Thank you, good day Specification: Material: Aluminum alloy Light source: LED * XPE + COB 3 Lighting modes: Strong light XPE, Low light XPE, Strong cob light. Light Color: White Color of The hull: black Battery power: 14500 Built-in 600 mAh battery Switch: push button switch Dimensions: 2 cm x 9.2 cm x 2.5 cm / 0.79 inches x 3.62 inches x 0.98 inches Weight: 59 grams The package includes: 1 LED flashlight (with battery) 1 x micro USB charging cable 1 x Storage box one. Switching instructions 1. The positive pole of the battery is inward (on the side of the pellet of the lamp) and the negative pole to the outside (tail). 2. The switch is on the back, the switch function is the function of the switch and a slight pressure on the switch is the dimension function. Two. Description of the printed circuit 1. Our flashlight adopts advanced voltage stabilization and DC stabilization technology, which can LED flashlights require constant voltage and current. 2. Special reminder: a. Do not use overvoltage and voltage should not exceed 4,2VB. The positive and negative poles of the battery are turned forward, do not put it in place, otherwise the printed circuit will be burned. vs. Pay attention to changes in temperature to ensure professional thermal dissipation. Non-professionals do not open the printed circuit Three. Instructions for lithium battery 1. The characteristics of lithium batteries: The load methods of lithium batteries and mobile phones batteries are completely different. Lithium batteries have no memory and can be loaded at any time without overload or discharge. 2. The first charge takes at least 6 hours, then the green light light turns on, no need to load. 3. A special mention is made of using a "three-level" charger with overload protection, reverse connection and short circuit protection; 4. If the battery is not used for a long time, it must be fully charged and stored. Usually, charge and discharge after about three months; four. Manual of the flashlight 1. When using a flashlight, please choose according to the voltage and requirements of the battery of the flashlight. Please do not use it at random, so as not to burn the printed circuit. Do not use batteries of different types and voltages at the same time. 2. During use, when the brightness of the flashlight changes significantly, it must be disabled to prevent excessive discharge from the battery. 3. Thermal dissipation skills: The flashlight must dissipate heat when used. When the battery needs to be fully charged, it is best to use the second speed first, so that the lamp holder and the battery can extend the life of the product! Do not head the flashlight to the human eyes, because the flashlight is very brilliant and dazzling, so as not to disrupt the view, especially the children's view. Friday. Troubleshooting 1. Check the battery: Make sure the battery has been loaded and installed in the right direction. Do not use batteries of other brands and do not mix old and new batteries. 2. Check the rear cover: Make sure the switch has been tightened and the contact is good, and that the copper pillar of the rear cover is in good contact with the metal plate of the attachment ring of the rear cover. Be careful if the headlights are loosened.
