1. Usage Instructions
1. Check the battery: Ensure the battery is charged and installed in the correct direction for the flashlight;
2. When using the flashlight, select it based on the voltage and battery requirements of the device. Do not use it indiscriminately to avoid damaging the circuit board. Do not use batteries with different models or voltages simultaneously.
3. During use, turn off the flashlight if there is a significant change in its brightness to prevent over-discharge of the battery, and charge it promptly; also, pay attention to the battery’s resistance to water, moisture, and drops. When charging, remove it immediately after the indicator light changes, avoiding overcharging.
4. For batteries that have not been used for a long time, ensure they are fully charged and kept in use. It is recommended to charge and discharge them once every three months to prevent chemical corrosion.
5. Keep the inner wall of the lamp cup clean; do not use hands or hard objects to wipe it. Remove fingerprints from the lenses, and you can gently wipe them with a cotton swab dipped in lens cleaner.
6. Do not expose the flashlight to sunlight, water, chemicals, and corrosive gases for long periods of time to prevent damage to the flashlight;
7. Non-professionals should not disassemble the flashlight to avoid damaging the circuit board.
II. Precautions:
1. Do not direct light onto the eyes to avoid causing damage to them;
2. Do not use above the specified pressure limit; the voltage should not exceed 4.2V. Do not reverse the battery, otherwise the circuit board may be damaged;
During charging, make sure you identify the positive and negative terminals of the charger. Do not overcharge or over-discharge the battery to prevent damage to its lifespan (the charging time is typically 5–8 hours).
4. When using the flashlight, check that all threads are tightened and secure; otherwise, it may result in no light or very faint light.
5. Flashlights should be avoided being placed in direct sunlight or high-temperature environments. After use, please remove the battery, charge it fully, and store it in a cool and dry place.
6. The company flashlight has water resistance for everyday use; it will not malfunction under normal rain, but it does not have a diving function. Please do not use this flashlight for diving or keep it in a bathtub or water basin for extended periods.
7. To ensure smooth rotation of the O-ring and threads, apply vaseline or similar on its surface 2–3 times per year.
III. Charging Instructions:
If there is a shortage, it should be replenished promptly to avoid affecting battery life; the battery also needs to be charged during long storage periods.
