lithium battery characteristics: lithium batteries and mobile phone battery charging in a completely different way; lithium battery no memory can be filled at any time, don't be too charge and discharge.
2, the first charge 6 hours at least, then according to the charger green light can be, will not overcharge.
3, in particular, prompt to use anti overcharge, anti reverse connection, short circuit proof "three defenses" charger;
4, for a long time do not use the battery, the will be filled with electricity saving and normal in about three months to charge and discharge a;
four. The use of torch
1, flashlight when in use, according to the requirement of the torch to the voltage of the battery and, should not be used indiscriminately, to prevent the burned circuit board, different types, different voltage battery don't and.
2, in use, when the torch brightness changes to turn off the flashlight, to prevent over discharge of the battery. 3,
cooling techniques: the torch in the use process, to ensure the heat dissipation. Strongly urge the battery is full of electricity, it is best to use the second gear, so as to let the torch lamp cap and a battery and prolong the service life of the product! The torch of light will not direct people's eyes, bright dazzling, so as not to affect the vision, especially in children.
five. Troubleshooting
1, check the battery: to ensure that the battery power and in the correct direction to install the battery, do not use different brands of batteries, the old and new batteries do not mix.
2, check the tail cap switch has been tightening: to ensure good contact and ensure the end cap and the end cap pressure ring copper sheet metal contact is good, pay attention to whether the loosening of the lamp
