Instructions for Use

1. Check the battery: Make sure the battery is charged and installed in the correct direction like a flashlight.

2. When using a flashlight, choose it based on the voltage and battery requirements of the flashlight. Do not use it randomly to avoid burning out the circuit board. Do not use batteries of different models and voltages at the same time.

3. During use, when the brightness of the flashlight changes significantly, turn it off to prevent over-discharging the battery and charge it in time. Pay attention to the battery's waterproofing, moisture-proofing, and shockproofing, etc. When charging, according to the charging speed of the charger, remove it in time when the indicator light changes. Do not overcharge.

4. For batteries that have not been used for a long time, they should be fully charged and maintained. It is normal to charge and discharge them once every three months or so to avoid chemical corrosion.

5. Keep the inner wall of the lamp cup clean. Do not wipe it with your hands or hard objects. Remove fingerprints on the lens. You can use a cotton swab dipped in lens cleaner to gently wipe it.

6. Do not expose the flashlight to sunlight, water, chemicals or corrosive gases for a long time to avoid damaging it.

7. Non-professionals are not allowed to disassemble the flashlight to avoid damaging the circuit board.

Iii. Precautions

Do not shine light directly into your eyes to avoid causing harm to them.

2. Do not use under overvoltage. The voltage should not exceed 4.2V. Do not reverse the battery, otherwise the circuit board will be burned out.

3. When charging, please make sure to identify the positive and negative terminals of the charger. Do not overcharge or overdischarge the battery to avoid damaging its service life. (The charging time is generally 5 to 8 hours.)

4. When using the flashlight, check that all threads are tightened without any looseness; otherwise, it may cause no light or only a slight light.

5. Flashlights should be kept away from direct sunlight or high-temperature environments. After not in use, please remove the battery, fully charge it and store it in a cool and dry place.

6. The company flashlight is waterproof for daily use and generally won't have any problems when exposed to rain. However, it doesn't have diving functions. Please do not carry this flashlight for diving or leave it in water basins or bathtubs for a long time.

7. To ensure smooth rotation of O-rings (sealing gaskets) and threads, please apply vaseline oil or similar substances to their surfaces 2 to 3 times a year.

Four, Charging Instructions

The deficiency should be replenished in time to avoid affecting the battery life. The battery should also be charged during long-term storage.
