Using the UCO Sitka+ Lantern is easy. First, make sure the 8800mAh Lithium - Ion battery is fully charged. You can use the USB power output to charge other small devices if needed. To adjust the height of the light, simply use the integrated extension arm to raise it from 32cm to 66cm for more light coverage. The infinity dial on the lantern is for adjusting the brightness. Turn it clockwise to increase the light up to 500 lumens, and counterclockwise to enter the Northern Lights Color mode. When not in use, store the lantern in a dry place. Avoid exposing it to extreme temperatures. To keep it in good condition, clean the LED bulb and the body of the lantern with a soft, dry cloth. If the battery life seems to be getting shorter, consider replacing the battery with a new 8800mAh Li - ion battery.
