Instructions for use
1. Check the battery: make sure that the battery is charged and the flashlight is installed in the correct direction;
2. When the headlight is in use, choose according to the voltage and battery requirements of the flashlight. Don''''t use it indiscriminately to prevent burnout of the circuit board. Don''''t use batteries of different models and voltages at the same time;
3. In use, when the brightness of the headlight changes significantly, turn off the headlight to prevent over-discharge of the battery, and charge it in time; pay attention to the waterproof, moisture-proof, and drop-proof of the battery, and charge according to the charging speed of the charger , After the indicator light changes, take it out in time, don''''t overcharge;
4. If the battery is not used for a long time, the battery should be fully charged and taken out for storage. Normally, it should be charged and discharged again in about three months to avoid chemical corrosion;
5. Keep the inner wall of the lamp cup clean. Do not wipe it with your hands or hard objects. To clear the fingerprints on the lens, you can wipe it gently with a cotton swab dipped in lens cleaner;
6. Do not keep the headlamp in contact with sunlight, water, chemicals and corrosive gases for a long time to avoid damage to the headlamp;
7. Non-professionals do not disassemble, to prevent damage to the circuit board structure.
