Using the Fenix TK75 flashlight is easy. First, insert four 18650 rechargeable Li - ion batteries (not included) into the battery compartment, making sure to follow the correct polarity to avoid reverse polarity protection kicking in. Then, use the dual - button switch in the front to turn it on and switch between different brightness levels. On high settings, it can run for a few hours, so plan your usage accordingly. When you see the low - voltage warning, it's time to replace the batteries. To maintain your flashlight, keep it clean and dry. Avoid dropping it or exposing it to extreme temperatures. Since it's made of durable aircraft - grade aluminum with a hard - anodized finish, it can handle some rough use, but still treat it with care. Also, don't forget to check the lens regularly and clean it gently if there's any dirt or smudges on the anti - reflective coating.
