Instructions for use and precautions
1. Instructions for use
1.The battery has the positive pole facing inward (on the side of the lamp head).Negative pole facing out (tail).
2.The switch is at the end.
2. Use method
Press the rear switch of the flashlight and shine the flashlight on the item you need to test.
3. Instructions for using the circuit board
1Our store's flashlights adopt advanced voltage and constant current technology, which can effectively solve the problem.LEDRequirements of flashlights for stable voltage and constant current;
2, Special tips:
Do not use it over voltage, and do not exceed the voltage4.2V；
The positive electrode of the battery faces forward, do not reverse it. Although it has an anti-connection function, try not to try;
Pay attention to controlling the temperature change of the flashlight to ensure heat dissipation;
Non-professionals should not open the circuit board;
4. Battery
1The natural discharge rate of lithium batteries will release about its charge every day when not in use 1% Or less, although it is slow, it is prevented from being placed for too long;
2Pay attention to the waterproof, moisture-proof, drop resistance, etc. of the battery;
3, Special reminders to use a "three-proof" charger that prevents overcharging, reverse connection, and short circuit;
4If the battery is not used for a long time, the battery should be fully stored and charged and discharged again in about three months;
5, must-see is very important: the flashlight battery is used until the voltage is not lower than3VIt's about to be charged, so don't use the battery to think about charging. At this time, the battery can easily be damaged, and the battery will not be charged and then damaged. If this happens, please don't worry. You can go to the local place to repair your mobile phone. If you activate it with a higher voltage, you can usually repair it. Please do not use batteries below3VCharging, if the battery voltage is too low, causing the battery to fail to charge and damage the battery is not covered by the warranty.
5. Instructions for using the flashlight
1When using the flashlight, choose according to the flashlight's requirements for voltage and battery. Do not use it indiscriminately to prevent burning the circuit board. Do not use batteries of different models and voltages at the same time;
2During use, when the brightness of the flashlight becomes significantly dimmer, charge it immediately.
3Heat dissipation skills: During use of the flashlight, it is necessary to ensure heat dissipation. It is recommended that when lighting it, it should dissipate heat or turn off it in time according to the heating condition of the flashlight, and wait until the temperature drops before lighting it up for heat dissipation;
4Strengthen precautions against the flashlight's instructions on waterproofing and shockproof;
5Keep the inner wall of the lamp cup clean and never use your hands or compare it. Wipe with a hard object; remove fingerprints on the lens, and use a cotton swab and lens cleaner to gently rub it;
6Do not direct the flashlight light directly into people's eyes. It is super bright and dazzling to avoid affecting vision, especially children;
7If you don't use the flashlight for a long time, remove the battery (one month or more)，Avoid chemical corrosion.
6. Protection instructions
1Do not contact the flashlight with sunlight, water, chemicals and corrosive gases for a long time to avoid damaging the protective layer of the flashlight:
2, in order to maintain "O”Shape rings and threads rotate smoothly, according to the annual2-3Rub Vaseline oil on its surface twice;
VII. Troubleshooting
1Check the battery: Make sure the battery is charged and install the battery in the correct direction. Do not use batteries of different brands, and do not mix old and new batteries;
2Inspect the tail cover: Make sure the switch is tightened and in good contact, and ensure good contact between the copper pillar of the tail cover and the metal sheet of the tail cover pressing ring;
3Pay attention to whether the lamp holder is loose.
